Equipment Operation22. Operation2.1 Operating specificationsDuring the normal operating sequence of the P43®, there will be external circumstances whichwill lead to a change in the normal flow rate and/or supply pressure. These changes will alter thecleaning radius of the P43® and could affect the overall effectiveness of the P43® installation.The graphs (Figures 2.1 to 2.4) enable the operator to calculate the impact of these changeson cleaning radius, and which remaining parameters would need to be altered to restore theinstallation to its normal operational effectiveness.EXAMPLE:In the case of a 260' (79m) diameter tank with three P43®(s) at equidistant positions around thecircumference of the tank, the following applies:For a 100mm nozzle from Figure 2.3 and Figure 2.4:CASE ‘A’Range Flow Pressure drop across P43®130' (39.5m) 3375 IGPM (921m 3 /hr) 83 psi (5.8kg/cm 2 )CASE ‘B’Should the flow be reduced to 3000 GPM (819m 3 /hr) Then from Figure 2.4:Range115′ (35m)CASE ‘C’Should the pressure be reduced by 5psi then (from Figure 2.3) the pressure drop across the P43® willreduce to (83-5) = 78 psi (5.48kg / cm 2 ).Range126′ (38.4m)2.2 Recommended operating intervalIt is strongly recommended that the P43® is run at least once per month to prevent sludge build-upand to ensure free movement of internal components. The frequency and duration of operationwill be a function of sludge deposition rates, but in general should be about 8 sweeps per nozzle ina month.2 Equipment Operation1

MONITORING P43® EFFECTIVENESSA tank monitoring procedure should be devised to• Determine the crude oil quality for selection of processing strategy• Measure the effectiveness of blending• Determine the rate and effectiveness of sludge re-suspension2.3 Use of shell mounted P43® to de-sludge tank(i)(ii)Take samples of sludge and measure:B S & W (Bottom Sediment and Water)Conduct sludge profile survey across the tankEstimate sludge quantityEmpty tank and fit P43® (see Section 3.3)(iii) Fill storage tank with crude oil to a minimum height such that the roof is floatingIt is advantageous to have a large volume of crude to disperse the sludgeA ratio of approximately 4:1 (crude to sludge) is usually sufficient(iv)(v)(vi)If a minimum level of crude has been used, raise roof legs to their operating position tominimise jet disturbance during cleaning operation. Alternatively fill the tank to a levelwhere the roof legs are above the centre line of the jetSample the crude oil after filling the tank and measure B S & W levelsGradually increase the pressure to each P43® until the designated rate is achieved(vii) For the tank cleaning operation, we recommend a minimum of eight sweeps per P43®. Thistime can be reduced if the customer is prepared to stop the operation, allow a 1-hour settlingtime and conduct sludge profile measurements. If the levels are satisfactory then the operationcan be stopped(viii) When the operation is stopped to assess sludge profiles, it is recommended that samples aretaken at the top, middle and bottom to determine B S & W levelsThis data will give you useful information on the operating characteristics of the P43® and willassist in assessing the processing needs of this mixture(ix) If sludge is still present in the tank and the B S & W level exceeds 15% in the bulk of thecrude oil, we recommend draining the tank and adding fresh crude oil for a further periodof P43® operationNOTE: SEQUENTIAL OPERATIONIf the refinery is limited for flow 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,therefore, be extended.Heating of the oil is also an advantage when de-sludging, with 60ºC the maximumrecommended temperature.2 Equipment Operation6

2.4 Procedure for processing sludge dispersed in crude oilThe sludge dispersed in the crude oil mixture may need to be blended in line with the feedstockfrom a neighbouring tank. The decision on the exact percentage of the blend should be based onthe composition of the sludge / crude oil mixtures. If the P43® has been used to de-sludge the tankwith a minimum crude level, then a blend of 5 to 10% could be required.The following parameters should be monitored to assess any downstream impacts:(i)B S & W and salt levels in the inlet and outlet of the desalterIn order to assess the fouling tendencies of the crude oil, monitor(i) Pressure drops across crude pre-heat exchangers before, during and after sludge /crude oil processing(ii)Overall heat transfer coefficients (‘U’ Values) across crude preheat exchangers,before, during and after sludge / crude oil processing2.5 Routine check on P43® operationIt is recommended that the following 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 pressurefor the installation• Monitor line filter pressure drop to ensure that the line filter is not blocked• During P43® operation, check indicator (where fitted) for correct P43® rotation2.6 Special considerationsIf 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 of the P43® and vicinity elevated• Checking that the strainer(s) is clear• Checking the indicator (where fitted) to ensure the P43® is rotating• Checking the pressure and flow rate on starting against figures given for the installationsand/or previous results (see Figures 2.1 to 2.4)• Ensuring that the supply line to the P43® is drained / empty if the heat is to beswitched off2 Equipment Operation7

