Abstract
A process is presented for the recovery of solvent used in an alkylation process. The solvent removes heavy hydrocarbons from a C4 stream. The C4 stream is passed to an alkylation unit to generate an alkylate product. A portion of the solvent is carried over with the C4 stream and needs to be recovered to reduce the aromatics content in the C4 stream, to reduce any deleterious effects of the aromatics in downstream processing.
