1. Equipment description

1.1 Introduction

The Veolia Environmental Services P43 is a device or directing a submerged jet o crude oil across

a pre-selected area o the bottom o a crude oil storage tank. This jet o crude oil dissolves and re-

suspends the accumulated sludge throughout the overhead oil.

The P43 is uid dynamically-powered, the nozzles being gearbox-driven by a xed-blade impeller

assembly which is rotated by the continuous ow o uid through the P43. This is shown in

Figure 1.1 on page 3 o this section.

The P43 was developed jointly by BUTTERWORTH SYSTEMS and EXXON RESEARCH AND

ENGINEERING COMPANYas a replacement to side-entering mixers. Full scale tests demonstrated

that complete de-sludging o a tank could be accomplished in less than 30 hours using the

P43. Periodic use o the P43 eliminates the need or side entering propeller mixers resulting in

substantial electrical savings.

1.2 Types o P43

There are two types o P43 available:

CENTRAL TYPE

The centre mounted P43 is designed to be placed on the tank oor in the centre o the tank. Both

nozzles normally would discharge simultaneously through the entire 360 rotation o the P43. One

nozzle o the P43 can be blanked o to accommodate pump ow rate limitations. Single-nozzle

operation requires that the installation be designed to withstand jet reaction.

This installation can only be considered in a clean, gas ree, tank since it is necessary to conduct

hot work.

SHELL TYPE

The shell mounted P43 is designed to be placed at the tank wall, using the existing tank shell

manway or mounting.

Only the nozzle acing away rom the tank shell discharges as the P43 continuously rotates in a

clockwise direction. An internal bae (see Figure 1.1) prevents the nozzle acing the tank shell rom

discharging. The ow change over between the nozzles is smooth and commences when the

nozzles are approximately tangential to the tank shell. Flow rom one nozzle is gradually reduced

as ow to the other is increased proportionally to begin the cleaning cycle again.

The shell mounted P43 can be installed in a tank that is in service provided the manway door

can be removed or installation. Unlike the centre mounted P43, the shell mounted P43 doesnot require any hot work or installation. The shell mounted P43 aords ease o access or

maintenance and the installation can be either portable or permanent.

2. Operation

2.1 Operating specications

During the normal operating sequence o the P43, there will be external circumstances which

will lead to a change in the normal ow rate and/or supply pressure. These changes will alter the

cleaning radius o the P43 and could aect the overall eectiveness o the P43 installation.

The graphs (Figures 2.1 to 2.4) enable the operator to calculate the impact o these changes

on cleaning radius, and which remaining parameters would need to be altered to restore the

installation to its normal operational eectiveness.

EXAMPLE:

In the case o a 260' (79m) diameter tank with three P43(s) at equidistant positions around the

circumerence o the tank, the ollowing applies:

For a 100mm nozzle rom Figure 2.3 and Figure 2.4:

CASE ARange Flow Pressure drop across P43

130' (39.5m) 3375 IGPM (921m3 /hr) 83 psi (5.8kg/cm2)

CASE B

Should the ow be reduced to 3000 GPM (819m3/hr) Then rom Figure 2.4:

Range

115 (35m)

CASE C

Should the pressure be reduced by 5psi then (rom Figure 2.3) the pressure drop across the P43 will

reduce to (83-5) = 78 psi (5.48kg / cm2).

Range

126 (38.4m)

2.2 Recommended operating interval

It is strongly recommended that the P43 is run at least once per month to prevent sludge build-up

and to ensure ree movement o internal components. The requency and duration o operation

will be a unction o sludge deposition rates, but in general should be about 8 sweeps per nozzle in

a month.

MONITORING P43 EFFECTIVENESS

A tank monitoring procedure should be devised to

Determine the crude oil quality or selection o processing strategy

Measure the eectiveness o blending

Determine the rate and eectiveness o sludge re-suspension

2.3 Use o shell mounted P43 to de-sludge tank

(i) Take samples o sludge and measure:

B S & W (Bottom Sediment and Water)

(ii) Conduct sludge prole survey across the tank

Estimate sludge quantity

Empty tank and t P43 (see Section 3.3)

(iii) Fill storage tank with crude oil to a minimum height such that the roo is oating

It is advantageous to have a large volume o crude to disperse the sludge

A ratio o approximately 4:1 (crude to sludge) is usually sufcient

(iv) I a minimum level o crude has been used, raise roo legs to their operating position to

minimise jet disturbance during cleaning operation. Alternatively ll the tank to a level

where the roo legs are above the centre line o the jet

(v) Sample the crude oil ater lling the tank and measure B S & W levels

(vi) Gradually increase the pressure to each P43 until the designated rate is achieved

