Abstract

1440008 Combustion of chlorine containing material; HCl recovery HOECHST AG 20 Dec 1973 [22 Dec 1972] 59118/73 Heading C1A Chlorine-containing organic material is (a) burnt at 600-1500‹ C. in a combustion zone in the presence of excess air while introducing azeotropic hydrochloric acid into the zone, (b) the combustion gases are washed with azeotropic hydrochloric acid to absorb HCl gas contained in these gases and yield more concentrated hydrochloric acid, (c) HCl gas and azeotropic hydrochloric acid are recovered from this more concentrated acid, and (d) the azeotropic acid recovered in step (c) is recycled to steps (a) and (b).
