Abstract
The invention provides a substantially fail-safe HF alkylation process and reactor apparatus. The elongated reactor vessel is enclosed in a subterranean well casing and an alkylate-containing hydrocarbon layer is maintained above the hydrofluoric acid to prevent release of gaseous HF in the event of sudden depressurization. In a preferred embodiment, the hydrocarbon layer contains light hydrocarbons which vaporize upon depressurization to effect Joule-Thompson cooling of the reactor vessel.
