ABSTRACT:
The normal paraffin feed stream to an integrated paraffin isomerization-HF acid-catalyzed alkylation process is treated for the removal of catalyst deactivating sulfur and nitrogen compounds and water by contacting the feed stream with liquid hydrofluoric acid. The treated feed stream is separated from the acid by gravity settling, charged to an alkylate fractionator, and passed through the isomerization process to form an isomerate which is returned to the alkylate fractionator and becomes a feed stream to the alkylation zone.
