  • Patent number: 5945391
    Abstract: A vehicle and method for storing ozone is disclosed. A vehicle made of a water miscible, organic compound of a glycol-containing chemical compound, a tertiary alcohol or a mixture thereof that is capable of receiving and containing ozone is disclosed. The method involves producing ozone gas, introducing the ozone-containing gas into a mixing vessel that contains the aforementioned organic compound, agitating the organic compound in the presence of the ozone-containing gas, wherein the ozone-containing gas is at atmospheric pressure or at a pressure of up to about 150 psig., and releasing the pressure if pressures in excess of atmospheric are used.
    Type: Grant
    Filed: October 20, 1997
    Date of Patent: August 31, 1999
    Assignee: Quantum Technologies, Inc.
    Inventors: Robert E. Yant, Marilyn M. Hurst, David B. Galluch

  • Patent number: 4740212
    Abstract: A process and composition especially suited for bleaching wood pulp characterized by the use of hypochlorous acid in combination with chlorine dioxide and/or a nitrogen compound having the characteristic of minimizing fiber degradation and enhancing fiber brightness. The preferred composition is in an aqueous solution adjusted to an optimum pH and is used as a direct replacement for conventional compositions so as to effect substantial savings in the costs of chemicals and energy per ton of bleached pulp.

  • Patent number: 4693832
    Abstract: A disinfection process is provided for preparing potable water having an unusually persistent and long lasting free available chlorine residual in order to assure safety and integrity of said water during its passage through the distribution system by which it is delivered to the consumer. The key step of this process is the generation of said unusually persistent free chlorine residual by mixing into a semi-finished water, which has already been pretreated specifically to satisfy substantially its immediate chlorine demand, dilute solution of HOCl having a pH between about 3 and about 6.
