GAS DEHYDRATION (TEG)

SYSTEM DESIGNProSep’s gas dehydration system is designed specifically to meet the required dew point depression for the given gas stream. The water-rich glycol stream is regenerated to high glycol concentrations.

A typical glycol dehydration and regeneration system consists of the following components:

• Gas scrubber (may be integral with the contactor)

• Glycol contactor

• Flash drum

• Glycol filters

• Reboiler with still column and reflux condenser

• Stripping column (when required)

• Surge tank

• Heat exchangers

• Glycol pumps

BENEFITSProSep designs and builds systems to site-specific requirements by engineering every gas dehydration system with the latest process simulation software. The detailed design of the equipment considers performance, operability, reliability and safety.

• Compact packaged design

• Easy operation

• High dehydration capacity

• Minimal glycol losses

• Environmentally friendly

• Reduced on-site time and costs

GAS DEHYDRATION SYSTEM

ProSep offers customized gas dehydration systems, for the removal of water vapor from gas streams, to the oil and gas industry. Dehydrating the gas prevents hydrate formation and reduces corrosion in pipeline transmission and gas injection applications. ProSep designs and fabricates gas dehydration systems using triethylene glycol (TEG) to absorb the moisture from the gas stream.

TECHNOlOGYFrom the scrubber, the wet gas enters the bottom of the contactor tower for counter-current contact with the glycol, which absorbs the water from the gas. The contactor and internals are optimized for duty. Dehydrated gas is discharged from the top of the tower, while the water-rich glycol is routed to the regeneration process.

In the regeneration process, the water-rich glycol is heated in the still column reflux condenser, followed by the glycol/glycol heat exchangers. At this elevated temperature, entrained gas and hydrocarbons are removed from the glycol in the flash drum. Removal of the hydrocarbons helps to prevent foaming in the still column. The flash drum also helps to reduce levels of CO2 and H2S which may be present in the glycol.

The still column and reflux condenser recover valuable glycol from the vapors leaving the reboiler. Fractional distillation mechanisms within the packed section of the still column, where the cold rich glycol is fed to the reboiler, achieves this separation. The glycol, once through the still column, enters the reboiler where either a gas fired or electric heater controls the operating temperature.

In cases requiring lower gas dew points, the use of stripping gas achieves a higher TEG purity. The stripping gas is passed over the lean glycol from the reboiler in a counter-current contactor. The stripping gas provides a final stage of TEG dehydration by absorbing an amount of the water.

The lean glycol is cooled by the glycol/glycol heat exchangers before entering the surge drum, which provides a buffer volume for the system. Positive displacement pumps pressurizes the lean glycol from the surge drum up to the contactor operating pressure.

Prior to the entry into the contactor, the gas/glycol cooler cools the lean glycol to ensure the temperature is approaching the gas temperature.

CONTROl SYSTEMS AND COMMISSIONINGThe system employs automatic control. Monitoring may either be local or integrated in the centralized control system of the plant.

ProSep offers full commissioning support and start up assistance to ensure the equipment is fully operational as quickly as possible.

TECHNOlOGYAir at atmospheric pressure enters into the compressor through an intake filter and is compressed to the desired pressure. The compressed air is then dried, purified, and heated to the operating temperature. The membranes selectively remove O2, H2O, and CO2 from the feed, leaving a nitrogen-enriched stream as the primary product, as shown in the illustration.

Air separation is accomplished through a solution-diffusion mechanism in modules of hollow fiber polymeric membranes. Each module contains several hundred thousand of these fibers in bundles. Air fed under pressure to one side of the membrane dissolves and diffuses across the polymeric material. It desorbs permeate at the lower pressure side of the membrane. Each constituent dissolves in the polymer matrix to a different extent and permeates at a different rate.

As a result, the more rapidly permeating components such as O2, CO2, and water vapor will concentrate in the low pressure stream, which is safely vented to atmosphere. The more slowly permeating components (e.g., nitrogen and argon) are retained in the high pressure stream and are removed as the inert gas product.

NITROGEN MEMBRaNE SYSTEM

CONTROl aND BaCKUP SYSTEMSThe controls are normally selected in close cooperation with the client, based on requirements for purity, product pressure, flow rate and turndown. Both manual and automatic control systems may be employed. Monitoring may be local or integrated in the central plant control system.

ProSep can also offer nitrogen compressors/intensifiers and buffer tanks downstream nitrogen membranes, in order to meet demands during peak production periods.