(vii) For the tank cleaning operation, we recommend a minimum o eight sweeps per P43. This

time can be reduced i the customer is prepared to stop the operation, allow a 1-hour settling

time and conduct sludge prole measurements. I the levels are satisactory then the operation

can be stopped

(viii) When the operation is stopped to assess sludge proles, it is recommended that samples are

taken at the top, middle and bottom to determine B S & W levels

This data will give you useul inormation on the operating characteristics o the P43 and will

assist in assessing the processing needs o this mixture

(ix) I sludge is still present in the tank and the B S & W level exceeds 15% in the bulk o the

crude oil, we recommend draining the tank and adding resh crude oil or a urther periodo P43 operation

NOTE: SEQUENTIAL OPERATION

I the renery is limited or ow rate it is possible to operate the P43 on a sequential basis.

However each P43 should be operated as outlined in section (vii). The total cleaning time would,

thereore, be extended.

Heating o the oil is also an advantage when de-sludging, with 60 C the maximum

recommended temperature.


14/45


2.4 Procedure or processing sludge dispersed in crude oil

The sludge dispersed in the crude oil mixture may need to be blended in line with the eedstock

rom a neighbouring tank. The decision on the exact percentage o the blend should be based on

the composition o the sludge / crude oil mixtures. I the P43 has been used to de-sludge the tank

with a minimum crude level, then a blend o 5 to 10% could be required.

The ollowing parameters should be monitored to assess any downstream impacts:

(i) B S & W and salt levels in the inlet and outlet o the desalter

In order to assess the ouling tendencies o the crude oil, monitor

(i) Pressure drops across crude pre-heat exchangers beore, during and ater sludge /

crude oil processing

(ii) Overall heat transer coefcients (U Values) across crude preheat exchangers,

beore, during and ater sludge / crude oil processing

2.5 Routine check on P43 operation

It is recommended that the ollowing checks are conducted periodically:

Check sludge level in the crude oil tank

Check pressure readings at tank shell and ensure these correlate with the design pressure

or the installation

Monitor line lter pressure drop to ensure that the line lter is not blocked

During P43 operation, check indicator (where tted) or correct P43 rotation

2.6 Special considerations

I the P43 is to be operated in an environment with oils which are solid at ambient temperatures,

special precautions should be taken. These include:

Keeping the temperature o the P43 and vicinity elevated

Checking that the strainer(s) is clear

Checking the indicator (where tted) to ensure the P43 is rotating

Checking the pressure and ow rate on starting against gures given or the installationsand/or previous results (see Figures 2.1 to 2.4)

Ensuring that the supply line to the P43 is drained / empty i the heat is to be

switched o

A. Installation

3.1 Equipment supplied

Veolia provide only the P43, which is lled with oil and ready to be mounted onto the appropriate

supporting pipework. The P43 is tted with an 8 inch ANSI at ace mounting ange and is

complete with xing bolts, mating ange and an earthing strap.

The P43 is supplied as a sealed unit. Breakage o this seal will invalidate warranty.

Veolia do NOT provide any o the associated pipework, supports, valves, gauges etc. However we will

give technical advice on the installation and comment on any piping proposals.

Schematics or typical pipework required or installation o the P43 are illustrated on the

ollowing pages.

Prior to installation o the P43 in any tank, ull regard must be given to saety procedures to ensure

the protection o all personnel. All standard saety procedures as laid down by governmental bodies,

saety organizations and the operating company must be complied with.

3.2 External pipework details

3.2.1 Details or centre mounted P43

A schematic o the pipework is illustrated on Figure 3.3. The ollowing should also be considered

when designing the system:

NOTE: It is possible that sufcient strainers may have been tted at the pumps, thus making

the tting o a urther strainer unnecessary.

All new pipework must be ushed through beore commissioning in order to clear any

debris that may have accumulated during installation. The use o temporary strainers

during commissioning is also recommended

Ensure centre line o jet does not directly impinge on internal piping, e.g. stream coils,

water draw-o, etc

Ensure also that all specied alterations to internal pipework have been completed

Line vents or commissioning should be included

Pressure gauges are tted to measure P43 inlet pressure and identiy i line lter

is blocking. These should be upstream and downstream o the line lter

Valve requirement. See Figure 3.4

P43 supports to withstand jet reaction quoted by Veolia

Fabrication o elbow assembly to acilitate P43 installation. See Figure 3.4

Minimum distance between vertical centre line o P43 and inside o tank well

should be *500mm or the P43 with standard nozzle attachments

Recommended clearance under the P43 125mm

Inlet ange designed to A.P.I 650 hence bolt holes straddle the centre line o the P43

Correct P43 orientation is indicated by a groove included on the main stationary component.

