Abstract

Several technologies have been developed for capturing carbon dioxide (CO₂), but absorption remains the most suitable method for large-scale industrial operations. In recent years the use of gas absorption membrane (GAM) systems has been explored as an alternative to traditional packed columns. This paper evaluates the performance of a GAM system and a packed column using the overall mass transfer coefficient (K_Gav) as a basis for comparison. The GAM system tested microporous polypropylene (PP) and poly(tetrafluoroethylene) (PTFE) hollow fiber membranes while the packed column contained Sulzer DX structured packing. Aqueous solutions of monoethanolamine (MEA) and 2-amino-2-methyl-1-propanol (AMP) were used in both absorbers. Experimental results showed that the GAM system performed better than the packed column. GAM systems deserve the attention they have been receiving from researchers as they have significant potential to replace packed columns.
