  • Method of forming a sidewall for a reactor for oxidizing volatile or semi-volatile organic compounds
    Patent number: 5979054
    Abstract: A method of forming a sidewall for a reactor for oxidizing volatile or semi-volatile organic compounds, the sidewall being reactive with gaseous oxidation products produced by the oxidation of the volatile or semi-volatile organic compounds, includes, i) providing a dry mixture of material comprising by weight: from about 23% to 35% cement; from about 30% to 45% added CaO; from about 6% to 20% added Ca(OH).sub.2 ; and from about 10% to 25 % added CaSO.sub.4 ; ii) combining the dry mixture of material with water and forming a slurry therefrom; iii) forming the slurry into a desired reactor sidewall shape; and iv) hardening the shaped slurry into a hardened cement reactor sidewall.
    Type: Grant
    Filed: September 24, 1997
    Date of Patent: November 9, 1999
    Assignee: Process Technologies, Inc.
    Inventors: Theodore S. Weigold, Adam J. Regner, III, John D. Ferrell
  • Method and apparatus for use in photochemically oxidizing gaseous volatile or semi-volatile organic compounds
    Patent number: 5707595
    Abstract: A method of forming a sidewall for a reactor for oxidizing volatile or semi-volatile organic compounds, the sidewall being reactive with gaseous oxidation products produced by the oxidation of the volatile or semi-volatile organic compounds, includes, i) providing a dry mixture of material comprising by weight: from about 23% to 35% cement; from about 30% to 45% added CaO; from about 6% to 20% added Ca(OH).sub.2 ; and from about 10% to 25% added CaSO.sub.4 ; ii) combining the dry mixture of material with water and forming a slurry therefrom; iii) forming the slurry into a desired reactor sidewall shape; and iv) hardening the shaped slurry into a hardened cement reactor sidewall. An apparatus for photochemically oxidizing gaseous volatile or semi-volatile organic compounds includes a reactor vessel comprising sidewalls having at least one baffle.
