ABSTRACT:
The overall mass transport efficiency of hollow fiber membrane separation cells is increased by introducing segmented flow into the bores of the fibers. The invention is preferably practiced by dispersing a gas segmentation phase into a continuous liquid phase and feeding the dispersion into the bores of the fibers to form alternating flowing segments of gas and liquid.