About ProSep




EXPERIENCEThe ProSep team has designed, engineered, fabricated, installed, and commissioned over 220 membrane separation units for natural gas applications in over 15 different countries. Proven by performance data collected from numerous membrane separation unit installations and close relationships to both CA and PI membrane manufacturing / research efforts, ProSep personnel have extensive experience with gas separation membrane contamination effects and performance characterization over time. ProSep provides operations assistance and technical field service from project execution through commissioning / start-up to post-commissioning service.

TECHNOLOGyProSep membrane separation units are designed to selectively reduce the CO2, H2S, and H2O content of natural

gas. Unlike the holes and pores associated with filter technology, the separation relies on the principle that gases dissolve in and diffuse through thin polymer membrane. Certain gases, primarily CO2, H2S, and H2O, will pass through or permeate across the polymer membrane faster than will hydrocarbon gases, due to a difference in the solubility of these gases in the polymer and the rate at which these gases diffuse through the polymer membrane structure. The actual permeability of a given component is a function of the feed gas pressure, feed gas temperature, and component feed gas concentration. Gas membrane separation is a concentration-driven process which is directly related to the pressure of the gas inlet and permeate streams; the component partial pressure difference across the membrane drives the separation. The diagram below illustrates a simple gas membrane process. Given a feed stream of CO2 and CH4 at a given pressure, CO2, being the more permeable component, will more readily pass through the membrane to the lower-pressure side of the membrane and exit as the permeate stream. CH4 remains on the high-pressure side of the membrane and exits as the residue stream with essentially no pressure loss. Both CO2 and CH4 permeate through the membrane, resulting in a residue stream being more concentrated with CH4; the permeate stream, with CO2. Essentially, quickly permeating components will become enriched in the low-pressure permeate stream while slower permeating components (hydrocarbons) are concentrated in the residue stream.

wATER BATH / INdIRECT HEATER

When treating water-saturated feed gas, a water bath (indirect heater) or heat exchanger is used to “super heat” the gas to 20-25 degrees F above the dew point to ensure free water does not condense inside the membrane tubes.

SINGLE-STAGE ANd TwO-STAGE MEMBRANE SySTEMS

ProSep has the experience to optimize your gas sweetening membrane system and meet client objectives of pipeline CO2 specifications, hydrocarbon recovery, and overall system efficiency, typically with a single-stage membrane system. In some instances, however, a two-stage system is required to achieve maximum CO2 content in the permeate stream and maximum hydrocarbon recovery to the sales pipeline. Performance of two-stage systems can achieve greater than 99% hydrocarbon recovery in the sales gas stream.

CO2 SwEETENING MEMBRANE SKId

ProSep CO2 sweetening membrane skids are modular in design and construction, lending themselves to easy scalability as production volumes and CO2 concentrations vary. As indicated in the previous section, the separation process is governed by partial pressures of the various gases and their associated permeability rate. As the produced gas passes across the membrane surface, there is little pressure drop from the inlet to the sales gas stream.

GAS PRE-TREATMENT SKId

ProSep can assist the producer in protecting the system from liquid carry-over and other contaminants from upstream equipment by using pretreatment equipment, consisting of one or more of the following: 1) high-efficiency coalescing filter, 2) guard bed containing activated carbon adsorbent, 3) polishing filter, 4) thermal swing adsorption unit, and 5) mechanical refrigeration unit. This equipment removes small liquid aerosols, particulate matter, and certain heavy and aromatic vapor-phase hydrocarbon contaminants as required.

A CUSTOMER’S EXPERIENCE

In 1994 our client’s amine tower developed a small rupture that would have cost an estimated $1.2 million and one year to repair. ProSep personnel refurbished and shipped two small membrane separation unit skids to the site within six weeks and installed them within seven days. In less than two weeks from the time of arrival, 50% CO2 gas was being processed to below 10% CO2. The customer converted the original one-year lease to a purchase, and the two membrane separation unit skids operated for over five years without any replacement of parts or membrane modules. The equipment remains in operation today.

ProDry GAS DEHyDrATIoN WITH THE ProSEP CoNTACTor

PRODRY GAS DEHYDRATION

Building on ProSep’s long experience with co-current contacting, a Joint Industry Project (JIP) comprising ConocoPhillips, Total and StatoilHydro is addressing the potential of gas dehydration with the ProSep contactor.

The JIP has had encouraging results, verifying:

• Reduced size and weight at actual process conditions

• Operational robustness and advantages related to turndown, flooding, foaming and hydrocarbon liquid entrained with feed gas

• ProDry more competitive the higher the pressure and feed rate

ProDry replaces contacting towers with an inline injector/mixer. This technology has been widely used for H2S removal from gas using scavengers. ProDry saves footprint, weight and operating expenditures related to chemical consump-tion, storage and handling.

