20080264250 | Flue Gas Desulfurization Process Utilizing Hydrogen Peroxide - A flue gas desulfurization process in which a SO | 10-30-2008 |
20090043123 | Dilute Stabilized Peracetic Acid Production and Treatment Process - A process for the rapid production and stabilization of dilute aqueous peracetic acid in which acetic anhydride and hydrogen peroxide are reacted in an aqueous medium with a stoichiometric excess of hydrogen peroxide and the aqueous medium containing the peracetic acid reaction product is adjusted, as necessary, to a pH of less than about 8 to provide a stabilized dilute peracetic acid solution. The dilute peracetic acid may be produced on site or in situ for treatment of an aqueous medium requiring disinfecting, biocidal, antimicrobial or bleaching treatment. | 02-12-2009 |
20100160449 | Peracetic Acid Oil-Field Biocide and Method - Aqueous well treatment fluid compositions with biocidal activity are disclosed comprising a polymer for modifying fluid viscosity in the aqueous fluid, an organic monocarboxylic peracid being present in an anti-microbial amount of about 1 ppm to about 1000 ppm, and a controlled amount of hydrogen peroxide also being present. Peracetic acid is the preferred peracid. The viscosity-modifying polymer in the aqueous well treatment fluid composition may serve to reduce friction in the fluid or increase fluid viscosity. A method of using such compositions is also disclosed. | 06-24-2010 |
20100222242 | PERACID OIL-FIELD VISCOSITY BREAKER AND METHOD - Aqueous well treatment fluid compositions are disclosed comprising an aqueous fluid containing polymer or copolymer for modifying fluid viscosity of the aqueous fluid and, in addition, an agent for effecting a controlled reduction in the aqueous fluid viscosity in a subterranean environment. The viscosity-reducing agent comprises a dilute concentration of peracetic acid. A method of using such compositions in oil- and gas-field treatment operations is also disclosed. | 09-02-2010 |
