Abstract
The reaction product effluent emanating from an isoparaffinic/olefinic, HF-alkylation reactor system, containing normal paraffins, motor fuel, alkylate, unreacted isoparaffins, hydrogen fluoride catalyst and organic fluoride compounds, is separated to recover a motor fuel alkylate product substantially free from fluoride compounds, and having a predetermined volatility, or vapor pressure. Two separation zones are employed to produce an alkylate containing hydrogen fluoride and a normal paraffin stream containing organic fluoride and hydrogen fluoride. Three treating zones afford the recovery of a fluoride-free motor fuel alkylate and a fluoride-free normal paraffin concentrate; a portion of the latter is blended with the former to adjust the volatility to the predetermined level.