BENEFITSApplications with 1- or 2-stage ProDry:

• Debottlenecking of existing dehydration units (1-stage ProDry)

• Fuel gas dehydration (1- and 2-stage ProDry)

• Dehydration for gas reinjection (1-stage ProDry)

• Long distance transportation with moderate and low dew point reduction (1- and 2-stage ProDry)

• Subsea gas dehydration

ProMix M100 inline Mixer

APPLICATIONS

PRODUCTION CHEMICALS

Optimal performance of production chemicals such as flocculants, emulsion breakers, scavengers and inhibitors depend on high fluid exposure which is achieved with the M100 mixer. The M100 performance can prevent overdosing, which is a serious problem not only for operational costs, but also for its effects on the downstream fluid processing.

MULTIPHASE MIxINg

The ProMix M100 ensures a homogeneous multiphase distribution in the pipe with low pressure drop. Homogeneous multiphase mixing is essential for accurate sampling in quality control and production monitoring activities. For upstream mass flow meters and heat exchangers, multi-phase mixing is also crucial.

The ProMix M100 inline mixer achieves homogenization of multiphase flows with low associated pressure drop and results in separable droplet sizes. Shearing forces in the multiphase flow are controlled and more evenly distributed with the ProMix patented design than in any other mixing device, resulting in uniform droplet distribution.

LIqUID-LIqUID MIxINg

Gentle but effective mixing of two liquid streams with a low pressure drop is a main application for the M100. The M100 guarantees a homogeneous mix in any part of the process requiring it.

PRODUCED WATER TREATMENT

The M100 inline mixer is one of the key process components of the CTour produced water treatment system, in which it is used to re-mix condensate and produced water, to extract and coalesce the hydrocarbons in the produced water stream.

OIL DESALTINg AND DEHyDRATION

As part of the ProSalt system, the M100 mixes wash water as narrow-banded droplets of separable sizes into a crude oil stream to achieve even-sized water droplets that are easily separated downstream.

TECHNOLOgy

The mixer has similarities to a cylindrical plug valve with an internal cylinder. By rotating the cylinder, the pressure drop and the degree of mixing can be adjusted. In addition, the cylinder can be designed with a full bore position that allows the pipe to be pigged, which is impossible with static mixers.

The internal cylinder at the inlet side is fitted with channels pointing towards a common focus line in the center of the mixing chamber. In this way the whole chamber is utilized and efficient multiphase mixing is achieved with a low pressure drop. At the outlet side, the channels are oriented in parallel to the pipe axis to straighten the flow.

IN-DEPTH ANALySIS AND TAILORED CHANNEL DESIgN

Since the pressure drop can be pre-determined by the geometry of the channel pattern at the inlet and outlet sides of the mixer, the ProMix M100 inline mixer is always tailored to its particular application and can be designed to accommodate a wide turndown.

BENEFITS• Adjustable degree of mixing

• Low pressure drop

• Allows for pigging

• High turndown ratio

• Compact design

ONSHORE/OFFSHORE UPSTREAM OIL PROCESSING


SEPARATOR: OIL STAbILIzATION

ProSep can provide two-phase (gas / liquid) or three-phase (gas / oil / water) separators depending on the client’s particular needs (based on API 12J Standards). A typical oil train may consist of several stages of separators to stabilize the liquid, depending on the reservoir’s depth (which would determine the level to which there is a need for depressurizing the production from the well) and the amount of gas associated with the inlet production to the treating facility.

Generally, separator sizing is based on gas quality performance, neither addressing oil nor water quality. Therefore, the amount of oil / water separation in a three-phase design can vary greatly with oil API gravity and GOR.

fREE wATER KNOCKOUT (fwKO): bULK wATER REMOvAL

ProSep’s FWKO designs are based on empirical data developed over 30 years of practical experience. Two-phase (oil / water) or three-phase (gas / oil / water) designs are available. An FWKO can be looked at as a separator designed to meet an oil quality requirement.

TwO PHASE HIGH PRESSURE SEPARATOR

TYPICAL CRUDE OIL PRODUCTION TRAIN


DEHYDRATOR: MEETS SPEC OIL REqUIREMENTS

ProSep’s unique vertical grid design allows us to employ a horizontal flow pattern that can be operated either as a two-phase (oil / water) or three-phase (gas / oil / water) unit. In addition, we can combine our mechanical coalescer elements with our vertical grid system to ensure product specification adherence. Normally, dehydrator designs are employed in production fields where external heat sources are available or the number of process units is dictated by the heat load requirements. In the latter case, a line heater may be utilized to meet the heat load requirements. To meet high throughput requirements, we offer double-ended designs with multiple electrostatic zones with variable field densities.

