Investigation of membrane wetting in different absorbents at elevated temperature for carbon dioxide capture

In order to investigate the mechanism of membrane wetting in the membrane absorption process at elevated temperature, the commercial polypropylene (PP) hollow fiber membrane was used to simulate the absorption exposure conditions by immersing the membrane into different absorbents at 60 'C up to 40 days. Three absorbents which are 30 wt% of aqueous monoethanolamine (MEA), 2-amino-2-hydroxymethyl-1,3-propanediol (TRAM) and potassium sarcosinate (I
