METHOD AND APPARATUS TO FACILITATE SUBSTITUTE NATURAL GAS PRODUCTION

摘要

A method of producing substitute natural gas (SNG) includes providing a syngas stream that includes at least some carbon dioxide (CO2) and hydrogen sulfide (H2S). The method also includes separating at least a portion of the CO2 and at least a portion of the H2S from at least a portion of the syngas stream provided. The method further includes channeling at least a portion of the CO2 and at least a portion of the H2S separated from at least a portion of the syngas stream to at least one of a sequestration system and a gasification reactor.
