Abstract
Hydrogen contamination of chlorine-containing gas, such as the chlorine gas from the electrolytic chlorine/caustic process and especially the tail gas from the chlorine liquefaction operation, is eliminated by reaction of the hydrogen directly in the gas mixture at elevated temperature in the presence of a catalyst, to effect combination of the hydrogen with chlorine to form hydrogen chloride, followed by scrubbing of the hydrogen chloride from the gas.
