Abstract
A method can include: in a heat exchanger, cooling a biocrude oil emulsion stream received from a biocrude oil emulsion source, wherein the emulsion can include a biocrude oil phase, an aqueous phase, and solids; in a first mixing vessel, mixing the emulsion with a solvent to dissolve the biocrude oil phase and form a biocrude-solvent solution; in a first separator assembly, separating the biocrude-solvent solution from the aqueous phase and the solids; in a solvent recovery apparatus, recovering solvent from the biocrude-solvent solution; in a second mixing vessel, mixing the solvent with the aqueous phase and the solids received from the first separator assembly to dissolve biocrude oil remaining in the aqueous phase and the solids; and supplying the solvent and biocrude oil to the first mixing vessel as the solvent. In some examples, such a method can more effectively separate biocrude oil from the emulsion than conventional techniques.
