Abstract
In an HF alkylation process the HF phase leaving the reaction zone is introduced into a separate resaturation zone wherein this HF phase is contacted with isobutane to resaturate the HF with isobutane. In the main hydrocarbon fractionator only a very small quantity of isobutane has to be evaporated and this isobutane can be withdrawn as a side stream and recycled.
