  • Device and process for producing hydrogen peroxide by an anthraquinone process
    Patent number: 11912571
    Abstract: In a cyclic anthraquinone process for producing hydrogen peroxide, which comprises a distillation unit with vapor compression for concentrating hydrogen peroxide, aqueous condensate from the distillation unit is passed over a bed of a cation exchange resin in its protonated from to provide a purified condensate, and the purified condensate is used as extractant for extracting hydrogen peroxide in the anthraquinone process, as column reflux for the distillation unit or as a diluent for diluting an aqueous hydrogen peroxide solution.
    Type: Grant
