  • Multi-stage process for reducing the concentration of pollutants in an effluent
    Patent number: 5057293
    Abstract: A process is presented for reducing the concentration of pollutants in an effluent from the combustion of a carbonaceous fuel. The process comprises introducing a first treatment agent into the effluent at a first temperature zone to reduce the concentration of a first pollutant and introducing a second treatment agent into the effluent at a second temperature zone to reduce the concentration of either the first pollutant or a second pollutant, wherein the first and second treatment agents are introduced under conditions effective to reduce the effluent pollution index.
    Type: Grant
    Filed: May 23, 1989
    Date of Patent: October 15, 1991
    Assignee: Fuel Tech, Inc.
    Inventors: William R. Epperly, Jeremy D. Peter-Hoblyn, George F. Shulof, Jr., James C. Sullivan, Barry N. Sprague, John H. O'Leary
  • Multi-stage process for reducing the concentration of pollutants in an effluent using an ammonium salt
    Patent number: 4863704
    Abstract: A process is presented for reducing the concentration of pollutants in an effluent from the combustion of a carbonaceous fuel. The process comprises injecting a first treatment agent into the effluent at a first temperature zone and injecting a second treatment agent into the effluent at a second temperature zone, wherein the first and second treatment agents are injected under conditions effective to reduce the effluent pollution index. At least one of the treatment agents comprises an ammonium salt of an organic acid having a carbon to nitrogen ratio of greater than 1:1.
