Abstract

A closed-loop process for incinerating chlorinated hydrocarbon-containing material without the emission of air borne pollutants. The chlorinated hydrocarbon-containing material is incinerated, preferably in the substantial absence of air, thereby producing a gaseous effluent containing hydrogen chloride and pollutants such as carbon dioxide, acid gases, and halogenated compounds. The gaseous effluent is passed through a hydrogen chloride purification system to remove hydrogen chloride from the gaseous effluent and to produce a concentrated anhydrous hydrogen chloride gaseous stream. The gaseous effluent is passed through at least one sorbent bed, such as a bed of activated carbon, to remove halogenated pollutants from the effluent. The pollutants are desorbed from the one or more sorbent beds and recycled to the incinerator where they are decomposed by combustion.
