  • Waste disposal process
    Patent number: 4549985
    Abstract: Method for precipitating and removing soluble metal compounds from solutions of phosphoric acid. The method is useful in the disposal of metal-containing phosphoric acid waste from electrolytic operations, including such acid solutions contaminated with uranium compounds.
    Type: Grant
    Filed: June 7, 1982
    Date of Patent: October 29, 1985
    Assignee: General Electric Company
    Inventor: Henry H. Elliott
  • Method for metal halide removal
    Patent number: 4544379
    Abstract: A method for removing metal halides from effluent gas streams employs a rotary spray scrubber including an elongate gas flow duct and a rotary scrubber dispersion hub. The rotary spray scrubber is characterized by a ratio of hub diameter to duct diameter in the range from about 0.55 to 0.75. Using a basic liquid scrubbing medium in such a scrubber, metal halide particulate and hydrochloric acid gas removal efficiencies in excess of 99% have been achieved.