DESALTER: REDUCE SALT CONTENT IN THE OIL

ProSep can provide desalting systems to meet your requirements. Depending on the salt content at the beginning of production and the outlet oil specification, crude desalting can be accomplished by various processes. We go from simple dehydration up to multiple stages of dehydration combined with dilution water injections to reduce the overall salt concentration. Dehydration units (thermal treaters, dehydrators) used to desalt are called desalters.

As the name implies, only free water is removed from the production inlet stream, leaving the emulsified water in the outlet oil stream. The percentage of emulsified water in that stream depends on the oil API gravity. Meeting this requirement requires operating at a particular treating viscosity combined with a calculated retention time. We address the treating viscosity requirements by heating the production stream as shown in the diagram (left) with scavenged heat or by adding internal firetubes to the FWKO itself.

THERMAL TREATER: MEETS SPEC OIL REqUIREMENTS

ProSep’s thermal treaters combine both heating and coalescing capabilities in one efficient process unit. ProSep designs the heating section to meet the treating viscosity requirements of the coalescing section. Two-phase (oil / water) or three-phase (gas / oil / water) designs are available with either mechanical or electrostatic coalescing elements.

Typically, thermal treater designs are employed in production fields where the number of process units required is based on the coalescing design and not the heating demands. The treating temperature for a thermal treater is considerably higher than that for an FWKO in order to meet the stricter water content specification by removing the remaining emulsified water from the process stream.

THERMAL ELECTROSTATIC TREATER

ELECTROSTATIC DESALTER


DESALTING TECHNOLOGYA system can desalt by two methods: (1) dehydration and (2) dilution, or changing the produced water solution concentration. Most of the salt (99.99%) is in solution in the water, so removing the water associated with the oil also removes the salt at the same time. If the salt concentration is very high, however, then even removing 98% or more of the associ¬ated water may not meet the oil salt content specification. The next step is to reduce the salt concentration in the associated water by mixing it with dilution water with no salt (freshwater) or a smaller concentration of salt (brackish water).

Again, several stages of dehydration and dilution may be required to meet specification. This is dependent on the inlet production cut and salt concentration.

The ability to introduce the dilution water into the process stream without creating an emulsion and at the same time developing a homogeneous mixture between the dilution water and the brackish produced water is essential to this design. ProSep offers ProSalt an injector / mixer system that improves efficiency in water consumption and downstream dehydration.

one problem. This can be illustrated by designs that allow the following:

• Operation with a gas phase, thus eliminating the need for a degassing vessel before an electrostatic dehydrator.

• Installation of mechanical coalescers in the inlet section to reduce the water cut to acceptable levels before entering the electrostatic field, thus increasing the inlet water cut that a dehydrator can process.

• Placement of firetubes in various locations in process systems to improve efficiency and streamline necessary equipment.

• Oil Phase Coalescence (Mechanical Elements, Vertical Electrostatic Grids)

• Outlet Phase Management (Vortex Breakers, Weirs)

• Solids Removal (Sand Wash and Extraction Systems)

• Firetube Protection (Detection and Wash Systems)

APPLICATIONS

• Liquid stabilization through the removal of gas

• Removal of free water from the oil phase

• Removal of emulsified water from the oil phase to a specified level, or in the case of desalting, to allow the salt to meet a specified maximum

• Reduction of salt concentration, which may be required to meet specified maximum (via dilution water)

TECHNOLOGY

ProSep’s separation technology is based on a horizontal flow regime. From FWKOs to desalters, the horizontal flow pattern allows us to provide two-phase and three-phase designs that maximize vessel utilization for each component.

As the process progresses through the vessel and the water droplets suspended in the oil phase coalesce into larger droplets, they finally reach the critical particle diameter where Stokes Law begins to apply. Stokes Law defines the terminal settling velocity of a particle of a particular size as it falls through a fluid. The terminal settling velocity is perpendicular to the horizontal process flow velocity. This can be particularly critical in equipment designed to produce 0.5% BS&W or less where the droplet population is reduced and smaller coalesced droplets may be formed. As you can see from the vector analysis below, a unit utilizing an upflow design creates a velocity vector directly opposite to the vector created by Stokes Law. The conclusion is that if all parameters in Stokes Law are fixed, a horizontal flow regime can remove a smaller droplet size, which translates into a more efficient system.

A big advantage with a horizontal flow regime comes with the design of a vertical electrostatic grid system. As the oil phase progresses downstream through the vessel it can be exposed to multiple stages of electrostatic fields of varying potentials. Built-in adjustability allows these fields to match the water content remaining in the oil phase, thus ensuring complete and efficient dehydration. One additional advantage is the facility to incorporate mechanical coalescers in combination with the electrostatic grids. These coalescers can be placed in the process stream to provide either bulk or polished coalescence.

