    Abstract: Processes and apparatuses for recovering a high purity carbon dioxide stream. A first separation zone that may include a cryogenic fractionation column provides the high-purity CO2 stream. A vapor stream from the cryogenic fractionation column is passed to a second separation zone to separate the CO2 from the other components. The second separation zone may include a pressure swing adsorption unit or a solvent separation unit. The second separation zone provides a hydrogen enriched gas stream that may be used in a gas turbine. The second stream from the second separation zone includes carbon dioxide and, after a pressure increase in a compressor, may be recycled to the first separation zone.

    Abstract: Methods and apparatuses for removing impurities from a hydrocarbon stream are provided herein. In an embodiment, a method for removing impurities from a hydrocarbon stream includes providing the hydrocarbon stream that includes carbon dioxide in an amount of greater than about 50 ppm by mole. Carbon dioxide is selectively adsorbed from the hydrocarbon stream to produce a treated hydrocarbon stream that has less than or equal to 50 ppm by mole of carbon dioxide. The adsorbed carbon dioxide is desorbed to produce a raffinate stream that includes the carbon dioxide. The carbon dioxide is separated from the raffinate stream using a solvent separation technique to produce a treated raffinate stream.

    Abstract: A method for conditioning natural gas into a fuel gas suitable for use as fuel to an engine includes delivering a natural gas stream to a membrane separator. The natural gas stream has a heating value greater than or equal to about 1.15×106 Joules (about 1100 BTU). The method further includes separating the natural gas stream in the membrane separator into a residue stream and a permeate stream. The residue stream includes C2+ hydrocarbons at a concentration greater than a concentration of C2+ hydrocarbons in the natural gas stream, and the permeate stream includes methane at a concentration greater than a concentration of methane in the natural gas stream. Still further, the method includes delivering the permeate stream to an engine for use as fuel gas to the engine.

    Abstract: Systems and methods for gas separation are disclosed. In one exemplary embodiment, a method for gas separation includes the steps of contacting a feed gas stream that includes a product gas and an impurity gas with a liquid-phase absorption solvent and absorbing the impurity gas and a portion of the product gas of the feed gas stream into the liquid-phase absorption solvent. The exemplary method further includes the steps of subjecting the liquid-phase absorption solvent to a first reduced pressure environment to remove the portion of the product gas and a portion of the impurity gas from the liquid-phase absorption solvent and separating the portion of the product gas from the portion of the impurity gas.
