CO2 Capture from Natural Gas Combined Cycles

This paper presents a comprehensive analysis of three near-term plant configurations for CO2 capture from natural gas-fired power plants based on combined cycle: (i) amine post-combustion separation, (ii) syngas decarbonization, (iii) oxy-combustion. We address them as ‘near-term’ because they do not involve the development of components requiring unproven technology. All configurations are based on a common set of assumptions, reproducing the performance of a status-of-the-art combined cycle based on ‘FB technology’ gas turbine. The performance prediction shows that the best efficiency is achieved by post-combustion (with a loss of efficiency of 6.4 points), followed by pre-combustion, both showing about 90% carbon capture. Oxy-combustion shows a lower efficiency with lower emissions (98% capture, virtually no CO, UHC and NOX emissions). The post-combustion solution also shows the best economics