About ProSep



ProSep’s innovative offerings have been awarded three Spotlight on New Technology Awards from the annual Offshore Technology Conference in Houston in 2005 and onwards, comprising the proprietary technologies ProScav, CTour and ProSalt.

A CUSTOMER’S ExPERIENCE ProSep personnel were involved in the supply of an advanced design horizontal coalescer installed in the Gulf of Mexico platform in 1998, where the coalescer’s design enabled it to significantly exceed design capacity while simplifying opera-tions. Design features that aid in enhancing performance in-clude: horizontal flow to minimize water carry-over with the bulk oil phase, cyclonic inlet device to smooth the pipe-to-vessel transition and degas the oil at inlet conditions, baffles to distribute oil flow evenly across the vessel cross section, multiple externally adjustable electrostatic grids to vary field density and allow improved coalescence, and enhanced coa-lescence packing to optimize removal of water droplets coa-lesced by the electrostatic field.

The existing upflow coalescer was frequently unable to achieve 1.0% BS&W in oil effluent at less than 50% of its design flow rate, while the horizontal flow electrostatic treater consistently provides <0.4% BS&W at 120% of design ca-pacity.

The equipment has become the standard design approach for this client.

The ProSalt system’s efficient injection and mixing technology holds the key to effective salt content removal, efficient utilization of wash water and chemicals, and improved crude-water separability. Besides increased treatment capacity, the technology allows reduced wash water requirements, reduction in oil in water content, and low installation costs and thus high returns on investment.

ProSalt is a robust, flanged spool piece that replaces the conventional static mixer and mixing valve with a novel inline injection/mixer assembly. This assembly requires minimum maintenance, has a high turndown ratio, and provides unobstructed flow conditions while providing efficient mixing of various production chemicals and / or dilution water used in desalting.

Desalting is a crucial step for crude oil downstream refining processes since both the free water and emulsified water contain salt, which can cause corrosion, leading to failure of critical process equipment, i.e. hydrocracker.

The injector / mixer system generates a homogeneous phase flow over the pipe cross-section in combination with a pressure drop that is significantly lower than conventional mixing methods, while controlling shear forces. This achieves an improved oil-water separation, with less emulsion.

ProSalt has demonstrated operational benefits for most crude oil / wash water flow rates over a wide range of specified pressure drops.

iMProved PerForManCe at installation sitesProSalt Mixer Systems are in operation at several locations, such as Saudi Aramco (16” ProSalt, 2007 onwards) and StatoilHydro (14” ProSalt, 2006 onwards). At both sites the units have shown an improved performance with respect to a lower pressure drop, reduced fresh water consumption required and less oil-in-water at the separator outlet. Lower operational expenditures were verified, especially those related to pressure drop (40-70%), fresh water consumption (20-40%) and oil entrained with the separated water. Other process improvements such as reduction in demulsifier consumption, less retention time in the separator and increased crude desalting capacity are clear potentials currently under systematic review.

BeneFits• Reduced pressure drop (40-70%)

• Reduced wash-water consumption (20-40%)

• Improved oil-water separation

• Reduced residence time in coalescer / separator

• High turndown ratio

• Easy process modification - low installation cost and high return on investment

• Reduced chemical consumption

• Flanged unit, no operator involvement requirement

ProClean SYSTeM For SanD reMoVal

FEatUREsProClean’s efficient automated solids removal system design addresses these important objectives:

• Prevent disruption to the steady-state process• Prevent large accumulations that may be difficult to

remove• Operate reliably (automated rather than operator-

dependent)• Reduce corrosion and abrasion damage caused by

solids build-up• Minimize use of jetting fluids• Adjust for actual solids loading

PROClEan dEsiGnDeveloped through years of field experience, ProClean accomplishes its objectives with these features:

• Multiple stations for localized, targeted removal• Jetting fluids that direct solids into the individual sand

pan area of influence• Independently operating stations• Brief duration jet / dump cycles calculated for optimum

vessel maintenance• Minimal jetting requirement for flushing clean• Process stability with automation• Optimized placement of components for longevity

Since accumulation of sand can interfere with the oil treating process and become detrimental, sand removal is an important function in many primary separation vessels, FWKOs, and treaters.

Most crude oils contain varying quantities of solids and heavier, more viscous oils carry additional entrained solids from producing formations. Accumulations of such solids may cause firetube failures, plugged nozzles, and obstructions that disrupt flow patterns and vessel operations.

Managing the build-up of solids is essential to trouble-free operations. Through efficient removal techniques and optimized sequencing, operators will appreciate substantially simplified annual plant turnaround activities. Frequent shutdowns for cleanout and their resulting production losses will cease to be an issue.

