1. A method for treating a wet hydrocarbon sludge stream comprising:
separating the wet hydrocarbon sludge stream into a gaseous separation stream, a first crude product stream, and a liquid separation stream using a separation vessel;
processing the gaseous separation stream in a flare gas recovery system;
separating the liquid separation stream into a surge drum gas stream, a first surge drum liquid stream, and a second surge drum liquid stream using a surge drum; wherein,
the surge drum is a three-phase separator that acts to separate the surge drum gas stream, the first surge drum liquid stream, and the second surge drum liquid stream, wherein the first surge drum liquid stream comprises water and the second surge drum liquid stream comprises C4+hydrocarbons, and wherein the surge drum is at an operating pressure of between 220-300 psig and an operating temperature of between 100-150° F.;
separating the second surge drum liquid stream into a stripper gaseous stream and a stripper liquid stream using a stripper system
wherein the stripper system is at an operating pressure of between 200-250 psig and an operating temperature of between 200-250° F.;
processing the surge drum gas stream and the stripper gaseous stream in a gas treatment unit utilizing a solvent; and
separating the stripper liquid stream into an aqueous process stream and a primary crude product stream using a wet hydrocarbon separation vessel.
