“…The commercial chemical process simulator, Pro/II Ò V8.1.1, is used in the study to build the analysis model. A series of process simulation models have been established during the past years, for example, Chen et al (2012a) has reported a process analysis study of IGCC with CO 2 capture. To analyze the system performance of IGCC with CO 2 capture.…”

“…Table 9 illustrates the compositions of natural gas and syngas utilized in the study. The former is cited from the NETL report, while the latter represents typical values of syngas downstream WGS reactor, for CO 2 capture, as reported by Chen et al (2012a). For the case of mixture gas with SNG and syngas, the maximum ratio of syngas to SNG is 0.14, due to the constraint for keeping the composition of methane at a value of 80 mol %, to meet the minimum requirement of NG in Taiwan.…”

In the 21st century, fossil fuels will remain the mainstay of energy production, while natural gas combined cycle (NGCC) features environmental benignity and high efficiency. Hence, it is desirable to assess the potential of NGCC for power generation, in which gas turbine (GT) is operated with alternative gaseous fuel from coal gasification, since coal is the most abundant fossil fuel. Systemlevel analyses for NGCC plants, combining advanced GTs with various fuels, are performed in this study. The commercial chemical process simulator, Pro/II Ò V8.1.1, is implemented to build the simulation models. This work further performs various analyses as the basic and feasibility cases. The former is the benchmark case verified with the reference data of an operating NGCC power plant located in northern Taiwan. The latter introduces a feasibility study with advanced GTs and actual parameters in Taiwan. Alternative fuel, including synthetic natural gas (SNG) or a mixture of SNG and syngas, is fed to combined cycle for evaluating the overall performance. The results indicate that the system output or efficiency in either case is slightly (2-3 % points, LHV) lower than the counterpart in the benchmark one. In Taiwan, the natural gas price is much higher than that of coal, and results in higher idle capacity of NGCC. The advantage of adopting SNG to NGCC is that it could increase the capacity factor and subdue the environmental impact of the energy portfolio. The outcome of this study indicates a possible means to utilize coal more efficiently and reduce emissions.

“…Those adjustments were needed to maintain the gas turbine power output on target. The efficiency penalties for 50% and 90% CO 2 capture were 3.26 and 5.48 percentage points, respectively [99]. Gazzani et al investigated an innovative pre-combustion based system for CO 2 capture called Sorption-Enhanced Water Gas Shift (SEWGS) that integrates water-gas-shift and CO 2 separation steps [100].…”
