TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Components: The system further comprises a carbon dioxide separation system to separate the carbon dioxide from the nitrogen within the gas mixture, and a cooler for cooling the gas mixture before injection of the carbon dioxide and the nitrogen from the gas mixture into the methane hydrates. The low emissions power plant comprises an expander turbine to provide mechanical energy by extracting energy from the gas mixture after combustion of the gas mixture in a combustor, a generator to generate electricity from the mechanical energy provided by the expander turbine, and a combined cycle power plant. The combined cycle power plant comprises an expander turbine to provide mechanical energy by extracting energy from the gas mixture after combustion of the gas mixture in a combustor, a heat recovery steam generator (HRSG) to generate steam by heating a boiler with an exhaust stream from the expander turbine, a steam turbine to provide mechanical energy by extracting energy from the steam generated by the HRSG, and a generator to generate electricity from the mechanical energy provided by the expander turbine and the steam turbine. Preferred Process: The methane recovery system recovers the methane from the methane hydrates by separately injecting the carbon dioxide and the nitrogen into the methane hydrates without separating the nitrogen from the carbon dioxide within the gas mixture. The ratio of the nitrogen to the carbon dioxide within the gas mixture is adjusted before injection of the gas mixture into the methane hydrates. At least a portion of the methane recovered from the methane hydrates is flowed into the combustor as fuel. A portion of the gas mixture is recycled to the low emissions power plant. The low emissions power plant is configured to operate at a balanced condition. The methane is recovered from the methane hydrates by increasing temperature of the methane hydrates by contacting the methane hydrates with the nitrogen, and dissociating the methane from the methane hydrates by contacting the methane hydrates with the carbon dioxide. The method further involves removing impurities from the methane recovered from the methane hydrates. The expander turbine is configured to operate at a balanced condition, where at least a portion of the gas mixture is recirculated to the combustor.
