  • Method and apparatus for producing a fertilizer from gas containing sulfur oxides
    Publication number: 20020088261
    Abstract: The present invention relates to a method and an apparatus for producing a fertilizer by injecting ammonia into and applying electron beam to gas containing sulfur oxides. Gas containing sulfur oxides is cooled by a heat exchanger (2) and a cooling tower (3), and thereafter introduced into a process vessel (4) in which ammonia is injected into the gas and the gas is irradiated with electron beam. The product of the ratio of the concentration of ammonia to the concentration of water in the gas prior to irradiation of the electron beam and the ratio of the concentration of ammonia to the concentration of water in the gas after irradiation of the electron beam is controlled to be of a predetermined value.
    Type: Application
