Conventional methods for improving the hydrophobicity of polypropylene (PP) membranes to prevent wetting phenomena require complex pretreatment procedures in order activate surface enabling reaction with fluorosilane (FS)-based materials. This study successfully prepared PP membrane contactors enhanced through a simple single-step dip-coating method using perfluoroether-grafted silanes CO2 capt...

In the current study, a rigorous modeling approach was used to develop mathematical model for non-isothermal absorption process of CO2 in hollow fiber membrane contactors (HFMC). Four amino acid-based ionic liquids (ILs) namely, tetramethylammonium glycinate [N1111][Gly], 1-ethyl-3-methylimidazolium [C2mim][Gly], 1-butyl-3-methylimidazolium [C4mim][Gly] and 1-hexyl-3-methylimidazolium [C?mim][G...

In this work, carbon dioxide (CO2) loading capacity of methyldiethanolamine (MDEA) solution promoted by potassium lysinate (KLys) was experimentally measured using a gas absorption setup at different concentrations and temperatures. The CO2 removal efficiency the MDEA + KLys investigated for CO2/N2 mixture computational fluid dynamic (CFD) simulations in hollow fiber membrane contactor (HFMC). ...

Effect of fractional gas hold-up εG on volumetric mass transfer coefficient KLa were studied for two different type of airlift contactors conventional and modified. KLa was directly proportional to gas hold-up within bubbly flow regime (UG < 0.075 m/s ) in conventional one but reverse trend ( inversely proportional) was reported in modified airlift contactor. Mathematical relation between KLa a...
