ALKYLATION PROCESS WITH SETTLER EFFLUENT RECYCLE

摘要

A system and/or process for increasing the isobutane to olefin ratio in an alkylation process/system (10) is disclosed. The system and/or process includes provisions for charging a portion of the settler effluent (119) as a feed (123, 125) to at least one reaction zone (101b) downflow from the first reaction zone (101a) of a multi-zone alkylation reactor (101) along with a portion of the olefin feed to the multi-zone alkylation reactor.
