Popis:	In the present work, steady-state simulations of the natural gas combined cycle (NGCC) and the post-combustion CO2 capture (PCC) processes have been modelled in Aspen Plus® environment. The capture plan model was validated with data from the Colombian power plant "Termocentro" at 300MWe. A techno-economical evaluation study has been performed for both a combined cycle (gas and steam) and the PCC process. The PCC process was based on the solvent 30% (w/w) MEA-H2O and on the solvent H2O-30% (w/w)-MEA-5% (w/w))-[Bmim][Bf4]. Sensitivity analysis was carried out, giving as a result an optimum concentration of 5% (w/w) for the 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid ([Bmim] [BF4]) solvent. The study indicates how with efficient operation conditions of solvent regeneration, [Bmim][Bf4] may be used for CO2 capture plans on the future.
