摘要： Apparatuses and systems for removing heavy hydrocarbons from a solvent stream are disclosed herein. The apparatuses extract heavy hydrocarbons into light hydrocarbons and provide a solvent stream having the heavy hydrocarbons removed. Two water washing steps are used to remove residual solvent from the heavy hydrocarbon solution in light hydrocarbons. In some embodiments, the second water wash is used for processing subsequent batches of the solvent stream. The heavy hydrocarbons and solvent can be recovered and processed further. Methods for removing heavy hydrocarbons from a solvent stream are also disclosed herein.
