摘要:This study investigated the prospect of using aqueous mixture of 1-butylpyridinium tetrafluoroborate ([Bpy][BF4]) ionic liquid (IL) and monoethanolamine (MEA) as solvent in post-combustion CO2 capture (PCC) process.This is done by analysis of the process through modelling and simulation.In literature,reported PCC models with a mixture of IL and MEA solvent were developed using equilibrium-based mass transfer approach.In contrast,the model in this study is developed using rate-based mass transfer approach in Aspen Plus(R).From the results,the mixed aqueous solvent with 5-30 wt% IL and 30 wt% MEA showed 7%-9% and 12%-27% less specific regeneration energy and solvent circulation rate respectively compared to commonly used 30 wt% MEA solvent.It is concluded that the IL concentration (wt%) in the solvent blend have significant impact on specific regeneration energy and solvent circulation rate.This study is a starting point for further research on technical and economic analysis of PCC process with aqueous blend of IL and MEA as solvent.
