  • Continuous process and apparatus for purifying SO2-containing gases
    Patent number: 10376834
    Abstract: The invention relates to a continuous process for purifying a gas containing 60-99 percent SO2 (sulfur dioxide) by volume and 1 to 40 percent steam by volume, followed by synthesis of SO3 (sulfur trioxide) without first drying the gas, and to an apparatus for carrying out said method.
    Type: Grant
    Filed: March 29, 2016
    Date of Patent: August 13, 2019
    Assignee: CHEMETICS INC.
    Inventors: Torsten Weber, Bernd Erkes, Lucia Fernandez Lopez

  • Process and apparatus for the catalytic oxidation of SO-containing gases by means of oxygen
    Patent number: 7871593
    Abstract: Process for the continuous catalytic complete or partial oxidation of a starting gas containing from 0.1 to 66% by volume of sulphur dioxide plus oxygen, in which the catalyst is kept active by means of pseudoisothermal process conditions with introduction or removal of energy; apparatus for the continuous catalytic complete or partial oxidation of a starting gas containing sulphur dioxide and oxygen having at least one tube contact apparatus in the form of an upright heat exchanger composed of at least one double-walled tube whose catalyst-filled inner tube forms a reaction tube, with heat being transferred in cocurrent around the reaction tube and an absorber for separating off SO3 downstream of the tube contact apparatus; the reactivity of the catalyst being preset by mixing with inert material.
    Type: Grant
