Abstract
The reactor effluent hydrocarbon phase from an alkylation zone in which isoparaffin and olefin are contacted in the presence of HF catalyst to form an alkylate product is treated by (1) separating a hydrocarbon phase from the reacton effluent; (2) separating the hydrocarbon phase in a fractionator to produce a bottoms stream containing isoparaffin, paraffin, and alkylate and an overhead stream containing HF, isoparaffin, and paraffin; (3) flashing this bottoms stream to produce a flashed vapor enriched in isoparaffin and a liquid enriched in alkylate as compared to the bottoms stream; (4) cooling this flashed vapor to produce a condensed liquid; and (5) indirectly contacting this condensed liquid with the overhead stream thereby cooling the overhead stream and heating the condensed liquid. In further embodiments of the invention flashing the condensed liquid thereby producing (a) a flashed vapor further enriched in paraffin which is then compressed and further treated to remove residual isoparaffin and (b) a liquid further enriched in isoparaffin which is recycled to the alkylation zone. In another embodiment of the invention the overhead stream is condensed by contact with the condensed liquid, pumped into contact with HF thereby removing organic fluorides, and is then subjected to treatment effecting separation of paraffin from isoparaffin.
