“…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...

“…In order to make up for the evaporated water, feedwater is added to the system. More details regarding the mass and energy balances and the temperatures and pressures in each component of the cycle (for the mGT Turbec T100 and the mHAT) can be found on [18,8,19]. De Paepe et al conducted thermodynamic simulations of the VUB T100 mHAT cycle in Aspen Plus confirming that the electrical efficiency increases, with water injection, by 2% or 3.8% depending on whether the controller is set to keep the Turbine Outlet Temperature (TOT) or TIT constant [8].…”
