  • Patent number: 8858680
    Abstract: The present invention is directed to a method and a system for separating oxygen from air. A compressible air stream that contains oxygen is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which oxygen is capable of being preferentially absorbed. Rotational velocity is imparted to the mixed streams, separating an incompressible fluid in which at least a portion of the oxygen is absorbed from other compressible components of the air stream. The compressible air stream may be provided at a stream velocity having a Mach number of at least 0.1.

  • Patent number: 8858784
    Abstract: A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a catalyst to produce a vapor comprising a first hydrocarbon-containing product. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal to produce a second hydrocarbon-containing product.

  • Patent number: 8138381
    Abstract: The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises greater than 40 vol. % of the extracted gas. The extracted gas is scrubbed with a wash effective to produce a washed extracted gas containing less carbon dioxide than the extracted gas and at least 20 vol. % carbon dioxide. The washed extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid methanol product.
