  • Regeneration of acid containing peroxy acids of sulfur
    Patent number: 11584644
    Abstract: A method for treating a spent oxidizing acid which contains at least one of H2O2 and one or more peroxy acids of sulfur comprising contacting the spent oxidizing acid with a quantity of SO2 in excess of an equilibrium quantity required to convert the H2O2 and peroxy acids of sulfur to sulfuric acid.
    Type: Grant
    Filed: February 15, 2022
    Date of Patent: February 21, 2023

  • Regeneration of acid containing peroxy acids of sulfur
    Patent number: 11345594
    Abstract: A method of treating a spent oxidizing acid is provided comprising the steps of contacting a spent acid containing peroxy acids of sulfur with a quantity of SO2 in excess of an equilibrium quantity required to convert the peroxy acids to sulfuric acid. The excess SO2 is catalytically converted to SO3, and the SO3 is absorbed into the sulfuric acid stream essentially free of H2SO5 and H2O2 to make product sulfuric acid.
