  • Patent number: 11208364
    Abstract: The present disclosure provides oxidative coupling of methane (OCM) systems for small scale and world scale production of olefins. An OCM system may comprise an OCM subsystem that generates a product stream comprising C2+ compounds and non-C2+ impurities from methane and an oxidizing agent. At least one separations subsystem downstream of, and fluidically coupled to, the OCM subsystem can be used to separate the non-C2+ impurities from the C2+ compounds. A methanation subsystem downstream and fluidically coupled to the OCM subsystem can be used to react H2 with CO and/or CO2 in the non-C2+ impurities to generate methane, which can be recycled to the OCM subsystem. The OCM system can be integrated in a non-OCM system, such as a natural gas liquids system or an existing ethylene cracker.

  • Publication number: 20180215682
    Abstract: The present disclosure provides methods for producing hydrocarbon compounds, which may comprise directing a feed stream comprising methane (CH4) and an oxidizing agent into an oxidative coupling of methane (OCM) unit to generate from at least a portion of the CH4 and the oxidizing agent an OCM effluent comprising the hydrocarbon compounds. A portion of the OCM effluent may be directed into a recycle loop that comprises (i) a hydrogenation unit that hydrogenates at least a portion of unsaturated hydrocarbons from the additional portion of the OCM effluent, and (ii) a methanation unit that reacts hydrogen with carbon monoxide or carbon dioxide from the additional portion of the OCM effluent in a methanation reaction to form CH4. The recycle loop may output a recycle stream comprising the CH4 generated by the methanation unit. At least a portion of the recycle stream may be directed into the OCM unit.