Installation andMaintenance3A. Installation3.1 Equipment suppliedVeolia provide only the P43®, which is filled with oil and ready to be mounted onto the appropriatesupporting pipework. The P43® is fitted with an 8 inch ANSI flat face mounting flange and iscomplete with fixing bolts, mating flange and an earthing strap.The P43® is supplied as a sealed unit. Breakage of this seal will invalidate warranty.Veolia do NOT provide any of the associated pipework, supports, valves, gauges etc. However we willgive technical advice on the installation and comment on any piping proposals.Schematics for typical pipework required for installation of the P43® are illustrated on thefollowing pages.Prior to installation of the P43® in any tank, full regard must be given to safety procedures to ensurethe protection of all personnel. All standard safety procedures as laid down by governmental bodies,safety organizations and the operating company must be complied with.3.2 External pipework details3.2.1 Details for centre mounted P43®A schematic of the pipework is illustrated on Figure 3.3. The following should also be consideredwhen designing the system:• .Pipe diameter to be selected to ensure that the desired pressure at the P43® can be achieved• Line Supports. See Figure 3.6• P43® mounting flanges are 8 inch ANSI B.16.5 and have been designed toAPI 650 standard• In-line strainer specification – see Figure 3.3Material – stainless steelScreen size – diamond-shaped preventing a particle sizegreater than 19mm (3/4") from passingIt is recommended that the strainer is of a ‘basket’ type design to facilitate cleaning.3 Installation and Maintenance1

NOTE: It is possible that sufficient strainers may have been fitted at the pumps, thus makingthe fitting of a further strainer unnecessary.• All new pipework must be flushed through before commissioning in order to clear anydebris that may have accumulated during installation. The use of temporary strainersduring commissioning is also recommended• Ensure centre line of jet does not directly impinge on internal piping, e.g. stream coils,water draw-off, etc• Ensure also that all specified alterations to internal pipework have been completed• Line vents for commissioning should be included• Pressure gauges are fitted to measure P43® inlet pressure and identify if line filteris blocking. These should be upstream and downstream of the line filter• Valve requirement. See Figure 3.4• P43® supports to withstand jet reaction quoted by Veolia• Fabrication of elbow assembly to facilitate P43® installation. See Figure 3.4• Minimum distance between vertical centre line of P43® and inside of tank wellshould be *500mm for the P43® with standard nozzle attachments• Recommended clearance under the P43® 125mm• Inlet flange designed to A.P.I 650 hence bolt holes straddle the centre line of the P43®• Correct P43® orientation is indicated by a groove included on the main stationary component.This groove marks the centre line of the P43® and should be directed at the centre of the tank• When steam coils are present, P43® must be positioned such that nozzle discharges belowsteam heating coils*This measurement should be increased to 800mm for P43®(s) with ‘S’ Bend Nozzle tube attachments(see Section 4 Page 13).3 Installation and Maintenance2

3.3 System installation commissioningThe following 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 designspecification). Ensure that the impeller in the inlet to the P43® is free to rotate (by hand)b) Ensure by observing the centre line position of the nozzle that there will be no direct jetimpingement on internal piping e.g. stream coils, water draw-off etc. Also that all specifiedalterations to internal pipework have been completedc) To prevent impeller fouling on start-up, ensure that the lines feeding the P43®(s)(downstream from the line filter) have been flushed to remove scale deposits, welding rods etc.prior to installing the P43®(s). The use of a temporary strainer during commissioning is tobe recommendedd) Ensure that a pressure gauge 0-20 kg/cm² (0-300 psi) has been installed in the line betweentank shell and valve to measure P43® inlet pressuree) Fit gasket between the P43® and the saddle support and tighten bolts securely. Check the planeof the nozzle rotation to ensure that it is free from obstruction, and the centre line of the jetdoes not directly impinge on tank internalsf) The P43® is electrically continuous. To ensure electrical continuity with the pipework anearthing strap is supplied. This should be used to bond the inlet flange on the P43® to the pipeassembly. When assembled the whole surface of the strap and the fasteners should be coatedwith an oil resistant paintg) Ensure that the external indicator (where fitted) is in place and the flexible drive issecurely fastenedh) After line commissioning, gradually increase the pressure to the P43® until the designed rateis achievedi) Monitor the position of the P43® on the external indicator after half an hour operation andrecord the position after a further half an hour period to ensure that the P43® is rotating freely.Check the rotation rate of the P43® and ensure that it is within 10% of the specified time for therotation at the design pressure3.3.2 Shell mounted P43® (for manways 30” or greater)a) Check that the correct nozzle size has been installed (i.e. in accordance with designspecification). Ensure that the impeller in the inlet to the P43® is free to rotate (by hand)b) Ensure by observing the centre line position of the nozzle that there will be no direct jetimpingement on the internal piping e.g. steam coils, water draw-off etc. Also that all specifiedalterations to internal pipework have been completedc) To prevent impeller fouling on start-up, ensure that the lines feeding the P43®(s) (downstreamfrom the line filter) have been flushed to remove scale, deposits, welding rods, etc. prior toinstalling the P43®(s)d) Assemble P43® into inlet pipe fabrication together with gate valve and non-return valve,see Fig. 3.4e) NOTE: that the centre line of the P43® is marked by a machined slot. This slot must point tothe centre of the tankf) Check that the earthing strap is fixed across the flanges and is making a good contact and hasbeen painted3 Installation and Maintenance10