COMPOnEntsThe primary components (i.e., the sand pan and dump piping and the jet wash piping) of the ProClean solids removal system are bolted in and completely and easily removable from the vessel. The individual station control valves are externally mounted (not shown) and operate simultaneously. An adjustable PLC panel controls the individual stations to match exact process requirements.

Other sand removal systems typically consist of a single jet wash / dump assembly operating over the full vessel length which consumes excessive jet wash water while disrupting vessel interface levels. With the ProClean system, the operator can better control the solids removal process by being able to calibrate the operating frequency and sequencing of the independent stations to match actual solids deposition.

PROPLATE CPIProPlate CPIs are designed to provide the same removal efficiency as a traditional gravity separator in a much smaller vessel, making them ideal for fixed-platform as well as land-based installations.

ProPlate CPIs are atmospheric tanks or pressurized vessels that are equipped with polypropylene or stainless steel packs designed to enhance coalescence and separation by decreasing the distance the oil droplet must travel to be removed from the continuous phase.

For floating applications with low pressure profiles, a CPI can be designed as a liquid-packed pressure vessel, mitigating the problems traditional atmospheric CPIs have with wave motions.

PROSkIm VERTICAL SkImmERA ProSkim vertical skimmer can also serve as a motion-insensitive substitute for the CPI. Though generally larger than a CPI based on residence times of 5-15 minutes, the ProSkim vertical skimmer provides an effective motion-insensitive option. They can be fitted with coalesciing packs to enhance efficiency and reduce residence time requirements, yet still achieve performance comparable to that of a CPI.

ProSPin HYDroCYCLonES

As part of effectively treating large volumes of produced water, the ProSpin hydrocyclone separates liquids that have different densities, especially oil and water, by taking advantage of gravity and centrifugal forces. The ProSpin hydro-cyclone is an excellent primary separation solution in most offshore applications where sufficient process pressure is available, since it has a small footprint and is highly efficient at separating free oil from water.

The denser fluid moves to the walls of the hydrocyclone and is removed at the downstream fluid outlet (underflow). The less dense fluid is drawn into the low-pressure core and, by applying a back pressure to the outlet, flows back up the hydrocyclone to be removed at the upstream outlet orifice (overflow).

The ProSpin is unaffected by ship or platform motions and delivers typical removal efficiencies of 85-95% of all oil droplets >12-15 microns with effluent quality of 25-100 mg/l OiW.

PROFLOAT INDUCED GAS FLOTATION SYSTEMS

FEATURES• Contained, gas-tight design

• Compact skid design

• Simple and reliable design and operation

• No internal moving parts, no specialty parts needed

• Availability of pressurized operation

• Low skim rates

• Operational and environmental safety

• Minimal energy requirements

INDUCED GAS FLOTATIONProFloat employs induced gas flotation (IGF), as opposed to dissolved gas flotation (DGF), because of issues of solubility of inert and fuel gas at the high temperatures characteristic of produced water processes. The ProFloat IGF is available as either a vertical single-cell or a horizontal multiple-cell.

To recover oil and to condition waters for overboard discharge, re-injection or further polishing through filtration, ProSep’s ProFloat Flotation Systems deliver highly efficient removal of oil and solids (10,000 to 100,000 BPWD with a separation efficiency of up to 98%) while completely containing the process.

ProFloat is ideal for secondary treatment of produced and wastewaters in refineries, petrochemical plants and in the oilfield. The solution can integrate into existing systems as standalone vessels or be fully skid-mounted as a turnkey package.

PRINCIPLES OF IGFThe highly efficient, motion-insensitive vertical induced gas flotation (IGF) process, with its small footprint, is ideal for space-limited installations, and especially for floating production applications. The process begins by providing a venturi-type eductor with pressurized water, which passes through and creates a vacuum at the gas suction port. The gas drawn from the vapor space in the IGF is induced into the recycle stream via an eductor. The gas is then thoroughly mixed with the water and contaminants through the aid of a static mixing device. This homogenous mixture is then released into a separation vessel. “Floated” oil and solids are skimmed from the surface of the vessel, and clarified effluent exits from the bottom of the vessel.

ProSep’s IGF has a vertical design that uses Stokes law by reducing the apparent density of oils and solids by their attachment to the finely dispersed gas bubble population in the separation vessel, and by increased droplet size and buoyancy through coalescence.

Minimization of the liquid surface area susceptible to motion can be accomplished via the use of a compact and lightweight vertical single-cell or multiple vertical single-cell IGFs, as it is much easier to hold the liquid level control of a vertical vessel during operation due to its relatively small liquid surface area.

