  • Patent number: 8784733
    Abstract: Chlorine dioxide generation systems and methods are disclosed. One or more reactants, such as sodium hypochlorite, may be electrolytically generated on-site for delivery to a reaction column. Low concentration reactants may be used to generate chlorine dioxide as part of a mixed oxy-chloro product stream containing free available chlorine. In at least one embodiment, an optical analyzer may be positioned along a reactant feed line to measure a concentration of reactant supplied to a reaction column. A controller may adjust a flow rate of the reactant in response to information provided by the optical analyzer. The controller may also perform pH control within the system. In some embodiments, the chlorine dioxide generator may be incorporated in an all-liquid water disinfection system.

  • Patent number: 8721842
    Abstract: A catalytic reaction-rectification integrated process and a catalytic reaction-rectification integrated column, and the specialized device of such process is provided. The reactants are preheated and mixed with catalysts, and then fed into a jet agitation reaction section located in the middle of the catalytic reaction-rectification integrated column from a feeding inlet. The jet agitation reaction section is a kettle-like reactor located in the middle of the catalytic reaction-rectification integrated column. After pressurized by a centrifugal pump, the reactant materials are admitted into a subsonic or transonic agitator located within the reaction section. The reactant materials are ejected into the jet agitation reaction section at high speed, to efficiently mix the solid and liquid phases in the reaction section and to reinforce heat and mass transfer efficiency during the reaction. The liquid reaction mixture is separated and purified directly in the catalytic reaction-rectification integrated column.