This groove marks the centre line o the P43 and should be directed at the centre o the tank

When steam coils are present, P43 must be positioned such that nozzle discharges below

steam heating coils

*This measurement should be increased to 800mm or P43(s) with S Bend Nozzle tube attachments

(see Section 4 Page 13).

3.3 System installation commissioning

The ollowing procedure is recommended when installing and commissioning the Veolia P43.

3.3.1 Centre mounted P43

a) Check that the correct nozzle size has been installed (i.e. in accordance with design

specication). Ensure that the impeller in the inlet to the P43 is ree to rotate (by hand)

b) Ensure by observing the centre line position o the nozzle that there will be no direct jet

impingement on internal piping e.g. stream coils, water draw-o etc. Also that all specied

alterations to internal pipework have been completed

c) To prevent impeller ouling on start-up, ensure that the lines eeding the P43(s)

(downstream rom the line lter) have been ushed to remove scale deposits, welding rods etc .

prior to installing the P43(s). The use o a temporary strainer during commissioning is to

be recommended

d) Ensure that a pressure gauge 0-20 kg/cm (0-300 psi) has been installed in the line between

tank shell and valve to measure P43 inlet pressure

e) Fit gasket between the P43 and the saddle support and tighten bolts securely. Check the plane

o the nozzle rotation to ensure that it is ree rom obstruction, and the centre line o the jet

does not directly impinge on tank internals

) The P43 is electrically continuous. To ensure electrical continuity with the pipework an

earthing strap is supplied. This should be used to bond the inlet ange on the P43 to the pipe

assembly. When assembled the whole surace o the strap and the asteners should be coated

with an oil resistant paint

g) Ensure that the external indicator (where tted) is in place and the exible drive is

securely astened

h) Ater line commissioning, gradually increase the pressure to the P43 until the designed rateis achieved

i) Monitor the position o the P43 on the external indicator ater hal an hour operation and

record the position ater a urther hal an hour period to ensure that the P43 is rotating reely.

Check the rotation rate o the P43 and ensure that it is within 10% o the specied time or the

rotation at the design pressure

3.3.2 Shell mounted P43 (or manways 30 or greater)



b) Ensure by observing the centre line position o the nozzle that there will be no direct jet

impingement on the internal piping e.g. steam coils, water draw-o etc. Also that all specied


c) To prevent impeller ouling on start-up, ensure that the lines eeding the P43(s) (downstream

rom the line lter) have been ushed to remove scale, deposits, welding rods, etc. prior to

installing the P43(s)

d) Assemble P43 into inlet pipe abrication together with gate valve and non-return valve,

see Fig. 3.4

e) NOTE: that the centre line o the P43 is marked by a machined slot. This slot must point tothe centre o the tank

) Check that the earthing strap is xed across the anges and is making a good contact and has

been painted



26/45

g) The P43 can be easily manoeuvred by crane with the valve assembly acting as a balance

h) Ensure that the external indicator (where tted) is in place and the control cables are

securely astened

i) The assembly can be positioned and the manway ange bolts tightened

j) Ater line commissioning, gradually increase the pressure to the P43 until the designed rate

is achieved

k) Monitor the position o the P43 on the external indicator ater hal an hours operation and

record the position ater a urther hal-hour period to ensure that the P43 is rotating reely.

Check the rotation rate o the P43 and ensure that it is within 10% o the specied time

or one rotation at the design pressure

3.3.3 Shell mounted P43 (or manways less than 30 )



b) Ensure by observing the centre line position on the nozzle that there will be no direct jetimpingement on internal piping e.g. steam coils, water draw-o etc. Also that all specied


c) To prevent impeller ouling on start-up, ensure that the lines eeding the P43(s) (downstream

rom the line lter) have been ushed to remove scale deposits, welding rods, etc., prior to

installing the P43(s)

d) NOTE: That the centre line o the P43 is marked by a machined slot. This slot must point to

the centre o the tank

e) To install P43(s) through manway the P43 should be positioned on the inlet pipework in such

a manner that the machined slot on the P43(s) is pointing to the tank centre and the nozzle

positions are parallel to the tank shell

nOZZLES SHOuLd nOW BE REMOVEd

) Check that the earthing strap is xed across the anges and is making a good contact and has

