  • Publication number: 20190159471
    Abstract: A method of treating a product or surface with a reactive gas, comprises producing the reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas; transporting the reactive gas at least 5 cm away from the HVCP; followed by contacting the product or surface with the reactive gas. The HVCP does not contact the product or surface.

  • Patent number: 9321663
    Abstract: Oily and/or solids-containing water is clarified by chemical treatment to form flocculated and agglomerated solid phases and a clear water phase. In the clarification process, microbubbles of air or other gas are introduced at atmospheric pressure, via an eductor or other suitable device, together with a flocculant. During the subsequent formation of floes and their agglomeration into larger masses, microbubbles become entrained within and adhered to the solid flocculated materials. The resulting masses are very buoyant and easily separated from the water via a variety of approaches that include skimming, decanting, filtration, and screening. This process results in a solids phase that may be disposed of as waste, if desired, and a highly clarified water phase.

  • Patent number: 8410194
    Abstract: The biopolymer additive, in combination with water, functions as a soil conditioner that affects soil erosion and water infiltration. The biopolymer additive is derived from complex galactomannon-rich succulent plants. The succulent-derived (biopolymer) additive (SDA) may be used alone or in combination with polymers and copolymers of polyacrylamide (PAM). The combination of the SDA and PAM has a synergistic effect so that the resulting composition yields unexpected results and is a more effective treatment than either SDA or the PAM alone.

  • Publication number: 20040213755
    Abstract: Novel compositions and methods for reducing odor. The composition comprises at least one synthetic zeolite, at least one acid and at least one substance selected from a metal oxide, metal, or salt of a metal or metal oxide. A wide range of odors, including ammonia and sulfurous odors, may be controlled by contacting an effective amount of the above composition with the article, substance or environment that emits the undesired odor. The composition may also be incorporated into other substances for odor reduction or control to form odor-controlled articles.

  • Patent number: 5310529
    Abstract: There is disclosed an improved process for the preparation of phosphorus trichloride wherein elemental phosphorus is caused to react with chlorine. The improvement comprises continuous, high speed analysis of the contents of the reactor whereby the reaction is controlled to produce less phosphorus pentachloride and other by-products. The analysis is performed by a laser Raman spectrometer associated with an optrode having a remotely located probe head and a circulating sampling system to continuously provide fresh sample to the probe head continuously. Also disclosed is apparatus for the automatic control of the reaction by control of the reactant feed to the reactor in response to the on-line, continuous analysis of the reactor contents.
