Referring then to the drawing, there is shown an isostripper column 3. The isostripper column is typically operated at fractionation conditions including a bottom temperature of from about 350° to about 390° F., a top temperature of from about 125° to about 150° F., a bottom pressure of from about 155 to about 165 psig., and a top pressure of from about 145 to about 155 psig. In the present example, an alkylation reaction zone effluent stream, at a temperature of about 100° F., is charged to a heat exchanger 2 contained in line 1 whereby said stream is heated to a temperature of about 150° F. by indirect heat exchange with the hot alkylate product stream recovered from the isostripper column by way of line 27. The alkylation reaction zone effluent stream is continued through line 1 to provide about 271.4 moles of propane, 2721.4 moles of isobutane, 649.9 moles of n-butane, 29.4 moles of isopentane, 1.3 moles of n-pentane and about 394.6 moles of C6 + hydrocarbons per hour to the isostripper column 3. Said alkylation reaction zone effluent stream further contains about 125.7 moles of HF per hour, the mole quantities expressed herein being intended as lb-moles.
