In this study, membrane vacuum stripping process was applied to desorption process for the purpose of the reduction of desorption energy in an amine absorption process. 30 wt% of aqueous MEA (monoethanolamine), DEA (diethanolamine), TEA (triethanolamine) solution were used as the absorbent and PE (polyethylene) was used as a support of composite membrane. PDMS (polydimethylsiloxane) knowing flaxable and high permeability was coated on the one side of PE support with desired thickness. The stripped CO2 fluxes were checked at various solution temperatures and vacuum pressures.