HORIZONTAL MULTIPLE-CELL IGFSThe IGF is also available in horizontal multiple-cell when higher separation efficiencies and flow rates are required. Multiple-cell units are also better at handling upsets. ProSep’s multiple-cell IGFs are ideal for many onshore and fixed offshore applications because of their ability to consistently achieve OiW concentrations near the lower limit of 15 mg/l.

BENEFITS OF PROFLOAT IGF• Energy-efficient code and non-code designs

• No hazardous off-gas emissions

• Minimal moving parts

• Single pumps (vs. multiple internal mixing mechanisms)

• Compact, customizable skid-mounted equipment

• Insensitive to FPSO and floating platform motions

• Low skimmed oil rates (typically 1-3%), minimizing downstream tankage

• Simple “set it and go” operation

• Low chemical consumption

• Low maintenance / operator intervention

BENEFITS• Deep bed design for contaminant retention reduces backwash frequency

• Influent stream utilization eliminates backwash water storage tanks and pumps

• System uses lowest backwash volume of available technologies

• Backwash cycle fully fluidizes and regenerates the media bed without additional air scouring

• “Green” technology aids in achieving “zero discharge”

• Nutshell media prevents the fouling / plugging typical of sand and multi-media filters

• Equipment has very low maintenance requirements

When treatment of produced waters needs to go beyond the results of secondary treatment (typically 15-25 mg/l of oil and/or solids), ProSep provides high-performance tertiary treatment equipment. The ProShell Deep Bed Nutshell Filter can remove 98% of non-water soluble hydrocarbons and particulates greater than 5 microns in most cases, while significantly reducing or eliminating the need for large quantities of backwash water, scouring, and surfactants.

• Stainless steel internals and high-reliability backwash pump ensure >99% operational uptime

• Media attrition measures <5% annually

FEATURESThe unique qualities of crushed pecan / walnut shells make for a media that is oleophobic and elastic, yet extremely hard and durable. These characteristics of the ProShell Deep Bed Nutshell Filter lead to greatly diminished media attrition rates combined with maximum performance.

Under normal operating conditions, with a nominal inlet oil concentration of 50 mg/l or less and a comparable solids inlet concentration, nutshell filters will produce an effluent with less than 5 mg/l of dispersed oil and suspended solids without the addition of chemicals.

OPERATING PRINCIPlESThe ProShell Deep Bed Nutshell Filter System features a highly durable media screen supported at vessel bottom and an engineered fluidization path that successfully cleanses the media of oil and particles. The fluidization nozzle is strategically located to insure complete and rapid fluidization of the media bed, reducing backwash water volumes; the scrubber screen has been designed to retain the media within the filter vessel while efficiently drawing contaminants from the vessel. Raw feed water is used during all stages of the backwash cycle.

The nutshell filtration cycle begins when dirty fluid enters the vessel through a valve. As the contaminated fluid is forced through the media bed under pressure, oil and solids are trapped and accumulate within the bed. Clean, filtered water is discharged from the bottom of the vessel. The backwash process consists of 1) fluidizing the bed to dislodge contaminants, 2) discharging the contaminant-laden water, 3) delaying for one cycle which allows for the settling of the media bed, and 4) rinsing to remove any residual contaminants from the media bed prior to bring the filter back online.

MEdIA

The ProShell Deep Bed Nutshell Filter is filled with a blend of pecan and walnut shells which are specially

conditioned and ground to a uniform size. The ratio of walnut to pecan shells maximizes contaminant retention while minimizing media attrition.

CARTRIdGE ANd ABSOlUTE FIlTERS

ProSep also offers cartridge filters with excellent removal efficiencies. As stand-alone tertiary treatment, they can become operator- and OPEX-intensive with frequent cartridge change-outs required to handle typically high contaminant loads. ProSep cartridge filters installed downstream of properly operated nutshell filters, however, offer an excellent produced water treatment solution that approaches “zero-discharge” requirements. In this scheme the ProSep nutshell filter removes the bulk of the suspended solids and dispersed oil, minimizing the load on the ProSep cartridge filters and maximizing the time between element replacements.

THE CTOUR PROCESS FOR PRODUCED WATER TREATMENT

PRODUCED WATER TREATMENT FOR THE FUTURERecently the CTour process was commissioned for full-scale installation on five different platforms in the North Sea. The platforms treat approximately 1.8 million BWPD, which represents two-thirds of the produced water discharged in the Norwegian sector.

