Process for HF-catalyzed alkylation of aromatic hydrocarbons
Patent
·
OSTI ID:6607992
A process for the HF-catalyzed alkylation of aromatic hydrocarbons is disclosed. A liquid-phase alkylation zone effluent stream comprising product alkylaromatic hydrocarbon is passed into an intermediate point of a first fractionation column. A sidecut is removed from the first column at a higher intermediate point and passed into a sidecut stripping column. The bottoms stream of the sidecut stripping column contains the feed aromatic and about 4-10 mole percent paraffinic hydrocarbons and is recycled to the alkylation zone. The overhead vapor stream of the sidecut stripping column is passed into the first column to aid in fractionation.
