ABSTRACT:
In the recovery of ethane and propane from an alkylation of an isoparaffin with an olefin to prevent buildup of ethane and propane in the system, the ethane and propane are taken as a side draw from the conventional HF stripper instead of being vented from the depropanizer or the fractionator overhead accumulator. Considerable ethane, propane and HF are thus saved and equipment costs reduced, especially because fractionator wall thickness can be reduced and because of the elimination of the equipment attendant the venting of the accumulator.
