Abstracts

EN

The process of carbon dioxide removal from monoethanolamine (MEA) - water solution was investigated on Poly Di Methyl Siloxane (PDMS) hydrophobic tubular membrane with a ceramic support. The effects of feed temperature, liquid flow rate and MEA concentration on CO2 mass transfer and selectivity were examined and found to be with a reasonable deviation (±25%) with predictions based on the multilayer film model. The membrane resistance was evaluated in separate experiments. The measured CO2 mass fluxes (0.17-0.45 kg/(m2h)) were found to be independent of the MEA concentration in the feed.