3.3.4 P43® external indicatorSetting-up procedure for centre mounted unitRefer to drawings Nos, E.5468, E.5615 and schedule E.54681. Select position for indicator on tank wall. This will usually be on a manway flange or otherconvenient point. If a P43® wall mounted installation is being used, the indicator can bemounted on the same flange as the inlet pipeworkIf the installation is centrally mounted, the position of the indicator may be determined by otherfactors such as the route of the flexible drive (item 38).The flexible drive should be routed such that it runs past any available fixtures inside the tank suchas the P43® inlet pipework or the water draw-off line. This will enable the drive to be secured oncethe indicator has been set-up. The drive should not be run close to heating coils where these may beused after installation.Keep the number of changes in direction of the drive to a minimum. The indicator will operatesatisfactorily with up to six 90° bends.When routing the drive, ensure that no part of it can be trapped or caught by roof legs or roof waterdraw-off pipework when the roof is raised or lowered.2. Cut a hole 80mm dia. in the manway flange to coincide with the centre lines of the indicator3. Weld the studded flange (item 13) to the manway flange centrally around 80mm dia. hole4. Feed end of the flexible drive through the 80mm hole and bolt indicator to studded flange withitems (32) and (35), including gasket (item 10)5. Bolt manway flange to tank taking care not to damage the flexible drive6. Run drive along the desired route to the P43®7. Bolt P43® to inlet pipework flange. Choose two adjacent bolts on the P43® mounting flangefor the attachment of the mounting bracket (item 15). These will normally be in line with thedirection of the drive as it meets the P43®. Leave these two bolts undone and the others slack8. Slide mounting bracket over the bolts in the position shown on the drawing and secure.Tighten all P43® flange bolts fully9. Slide sprocket end of flexible drive onto the mounting bracket until the sprocket touches thepins on the bearing plate (item 1). Secure with items (5), (17) and (33), using Loctite 241 adhesiveor equivalent to coat the bolt threadsNote that Figure 3.9 shows a wall mounted installation. For a central mounted installation,the whole assembly at the P43® will be upside down10. Secure the whole length of the flexible drive to the fixtures along its route with stainless steelwire. ENSURE THAT THE DRIVE NEAR THE P43® IS CLEAR OF THE ROTATING NOZZLES11. When the P43® is run, there will be a delay of about 20 minutes before the indicator moves.When the P43® is moving, the indicating disc (item 16) will rotate at the same speed as theP43®. By timing the rotation of the disc through one revolution or any given angle, the speed ofthe P43® can be assessed3 Installation and Maintenance14

B. Maintenance3.4 P43® lubricationThe gearbox is lubricated by EP 320 oil. This should be renewed at the periodic services.3.5 Recommended operating levelThe frequency and duration of operation will depend on the rate of sludge deposition.But it is strongly recommended that the P43® be run for an approximate ONE ROTATIONOF THE NOZZLE at least ONCE A MONTH to ensure free movement of internal components.3.6 External indicatorAn external indicator can be supplied as an optional extra.INDICATOR(FOR SHELL MOUNTED P43®)INDICATOR(FOR CENTRE MOUNTED P43®)indicates nozzle movementand nozzle positionindicates nozzle movement onlyThe indicating mechanism is mechanically connected to the P43®. (See Figure 3.9).3.7 Servicing intervalFollowing 15 years of installation, it is recommended that the P43® is removed for routine service,together with the external indicator (where fitted). It should then be returned to Veolia or ourapproved service centre for complete overhaul. A substitute unit can be supplied at the time theexisting unit is removed to minimize tank outage time.3 Installation and Maintenance15
