Redesign, Optimization, and Economic Evaluation of a Natural Gas Combined Cycle with the Best Integrated Technology CO2 Capture

Natural gas combined cycle power plants with CO2 capture – Opportunities to reduce cost

“…The economic analyses published in the recent past have mostly covered the basic MEA process and have principally considered the removal of CO 2 from coal-derived flue gases (Abu-Zahra et al, 2007b;Desideri and Paolucci, 1999;Rao and Rubin, 2002;Romeo et al, 2008;Singh et al, 2003). The economical viability of NGCC power plants with chemical absorption capture of CO 2 has been more moderately studied, and the simple absorption/stripping process has also been examined (Botero et al, 2009;Chiesa and Consonni, 2000;Finkenrath et al, 2007). A comprehensive analysis of the technical performance and costs of post-combustion CO 2 absorption from a NGCC power plant has been presented by Peeters et al (2007).…”

Performance of a triple power generation cycle combining gas/steam turbine combined cycle and solid oxide fuel cell and the influence of carbon capture

“…System-level studies include configuring the capture unit and finding optimal integration between the capture unit and the power cycle Papers have been published on the topics of reduction of the efficiency penalty by modifying the carbon capture method [19,20], system optimization and economic evaluation [21,22] and improvement of carbon capture process focusing on regenerator and reboiler [23,24]. A good summary of recent works on the application of postcombustion capture to GTCCs and a comparison of predicted performance penalties reported in different studies can be found in a recent study [25].…”

Performance evaluation of an Organic Rankine Cycle fed by waste heat recovered from CO2 capture section

“…With respect to compressing ambient air, a higher temperature of the air-flue gas mixture entering the compressor and a higher heat capacity of the recirculated gas, which is more humid, are obtained [27]. On the contrary, in an NGCC with CO2 post-combustion capture, EGR has been proposed earlier in order to improve the capture efficiency and substantially reduce capture equipment costs [22,27]. In fact EGR leads to a higher CO2 concentration in the flue gas and a reduced size of the CO2 capture unit.…”
