“…Table 2 presents the results for the full load operation of the micro gas turbine in dry and wet mode, the latter being at the maximum steam/air ratio. The data are in accordance to the results presented in the literature [9,15] and small deviations can be attributed to the applied compressor map and the used fuel composition.…”

“…This fact motivated the theoretical and experimental investigations of Delattin et al [15] and De Paepe et al [16] on steam injection in the Turbec T-100. They have shown that the existence of the recuperator limits the technically feasible rate of steam injection.…”

“…ASPEN PLUS is used to model the operation of the Turbec T-100 [15], which is assumed to be a representative recuperated micro gas turbine, for the size of plants in question. In a first step, the commercial machine is modeled in order to validate the code with data from existing literature.…”

“…Their experiments have also proven that compressor surge is not expected to be a problem for the range of steam injection rates feasible in micro gas turbines. Although the work of Delattin et al [15] included an economic evaluation of wet mGT operation, this was not its focus and the results are not necessarily reliable.…”

“…The model results with characteristic maps are in good agreement with the manufacturer's reference data (Turbec, 2000) as indicated in Table 3, and the already published results of the model developed for the MGT through different process modelling tools (Ali et al, 2014;Ali et al, 2015b;De Paepe et al, 2012;Delattin et al, 2008;Kautz and Hansen, 2007;Majoumerd et al, 2014;Nikpey et al, 2014;Nikpey Somehsaraei et al, 2014;Parente et al, 2003). The comparison of the present model results with the previously published model results are presented in Table A.…”

AbstractGas turbines are a viable and secure option both economically and environmentally for combined heat and power generation. Process modelling of a micro gas turbine for CO 2 injection and exhaust gas recirculation (EGR) is performed. Further, this study is extended to assess the effect of the CO 2 injection on the pilot-scale CO 2 capture plant integrated with a micro gas turbine. In addition, the impact of the EGR on the thermodynamic properties of the fluid at different locations of the micro gas turbine is also evaluated. The micro gas turbine and CO 2 injection models are validated against the set of experimental data and the performance analysis of the EGR cycle results in CO 2 enhancement to 5.04 mol% and 3.5 mol%, respectively. The increased CO 2 concentration in the flue gas, results in the specific reboiler duty decrease by 20.5 % for pilot-scale CO 2 capture plant at 90 % CO 2 capture rate for 30 wt. % MEA aqueous solution. The process system analysis for the validated models results in a much better comprehension of the impact of the CO 2 enhancement on the process behaviour.Keywords: Micro gas turbine; Process modelling; CO 2 injection; Exhaust gas recirculation; Specific reboiler duty. Nomenclature IntroductionThe energy trend across the globe is changing due to the overwhelming concern regarding emission of greenhouse gases from the power generation sector (IEA, 2012). The contribution of the conventional power generation system, including coal-and natural gas-power generation, is in the gradual transition stage towards more sustainable systems, as towards low or zero carbon emission emitters. However, natural gas-fired power plants are a secure and viable option both economically and e...
