| 摘要 |
A process is described for reducing the CO2 emissions from a combined cycle power generation process utilizing a gaseous hydrocarbon feed, comprising splitting the hydrocarbon feed into two portions; a first smaller portion comprising =45% by volume of the feed and a second larger portion comprising =55% by volume of the feed, feeding the first smaller portion to an autothermal reforming process to generate a hydrogen-containing gas and a carbon dioxide stream, combining the hydrogen-containing stream with the second portion of the gaseous hydrocarbon, combusting the resulting hydrogen-containing fuel stream with an oxygen containing gas in a gas turbine to generate electrical power and passing the exhaust gas mixture from the gas turbine to a heat recovery steam generation system that feeds one or more steam turbines to generate additional electrical power. The captured carbon dioxide stream may be fed to storage or enhanced oil recovery processes. The process may be usefully retrofitted into existing combined cycle processes. |
