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:

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.
