New absorption liquids for the removal of CO2 from dilute gas streams using membrane contactors
TL;DR: In this article, a new absorption liquid based on amino acid salts has been studied for CO2 removal in membrane gas-liquid contactors, and a numerical model to describe the mass transfer accompanied by multiple chemical reactions occurring during the absorption of CO2 in the liquid flowing through the hollow fiber was developed.

H. Hikita,S. Asai,T. Takatsuka +2 more
TL;DR: In this paper, an analytical solution based on penetration theory has been derived for the case where the chemical equilibrium constants of the first and second step reactions, K1 and K2, are very large and the diffusivities of all species are equal, and the reaction factor in this case has been shown to be a function of the equilibrium constant ratio K1/K2.
