  • Patent number: 8664462
    Abstract: A method of processing feed streams high in hydrogen sulfide is provided. The method includes providing a feed gas stream that includes hydrocarbons and at least 5 vol % hydrogen sulfide. At least a portion of the feed gas stream is separated into a hydrogen sulfide stream and a hydrocarbon stream. The hydrocarbon gas stream is processed to produce natural gas. At least 34 mol. % of the hydrogen sulfide in the hydrogen sulfide stream is combusted with an oxidant to generate thermal power. Thermal power generated by the combustion is utilized in one or more of the steps of separating the feed gas stream into the hydrogen sulfide stream and the hydrocarbon gas stream, and processing the hydrocarbon gas stream to produce natural gas, compressed natural gas, or liquefied natural gas.
