Low-temperature vacuum stripping of CO2 from aqueous amine solutions using thin-film silicalite-filled PDMS composite membranes |
| 초록 |
Carbon dioxide (CO2) recovery by vacuum stripping technology using membranes was studied in conventional aqueousamine absorption process. Composite membranes were prepared by coating hydrophobic silicalite-filled polydimethylsiloxane (PDMS) layers on polyethylene (PE) porous supports and used as new membrane strippers for CO2 recovery to prevent the typical pore wetting problem. Aqueous 30 wt% solutions of monoethanolamine (MEA), diethanolamine (DEA). CO2 stripping fluxes increased with increasing temperature and CO2 loading of amine solutions as well as with decreasing stripping pressures because of the enhanced upstream and downstream driving forces. CO2 stripping fluxes were much higher in the TEA and DEA solutions than in the MEA solutions. The thin film silicalite-filled PDMS composite membranes showed long-term stability. |
