Offshore pollution prevention
Patent
·
OSTI ID:6840222
A complete system for removing oil from produced water and deck drain fluids in an offshore facility includes a surge settler which receives the produced water from a three-phase separator. In the surge settler, the produced water flows crosswise through a corrugated plate assembly to separate free oil and solids from the produced water. A portion of the produced water which is relatively free of solid particles (less than 50 microns) is then treated in a water washer with a portion which is relatively rich in solid particles further treated in a solids cleaner. In the water washer 90% or more oil droplets (less than 50 microns) is removed from the produced water and the relatively oil free water is then disposed by way of a skim pile. A portion of fluid from the water washer is further treated in a high efficiency skimmer. In the solids cleaner a conical corrugated plate arrangement having periodic agitation by sand cleaning eductors removes free oil from the solids rich portion of the fluid which is relatively rich in solid particles and passes a relatively oil free and solids rich portion to a skim pile for disposal. Drained fluids from exposed decks and elsewhere are supplied directly to the skim pile for oil removal prior to passage into the surrounding body of water.
