  • Patent number: 9750258
    Abstract: A stabilized composition is disclosed which contains at least two biocides, particularly at least two non-oxidizing biocides. In one embodiment, the composition contains a phosphonium sulfate compound combined with a dialkyl dimethyl quaternary amine compound. In order to stabilize the composition, an alkyl trimethyl ammonium compound is added to the composition. In one embodiment, the stabilizing agent produces a single phase composition. With the aid of the stabilizing agent, the single phase concentrated compositions can be produced that can later be diluted for use. In one embodiment, the composition may be used to treat aqueous systems in industrial applications.

  • Patent number: 9752083
    Abstract: A method of reducing the amount of sulfhydryl compounds from sour hydrocarbon fluids is described. In the method, an aldehyde-releasing compound, which is high temperature stable and is highly water-soluble, is introduced to a hydrocarbon fluid stream as a scavenger for sulfhydryl compounds. The aldehyde-releasing compound is allowed to mix with the hydrocarbon fluid stream and the aldehyde-releasing compound is allowed to react with the sulfhydryl compounds present in the hydrocarbon fluid stream, thereby reducing the presence sulfhydryl compound in the hydrocarbon fluid stream.

  • Patent number: 9687432
    Abstract: Antimicrobial bispyridine amine compositions that facilitate easy application on the skin, do not penetrate the skin, are compatible with typical deodorant ingredients, and do not cause adverse effects on skin and clothing. In one aspect, the present invention relates to an antimicrobial composition including an organic acid salt of a bispyridine amine where the organic acid contains from about 4 to about 30 carbon atoms. Because the organic acid salts of bispyridine amines are large molecules, they will not easily penetrate the skin, and will stay on the surface where they were applied and where they are needed to have their effect.

  • Patent number: 9334182
    Abstract: The invention relates to a method for the prevention and removal of H2S and/or other sulfhydryl compounds and iron sulfide deposits from gas and/or liquid streams in industrial process systems. Formulations comprising aldehydes, aldehyde donors, and/or aldehyde stabilizers, excluding triazines, in combination with the reaction product of an amino acid and a hydroxymethylphosphine or hydroxymethylphos-phonium salt, and optionally a quaternary ammonium compound and/or one or more N-hydrogen compounds such as 5,5-dialkylhydantoin or amines, are rapidly and sustainedly scavenging H2S originating from process and/or microbial sources.

  • Patent number: 9220272
    Abstract: Disclosed is an antimicrobial composition containing an active halogen-containing component having a source of an active halogen and having an elevated pH, which is mixed with an acidic component. An acidic component is added in an amount to the active halogen-containing component to reduce the pH of the antimicrobial composition. When the pH of the active halogen-containing composition is reduced, the resulting composition has been discovered to be effective as a disinfectant and, particularly, as a sporicide. Application methods for applying the composition are also described.

  • Patent number: 8933244
    Abstract: Disclosed are compositions for stabilizing a source of active halogen in aqueous solution. The compositions comprise (i) at least one substituted N-hydrogen compound, such as 5,5-dimethylhydantoin, and (ii) at least one additional nitrogen compound selected from ammonia, ammonium salts, and nitrogen compounds containing no carbon-hydrogen bonds, the molar ratio of (i) and (ii) being in the range of 50:1 to 0.02:1. Active halogen-containing aqueous solutions stabilized by the above compositions are particularly useful for controlling microbial and planktonic growth in aqueous systems such as process liquids in the pulping or papermaking industry. The compositions are also useful in reducing the corrosivity of halogen-containing solutions.
