Abstract
A process for the HF-catalyzed alkylation of aromatic hydrocarbons is disclosed. A first overhead vapor stream removed from a first fractionation column which is used to regenerate the liquid-phase HF is passed directly into an upper intermediate point of a second fractionation column. A hydrocarbon stream containing the feed aromatic hydrocarbon and the product hydrocarbon is separated from liquid-phase HF and is then passed into the second fractionation column. HF dissolved in the hydrocarbon stream is removed from the second column as part of a second overhead vapor stream.