been painted

g) From the main liting equipment an additional chain block is required, this second lit should

then be attached with a shackle or similar to the bottom holes in the manway cover to allow

the manway to be rotated through 90

h) The P43(s) can now be tted through the manway

Having positioned the P43(s) in the tank the secondary set o chain blocks can be lowered

allowing P43(s) to resume its normal position

i) Nozzle installation will have to take place through the manway door, with the valve assembly

resting outside the tank at base level

j) Once nozzles are xed ensure that the external indicator (where tted) is in place and the

control cables are securely astened

k) The assembly can be positioned and the manway ange bolts tightened

l) Ater line commissioning, gradually increase the pressure to the P43 until the designed rate

is achieved

m) Monitor the position o the P43 on the external indicator ater hal an hours operation and

record the position ater a urther hal-hour period to ensure that the P43 is rotating reely.

Check the rotation rate o the P43 and ensure that it is within 10% o the specied time or

one rotation at the design pressure

3.3.4 P43 external indicator

Setting-up procedure or centre mounted unit

Reer to drawings Nos, E.5468, E.5615 and schedule E.5468

1. Select position or indicator on tank wall. This will usually be on a manway ange or other

convenient point. I a P43 wall mounted installation is being used, the indicator can be

mounted on the same ange as the inlet pipework

I the installation is centrally mounted, the position o the indicator may be determined by other

actors such as the route o the exible drive (item 38).

The exible drive should be routed such that it runs past any available xtures inside the tank such

as the P43 inlet pipework or the water draw-o line. This will enable the drive to be secured once

the indicator has been set-up. The drive should not be run close to heating coils where these may be

used ater installation.

Keep the number o changes in direction o the drive to a minimum. The indicator will operatesatisactorily with up to six 90 bends.

When routing the drive, ensure that no part o it can be trapped or caught by roo legs or roo water

draw-o pipework when the roo is raised or lowered.

2. Cut a hole 80mm dia. in the manway ange to coincide with the centre lines o the indicator

3. Weld the studded ange (item 13) to the manway ange centrally around 80mm dia. hole

4. Feed end o the exible drive through the 80mm hole and bolt indicator to studded ange with

items (32) and (35), including gasket (item 10)

5. Bolt manway ange to tank taking care not to damage the exible drive

6. Run drive along the desired route to the P43

7. Bolt P43 to inlet pipework ange. Choose two adjacent bolts on the P43 mounting ange

or the attachment o the mounting bracket (item 15). These will normally be in line with the

direction o the drive as it meets the P43. Leave these two bolts undone and the others slack

8. Slide mounting bracket over the bolts in the position shown on the drawing and secure.

Tighten all P43 ange bolts ully

9. Slide sprocket end o exible drive onto the mounting bracket until the sprocket touches the

pins on the bearing plate (item 1). Secure with items (5), (17) and (33), using Loctite 241 adhesiveor equivalent to coat the bolt threads

Note that Figure 3.9 shows a wall mounted installation. For a central mounted installation,

the whole assembly at the P43 will be upside down

10. Secure the whole length o the exible drive to the xtures along its route with stainless steel

wire. ENSURE THAT THE DRIVE NEAR THE P43 IS CLEAR OF THE ROTATING NOZZLES

11. When the P43 is run, there will be a delay o about 20 minutes beore the indicator moves.

When the P43 is moving, the indicating disc (item 16) will rotate at the same speed as the

P43. By timing the rotation o the disc through one revolution or any given angle, the speed o

the P43 can be assessed


30/45


B. Maintenance

3.4 P43 lubrication

The gearbox is lubricated by EP 320 oil. This should be renewed at the periodic services.

3.5 Recommended operating level

The requency and duration o operation will depend on the rate o sludge deposition.

But it is strongly recommended that the P43 be run or an approximate ONE ROTATION

OF THE NOZZLE at least ONCE A MONTH to ensure ree movement o internal components.

3.6 External indicator

An external indicator can be supplied as an optional extra.

INDICATOR indicates nozzle movement

(FOR SHELL MOUNTED P43) and nozzle position

INDICATOR

(FOR CENTRE MOUNTED P43) indicates nozzle movement only

The indicating mechanism is mechanically connected to the P43. (See Figure 3.9).

3.7 Servicing interval

Following 15 years o installation, it is recommended that the P43 is removed or routine service,together with the external indicator (where tted). It should then be returned to Veolia or our

approved service centre or complete overhaul. A substitute unit can be supplied at the time the

existing unit is removed to minimize tank outage time.
