摘要The effects of recycle on membrane extraction through a cross-flowrectangular module have been studied both theoretically andexperimentally. Theoretical analysis of mass transfer in cross-flowdevice with and without recycle was analogous to heat transfer incross-flow heat exchangers. Experiments were carried out with the useof a membrane sheet made of microporous polypropylene as a permeablebarrier to extract acetic acid from aqueous solution by methylisobutyl ketone. Theoretical predictions are in agreement with theexperimental results. Contrast a device without recycle, improvementin mass transfer is achievable if cross-flow membrane extraction isoperated in a device of same size with recycle which provides theincrease of fluid velocity, resulting in reduction of mass-transferresistance.
