ABSTRACT:
A process for the alkylation of an aromatic hydrocarbon with an olefinic hydrocarbon wherein a gaseous catalyst promoter is circulated through the alkylation zone effluent separation equipment including a first fractionation column. Part of the motive force for this promoter circulation is derived from depressurizing the vaporous phase of the alkylation zone effluent through an ejector which draws a suction on the overhead receiver of the fractionation column.
