In this work, 4-diethylamino-2-butanol (DEAB) as a new type of alkanolamine solvent is used for CO 2 capture in hollow fiber membrane contactor (HFMC). A model describing the gas and liquid reactions transport inside under wetting or non-wetting conditions was built. The countercurrent flow natural considered model. To investigate influence on decarburization efficiency, DEAB compared with othe...
