TLDR
In this paper, a hollow fiber membrane contactor is used to separate CO2 from a gas stream, which is a promising alternative to conventional techniques such as column absorption, and the major advantages of the membrane absorption are the larger interfacial area, better device-modularity and more operational flexibility.About:

Evaluating hydrodynamics in a bioreactor with liquid phase dispersion in the gas phase
TL;DR: In this article, a specially shaped bioreactor has been designed, built and operated to increase the mass transfer coefficient, which was achieved when the liquid flow rate, the shower holes diameter, aeration velocity and middle part height of the bioreactors were 280 mL/min, 2 mm, 0.03 vvm and 60 cm, respectively.

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.

Microporous hollow fibers for gas absorption. I. Mass transfer in the liquid
Zhang Qi,Edward L Cussler +1 more
TL;DR: In this paper, a theory for the operation of hollow fiber membrane modules is developed, and mass transfer coefficients in the liquid phase are investigated, and the results show when the advantage of the increased area is greater than the disadvantage of the membrane resistance.
