Abstract

1429909 HCI, Cl 2 removal from gas streams; recovery of chlorine values from polymers LUMMUS CO 19 June 1974 [20 June 1973] 27228/74 Heading C1A Chlorine values are recovered from a solid waste which contains chlorinated polymers by (a) incinerating the waste to produce a gaseous incineration effluent containing HCl or a mixture of HCl and Cl 2 ; (b) contacting the effluent gas with a molten mixture of the higher and lower chlorides of a multivalent metal and its oxychloride whereupon the chlorine content of the molten mixture is increased, and (c) recovering chlorine values from said molten mixture; the incineration effluent is then essentially free of the gaseous chlorine values. In one preferred embodiment, the chlorinated polymers are polyvinylidene chloride, polyvinyl chloride or polychloroprene, while the molten mixture of chlorides comprises CuCl 2 , CuCl and CuO.CuCl 2 . Recovery of the chlorine values from the chlorine-enriched melt may be effected by contacting it with a hydrocarbon to produce a chlorinated hydrocarbon; additional free HCl and/or chlorine may be used in this process.
