  • Patent number: 10589213
    Abstract: Embodiments include systems and methods for processing a feed gas and acid gas removal. A method may comprise receiving a feed gas to an absorber; contacting the feed gas counter-currently with a lean solvent stream to remove acid gas from the feed gas; producing a treated feed gas stream from the absorber; producing a rich solvent stream from the absorber comprising H2S and CO2 removed from the feed gas; receiving a side stream from the absorber to a side cooler; removing at least a portion of the heat of absorption from the side stream by the side cooler; producing a first output stream from the side cooler that is routed back into the absorber at a point below a draw point for the side stream; and producing a second output stream from the side cooler that is routed back into the absorber at a point below the first output stream.

  • Patent number: 10590358
    Abstract: A system for processing a gas stream can include an acid gas removal unit comprising a first absorber unit, a compressor, and a second absorber unit. The first absorber unit is configured to receive a feed gas stream containing organic sulfur species and acid gas components, remove at least a portion of the organic sulfur species and acid gas components using a semi-rich solvent at a first pressure, produce a semi-treated gas stream, and produce a rich solvent stream. The compressor unit is configured to compress the semi-treated gas stream from the first pressure to a higher second pressure. The second absorber unit is configured to receive the compressed semi-treated gas stream, remove at least a portion of any organic sulfur species and acid gas components present in the compressed semi-treated gas stream using a lean solvent, produce the semi-rich solvent stream, and produce a treated gas stream.

  • Patent number: 10358614
    Abstract: Embodiments relate generally to methods and systems for processing a gas stream and for removing mercaptans from a feed stream. A method may comprise compressing a semi-treated gas stream, wherein the semi-treated gas stream comprises organic sulfur species and acid gas components; contacting the semi-treated gas stream with a lean solvent; removing at least a portion of the organic sulfur species and acid gas components from the semi-treated gas stream to produce a treated gas stream and a semi-rich solvent stream; contacting a feed gas stream with the semi-rich solvent, wherein the feed gas stream comprises organic sulfur species and acid gas components; and removing at least a portion of the organic sulfur species and acid gas components from the feed gas stream to produce the semi-treated gas stream based on contacting the semi-rich solvent with the feed gas stream.

  • Patent number: 8653157
    Abstract: A polyurethane compound is disclosed, comprising the reaction product of an isocyanate and one or more polyols including at least one polytetramethylene ether glycol and polyethylene wax. The latter two ingredients greatly enhance abrasion resistance of the compound, making the compound particularly suitable for use as an outsole of footwear for rugged use applications.

  • Publication number: 20070062216
    Abstract: Liquefied natural gas (LNG) is heated in a plant by a heat source and the heated LNG is expanded to produce work. In particularly preferred plants, the heat source is a combined cycle power plant, and the work is used to recompress pipeline gas produced from the heated LNG. Additionally, the refrigeration content in LNG may be utilized to increase the power generation capacity and efficiency of a combined cycle power plant.
