  • Recovery of elemental sulfur from sulfur dioxide bearing waste gases
    Patent number: 3969492
    Abstract: Process for effecting the selective removal of sulfur dioxide values from industrial waste gases or the like and conversion thereof to elemental sulfur wherein a particularly constituted solution of mixed ammonium phosphates is exposed to absorbent contact with the sulfur dioxide bearing gas stream followed by recovery of the sulfur values therefrom and regeneration of the absorbent solution preparatory to reexposure thereof to the sulfur dioxide bearing gas stream.
    Type: Grant
    Filed: October 29, 1973
    Date of Patent: July 13, 1976
    Assignee: U.S. Filter Corporation
    Inventors: Michael Witte, Manankumar S. Mehta
  • Electrostatically enhanced removal of sulfur dioxide from gaseous carriers
    Patent number: 3960687
    Abstract: Closed circuit process for effecting the selective removal of sulfur dioxide values from industrial waste gases or the like wherein a particularly constituted confined solution of mixed ammonium phosphates is exposed to absorbent contact with a sulfur dioxide bearing gas stream in an electrostatic force field followed by a thermally induced desorption of recoverable sulfur dioxide values therefrom and regeneration of the solution preparatory to reexposure thereof to the suflur dioxide bearing gas stream.
