  • Waste minimization and product recovery process
    Patent number: 5840955
    Abstract: A process for the enhanced recovery of hydrogen cyanide (HCN) obtained from the reactor effluent of an ammoxidation reaction of propylene or isobutylene comprising passing the reactor effluent through a quench column, an absorber column, a first distillation column, a second distillation column, a cooler and a knock-out pot, wherein the improvement comprises contacting the vapor phase containing hydrogen cyanide with an aqueous stream.
    Type: Grant
    Filed: November 25, 1997
    Date of Patent: November 24, 1998
    Inventors: Edward J. Sockell, Joseph C. Sarna, Ali Kerr, Sanjay P. Godbole
  • Process for elimination of waste material during manufacture of acrylonitrile
    Patent number: 5457223
    Abstract: A process for the substantial or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.
    Type: Grant

  • Process for elimination of waste material during manufacture of acrylonitrile
    Patent number: 5288473
    Abstract: A process for the substantial or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing an organic compound(s) into said reactor at a location where the compound(s) reacts with substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, the organic compound is methanol which is introduced into the reactor at below its coking temperature.

  • AOG incinerator NO.sub.x emission control via NH.sub.3 injection
    Patent number: 4954323
    Abstract: A process and apparatus for the reduction of NO in combustion effluent comprising injecting NH.sub.3 into contact with the combustion effluents wherein the improvement comprising injecting the NH.sub.3 into the combustion effluent through a venturi used to connect the incinerator means which produces the combustion effluent to the cooling means which cools the combustion effluent prior to emission into the atmosphere.
