  • Automated method for controlling the rate of chlorine dioxide generation
    Patent number: 5382520
    Abstract: An automated process for controlling the rate chlorine dioxide made from sodium chlorate-chloride and sulfuric acid is generated. The process automatically adjusts the rate of chlorine dioxide production to the needs of the system treated with chlorine dioxide by controlling the feed of one or more of the reactants by means of a multiple feed-back loop system which provides adequate oxidative treatment while avoiding overfeed or underfeed conditions.
    Type: Grant
    Filed: July 14, 1993
    Date of Patent: January 17, 1995
    Assignee: Drew Chemical Corporation
    Inventors: Dale A. Jenson, Sam F. Eltomi
  • Method of producing chlorine dioxide in a gaseous stream and apparatus therefor
    Patent number: 5258171
    Abstract: The invention relates to a method and apparatus for generating chlorine dioxide in a reaction medium comprising a flowing gaseous carrier stream thereby providing chlorine dioxide having a low water content for use in oxidizing treatment applications which are sensitive to water. The method of the invention uses a mineral acid, such as hydrochloric acid, a hypochlorite salt, such as sodium hypochlorite salt and a chlorite salt, such as sodium chlorite salt, as reactants for generating ClO.sub.2. Air is the preferred gaseous carrier stream.

  • Method and apparatus for controlling the rate of chlorine dioxide generation
    Patent number: 5227306
    Abstract: A method and apparatus for the automatic control of oxidative treatment of material with chlorine dioxide. The method and apparatus of the invention automatically adjust the amount of chlorine dioxide applied to the system being treated by a multiple feed-back loop system to provide adequate oxidative treatment while avoiding overfeed or underfeed conditions.
