Hydrofluoric acid alkylation is a common technique for the production of high octane gasoline and LPG fractions such as n-butane/propane. Acid settlers and adsorbent beds are used to remove fluoride, but traces still manage to make it into the final product that is delivered to the consumer. When the fluorides, chlorides, and sulfur in the butane react, they can produce extremely corrosive acids such as hydrofluoric and hydrochloric acids. As a result, gas leaks can evolve from these corrosive effects and pushes the need to monitor concentrations of halides.
