Using Karl Fischer Gas Analyzers to Identify Moisture in Liquefied Petroleum

Hydrofluoric acid alkylation units can contain moisture content, which must be tracked accurately. Also, to prevent acid dilution the feedstock of alkene, HF, and isobutene should be tracked for the presence of water, otherwise this may result in unwanted formation of polymer or oily samples.
