Abstract
Methods and systems for treating an oil/water vapor stream containing solids fines. Routing a feed composition of oil/water vapors containing fine solids to a condensing unit, combining the feed composition with a cooled OWS emulsion, forming a warmed OWS emulsion. The warmed OWS emulsion is routed to a surge vessel containing a volume of surge OWS emulsion, where after a first portion of the surge OWS emulsion is routed to a heat exchanger, forming the cooled OWS emulsion, and a second portion of the surge OWS emulsion is routed to an OWS separation unit. The OWS separation unit may be one or more disc stack centrifuges, in some cases preceded by one or more decanting centrifuges. In certain embodiments the oil/water vapor stream containing solids fines is generated from a thermal desorption unit, such as a turbulent vacuum thermal desorption unit. Systems may be integrated with thermal desorption units and drilling rigs.
