Abstract
Aspen Plus v8.8 was used to perform techno-economic analysis (TEA) of a CO2 capture process from a typical fuel gas stream in a 543-MW pre-combustion power plant using five different physical solvents (Selexol, PEGPDMS-1, NMP, [aPy][Tf2N] and [hmim][Tf2N]). The process included a countercurrent packed-bed absorber operating under high-pressure over a wide range of temperatures and three pressure-swing flash drums for solvent regeneration. Two packings, Mellapak 250Y and IMTP50, were used and the Levelized costs of CO2 captured (LCOC) were calculated. The simulation results indicated that using Mellapak 250Y exhibited lower LCOC values than those when using IMTP50 for the five solvents under ..
