INTEGRATED H.F.REGENERATION IN AROMATIC HYDROCARBON ALKYLATION PROCESS

摘要

A process is disclosed for the production of alkylaromatic hydrocarbons by the HF catalyzed reaction of an aromatic hydrocarbon with a C8-plus acyclic olefin. A portion of the HF used as catalyst is regenerated by passage into a stripping column which has a primary function of stripping dissolved HF out of a hydrocarbonaceous mixture produced in the alkylation zone. This eliminates the requirement for a separate HF regeneration column and the costs associated with this column.
