  • Patent number: 11179654
    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.

  • Patent number: 9939197
    Abstract: Feeding a slurry comprising inert solids, liquid hydrocarbons, liquid water and sometimes dissolves solids to a unit having a casing defining a thermal extraction chamber heated both directly and indirectly in which first and second intermeshing screws rotate, the screws in close tolerance with each other and with inside casing surfaces. The casing and screws define a tortuous flow path in which the slurry and a vaporous composition evolved therefrom flow. The intermeshing screws push the slurry toward a discharge end of the chamber at a first velocity while reducing pressure and increasing temperature in the chamber, while rotating the screws to create turbulent vacuum thermal conditions in the chamber to physically transform some or all of the slurry into the vaporous composition. The vaporous composition traverses the tortuous flow path with a second velocity at least 1.5 times the first velocity, optionally forming a heated, substantially dry, composition comprising the inert solids.
