Review of CO2 absorption using chemical solvents in hollow fiber membrane contactors

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.

Wetting phenomenon in membrane contactors – Causes and prevention

TL;DR: The impact of membrane wetting on mass transfer resistance and absorption efficiency, the effect of influencing parameters including absorbent (operational conditions, type and concentration) and membrane (hydrophobicity, pore size and porosity) properties on wetting phenomenon, as well as different methods to prevent membrane wetness, along with their advantages and drawbacks are discussed in detail as discussed by the authors.
