| Abstract: | A hydrophobic microporous hollow-fibre membrane module was used to determine the overall mass transfer coefficient ( K G ) in the CO 2-NaOH solvent vapor absorption system under various operation conditions A model for overall mass transfer coefficient calculation was developed and the model agreed well with experiments Based on the model and experiments, the behaviour of solvent vapor absorption process was examined and some measures for increasing overal l mass transfer coefficient were proposed |
