Environmental safety apparatus for airborne hydrogen fluoride recovery and method

摘要

A safety apparatus has been found for recovering an airborne hydrogen fluoride release in a hydrocarbon alkylation process. The safety apparatus comprising containment baffles and hydrogen fluoride detectors. Hydrogen fluoride detectors activate water flood means which discharge into the containment baffles. The water flood containing essentially all of the hydrogen fluoride release is recovered for disposal. Recoveries of 90 wt % have been demonstrated.
