ABSTRACT:
The overhead stream of a deisobutanizer in an HF-alkylation plant is extracted with HF to produce a stream containing isobutane, HF and ethyl fluoride, which in turn is fractionated under a pressure of about 150 to 300 psig. The bottoms stream of this fractionation, then, is fractionated under a pressure of 50 to 145 psig to produce a relatively pure ethyl fluoride overhead stream and a relatively pure HF bottoms stream.
