Compare Cameron's innovative centrifugal compressor technology

with other compressors, and the advantages are clear.

Cameron’s integrally geared centrifugal compressors represent the latest technologyoffering significant advantages over outdated, less efficient and more costly

compressor designs. These advantages are inherent in the centrifugal design and

enhanced even further by Cameron’s more than 55 years of centrifugal experience.

The Advantages of Centrifugal Compressor Technology

C A M E R O N ’ S C E N T R I F U G A L C O M P R E S S O R S O T H E R C O M P R E S S O R S

• No wearing parts requiring regular replacement

• Oil filter elements and seal gas filter elementsare easily replaced online

• Require regular maintenance and periodic replacement ofpiston rings, gland packing, and valve plates

• Result in high operating expenses and significant machine downtime

• 100% oil free

• Prevent contamination of system

• Meet strict downstream requirements

• Oil filters must be installed at discharge

• Potential for oil carryover that fouls the process

• Oil will pollute process

• Pulsation-free and require no dampers

• Require the use of large pulsation dampers that reduces

pressure fluctuations

• Optional inlet guide vane control plus bypass forconsistent gas delivery under most conditions

• The use of cylinder unloading for stepped flow control canresult in complicated process control due to sudden changesin capacity

• Capable of handling substantially higher volumesof gas in one or two small casings for a smalleroverall package

• Can have four or six cylinders requiring more space for installation

• Additional redundant compressors are typically required

• Essentially vibration-free

• Requires only a pad suitable for supportingthe static weight of the package

• Require large and deep foundations to handle heavy weight

and unbalanced forces• Precaution must be taken to prevent transmission of vibration

to other equipment

Cameron offers a complete range of seal arrangements

to meet the specific needs of your application.

Babbitted-Style Gas Seals

• Used with high-pressure and nitrogen applications

• When used with educting, these seals have a high

recovery rate

• Knife edges on pinion cut into the babbitt material

on seal for closer fit and low leakage

• Babbitt material has a high tin content for lubricity

• Seal maintenance is not required for five to six years

under normal use

• Ports can be machined in the seal to recover process

gas or buffer the seal during periods of non-use

Carbon Ring Seals

• Cameron’s design has two solid, floating

carbon rings with close shaft clearance

• A non-contacting seal; Periodic maintenance

is not required

• Complete assembly bolts inside the scroll; Is

accessed by removing the impeller

• Leakage control is significantly better than the

babbitt seal for the same pressure

Single or Tandem Dry-Face Seals with

Buffered Backup

• Used on hydrocarbon and process gases

where leakage is not allowed or high-pressure

applications where labyrinth seals cannot provide

enough leakage protection

• Seal system is completely oil-free

• Buffer gas pressure can be set so that no buffer

gas enters the process but a small amount of

process gas vents out of the system

Other Types of Seals

• Oil bushing seal with separate seal oil system

• Custom options available

Cameron’s standard dry-face seal uses a floating

self-centering rider. The clearance fit allows the seal

to be easily removed and installed without puller

tools. The seal comes as a complete assembly with

an installation plate. These drawings show some of

the mechanical details.

Gas seal support systems are designed,

built and tested per API-614 standards.

System designs can be based on

differential pressure control, flow control,

or other methods. The scope of supply

is virtually unlimited. Fully automatic,

manual, or customer-specified systems can

be engineered for any gas seal type.

Systems are designed with instrumentation

to monitor seal condition. Filters and

accessories are supplied with sufficientinstruments to plan maintenance and

minimize downtime. The goal is to save

you time and money by providing worry-

free operation of your equipment and

simple maintenance when required.

MAESTRO™ PLC-Based Controls

Customer-Defined PLC Controls

PLC-based systems are used for packages with high I/O

counts, multiple gas circuit control loops, and multiple

processes. PLCs by all major industrial suppliers are

available. We can design, program, and supply your

specified PLC system mounted and wired to your

compressor package.

• PLC system is fully tested

by our Control Engineering

department before shipping.

• Logic diagrams and

programming software

are standard.

• Control systems can be

locally mounted on the skid,

designed with local I/O and

remote processors, or any

buyer-defined arrangement.

• Control system enclosures

and wiring are available for

US and IEC applications,

Class II/Zone II, and non-

hazardous installations.

Flow Arrangement

Cameron’s centrifugal compressors feature an

arrangement of flow components. Advantages of this

arrangement include:

• Flow is directed so turbulence-induced frictionis reduced.

• Depending on the application, the flow may be

cooled between stages.

A Better Packaging Concept

Cameron’s cutting-edge packaging concept gives you

flexibility to tailor a centrifugal compressor to your

needs while simplifying installation and maintenance.

Our MSG packages include:

• A lubrication system • Intercoolers

• Shaft coupling • Interstage piping

• Driver • Control panel

We can build standard compressor packages or

specialized API-672/API-617 packages, all on a common

baseplate, sensibly packaged.

Advanced Lubrication System

Cameron’s standard self-contained, low-pressure

lubrication system:• Includes an oil reservoir, mechanical oil pump,

electric full-flow auxiliary oil pump, fixed bundle oil

cooler, single full-flow oil filter, safety devices, and

instrumentation for safe compressor operations

• Is assembled and packaged on a compressor

base frame when compressor and intercooler(s)

layout permits

• Can be sized to serve the main driver

• Can be designed to meet customer specifications:

API-672, API-617, API-614, and Process Industry

Procedures (PIP)

• Includes interconnecting piping between the

lubrication system and compressor when compressor,

intercooler(s), and main oil pump arrangements permit

Intercoolers Guarantee Maximum Heat Transfer

Our ASME-coded intercoolers (European Code, China

Code, Russian Code, Korea Code, and others as required)

provide efficient cooling between stages and aredesigned to be accessible for inspection and cleaning.

• Gas-in-shell or gas-in-tube design can be selected as

dictated by the application.

• Extended surface, plate-fin design provides maximum

heat transfer with minimum space requirements.

• Accessible, smooth bore tubes are easily rodded with

bundles in place.

• No disassembly of any other part of the compressor is

necessary to perform.
