Experimental Study of Mass Transfer in Membrane Absorption Process Using Membranes with Different Porosities
TL;DR: In this paper, the effect of membrane porosity on mass transfer depends on both the absorbent pH value and liquid velocity, and it is shown that the mass transfer coefficients based on the whole membrane area remain almost the same at different membrane porosities.

Designing hollow-fiber contactors
Ming-Chien Yang,Edward L Cussler +1 more
TL;DR: In this paper, the mass transfer correlations reported in this paper are similar to earlier heat and mass transfer correlation, but can be complicated by diffusion across the fiber wall and by alterations in fiber geometry.
