MSPX //.Chapter 4. bowl function questionNo level ring!Why has the level ring been removedA level ring is not necessary in this separator //.Chapter 4. bowl function questionWhy has the water paring disc been replaced by a paring tube? To avoid generation of heat in separator top //.Chapter 4. bowl function //.Chapter 4. bowl function Product flow1. Alcap ? Valve V 5 normally closedConditioning water2. Oil flow ? Inlet ? Paring chamber3.Water / Sludge4. Paringtube position //.Chapter 4. bowl function Inside the bowl at discharge -1Dirty oil in ? Interface / separated sludgeIf back pressure increased? ? Oil level inwards ? Interface outwards ? Water level inwards ? Paring tube inwardsIf back pressure decreased? //.Chapter 4. bowl function Inside the bowl at discharge -2Feed offOil levelWater level //.Chapter 4. bowl function Inside the bowl at discharge -31 - Water outlet closed2 - Oil outlet closed ? opened at pressure increase signal from PT4 in oil outlet? 3 - Oil displaced ? Displacement volume based on calibration of water flow at first start-up. //.Chapter 4. bowl function Inside the bowl at discharge -4Displacement continuesParing tube moves in ? Oil column replaced by water - heavierComplete displacementTube flush //.Chapter 4. bowl function Inside the bowl at discharge -5After dischargeEmpty bowl //.Chapter 4. bowl function Inside the bowl at discharge -6Conditioning water is added , time is depending on calibration made at first start-up //.Chapter 4. bowl function Inside the bowl at discharge -7After conditioning waterTop disc well coveredWater does not reach disc stack //.Chapter 4. bowl function Inside the Inside the bowl bowl at at discharge -8 discharge -8Feed onWater pushed outOil does not pass top diskBowl in running condition //.Chapter 4. bowl function Oil Losses per day 100 90 MOPX 207 1hr 80 70 MOPX 207 2hr 4 lit/disch 60 4 lit/disch 50 LOPX 707 0.07 lit/disch 30min 40 0.5 lit/disch SU 300 2hr 30 0.7 lit/disch 20 SU 400 2hr 10 0 Oil Loss per day //.Chapter 4. bowl function Total Oily water sludge per day 350 MOPX 207 1hr 300 Vol/disch 250 MOPX 207 2hr 13 lit/disch 200 13 lit/disch LOPX 707 5 lit/disch 150 30min 6.2 lit/disch SU 300 2hr 100 7.4 lit/disch 50 SU 400 2hr 0 Oily water sludge/day //.Chapter 4. bowl function Total Oily water sludge per day 207 207 707 300 400 350 300 250 200 WATER 150 OIL 100 50 0 15% 15% 1.50% 8% 8.3 Oil % of total oily water sludge volume //.Chapter 4. bowl function Activity Using your notes, describe sequence at discharge to person next to you! //.Chapter 4. bowl function Oil/water back pressure, tube position, Appendix 4Previous separator models ? Increase oil back pressure increases water pressure ? FOPX, water indicating pressure increases when recirc holes in heavy phase paring disc become blockedSeparation unit ? when oil pressure is increased the water pressure decreases //.Chapter 4. bowl function Oil/water back pressure, tube position, Appendix 4Paring tube ? free to move between inner and outer limits //.Chapter 4. bowl function Oil/water back pressure, tube position, Appendix 4Water paring chamber ? Low oil back pressure ? gives a large diameter water ring //.Chapter 4. bowl function Oil/water back pressure, tube position, Appendix 4Water paring chamber ? High oil back pressure ? gives a small diameter water ring //.Chapter 4. bowl function Oil/water back pressure, tube position, Appendix 4Paring tube position ? large diameter gives high pressure ? tube out gives high pressure //.Chapter 4. bowl function Oil/water back pressure, tube position, Appendix 4Paring tube position ? small diameter gives low pressure ? tube in gives low pressure //.Chapter 4. bowl function S type separator //.Chapter 4. bowl function The operating mechanismQUESTION, how do we push the operating slide against the bowl body when there are no springs in the bowl? //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.Chapter 4. bowl function The operating mechanism //.
