  • Disposal of waste gases from production of aluminum chloride
    Patent number: 4157374
    Abstract: Waste gases containing 15% or less vaporized chlorides are processed to recover chlorine values as HCl by filtration of particulate material followed by the adsorption of metal chlorides on carbon beds and subsequent hydrolyzing of the metal chlorides at a temperature of 100.degree.-150.degree. C. to form metal oxides and HCl. The remaining gases such as COCl.sub.2 are further hydrolyzed to recover aqueous HCl and then the gases are scrubbed and finally incinerated to provide a discharge to the atmosphere containing CO.sub.2, N.sub.2, H.sub.2 O, O.sub.2 and about 5ppm HCl.
