Abstract
A method for removing organic fluorides from HF alkylation propane in which a stream of relatively pure liquid HF obtained by settling liquid HF from the liquefied hydrocarbon passed to the overhead accumulator common for both the depropanizing column and a hydrogen fluoride stripping column is intimately contacted with a stream of liquid hydrocarbon containing organic fluorides derived from condensing the mixed overhead vapor from a depropanizing column and overhead vapor from an HF stripping column in the process of separating products from a hydrogen fluoride alkylation. In preferred embodiments, the contacting takes place in the static mixer.