When operated under optimum conditions, the CTour process routinely yields residual oil discharges of <3 ppm total petroleum hydrocarbons (TPH) and at the same time removes 90-95% of dangerous dissolved polycyclic aromatic hydrocarbons (PAH) components. The CTour process has been successfully developed, tested, and installed on offshore platforms and can be implemented in most production facilities where condensate is available.

The CTour process breaks ground as a step change in the treatment approach for produced waters and has served as

In response to increasing produced water volume combined with stricter legislation and constant operational con-cerns, ProSep offers the CTour process. The process is one of the only technologies in the world that can cost-effec-tively remove both dispersed and dissolved hydrocarbons from large volumes of produced water. It does this through injecting a condensate of light hydrocarbons into the produced water stream to extract the harmful components.

TECHnOlOGyThe TORRTM process consists of two inline pressure vessels, and an optional third vessel can be used as a standby.

Produced water enters the TORRTM unit for treatment and then passes through the core of multiple continuous coalescing elements. The continuous coalescing element adsorbs the small oil droplets, coalesces them to large oil globules and then desorbs them.

Gravity separation principles remove these large coalesced globules, which then rise to the top of the vessel. Any solution gas accumulating with the oil at the top of the vessel will be safely recovered. The oil and/or gas collected at the top of the vessel are recuperated and returned to a suitable collection unit.

The TORRTM technology treated produced water exceeds discharge regulations.

SEAWATER TREATMENT AND INJECTION SYSTEMS

TECHNOLOGYProSep offers customized skid packaged solutions for offshore or onshore applications. In seawater applications, raw seawater is drawn from a certain depth, typically about 100 ft, through seawater lift pumps. The raw seawater is then chlorinated using an electrochlorinator to prevent biological growth in the downstream equipment. The electrochlorinator generates sodium hypochlorite by electrolysis of seawater.

Coarse Strainers are located downstream of the seawater lift pumps. Used in seawater injection system applications, they remove large oceanic contaminants such as silt, algae and crustaceans and are typically rated for 80-100 microns. However, other micron ratings can be used depending on customer requirements. Coarse Strainers are self-cleaning, allowing uninterrupted continuous flow at full capacity during backwash.

Filtered seawater from the Coarse Strainers is then routed to either the Multi-media filters or Ultrafiltration (UF) membranes depending on the treatment process selected. ProSep offers vertical multi-media filter vessels which provide high efficiency (98%) removal of particulates greater than 2-5 microns. The ultrafiltration process provides higher quality water than multi-media filters. It is lighter and occupies less plot area than multi-media filters making it ideal for offshore floating platforms where plot area is a premium and significant weight savings can be realized. ProSep will work with different UF membrane manufacturers to meet customer requirements.

Treated water will have to be deaerated before it can be injected. Deoxygenation or deaeration removes dissolved oxygen to control corrosion and/or aerobic bacteria activity. ProSep manufactures conventional deaeration equipment such as vacuum stripping or fuel gas stripping packed towers. Water from the deaerator tower can undergo further filtration or polishing steps by using cartridge filters to provide absolute filtration performance prior to being injected.

In addition, ProSep has in-house expertise to design and deliver Reverse Osmosis Membrane Packaged Systems for both brackish (aquifer) water and seawater desalination.

The type of media and number of layers depend mainly on the client’s filtration requirements and operational conditions. Headers and laterals distribute the water entering the filter across the entire filter area.

The upper media layer matches the characteristics of the lower layers in the filter to ensure maximum utilization of the total filter bed. Typically, the system uses anthracite, garnet and sand. The particles are collected in the whole filter bed, where the depth filtration principle ensures a high deposits holding capacity.

The filters are vertical or horizontal pressure vessels with leg, skirt, or saddle supporting. They are constructed of carbon steel, painted externally and internally with epoxy, and lined either with rubber or glass flake reinforced epoxy or vinylester. Vessels made form seawater resistant materials are also available.

Either a nozzle plate or a grid made of V-shaped wire covering the cross sectional area of the filter supports the granular media.

The support collects the filtered water in filtration mode and evenly distributes the backwash and scour in cleaning mode.

Granular media filters are cleaned by reversing the flow direction through the filter bed or baskwashing the bed, thereby dislodging and flushing out the solids collected within the bed. To achieve the required cleaning intensity of the bed, the cleaning cycle includes an air scour. Backwashing of a filter can be initiated by timer, high pressure drop or reduced filtrate quality. Manual initiation of the backwash is also possible.

CONTROL ANd OPTIONS

The control of the filtration system is fully automatic and makes use of a programmable logic controller (PLC) to monitor and control the system. Depending on client preferences, control facilities, such as the logic controller, can be local and/or remote.

Depending on client requirements, ProSep also designs and supplies cartridge polishing filters and automatic backwashable coarse filters for continuous operation.
