Abstract:In this work the electrolyte equation of state as developed previously for the system MDEA-H 2 O-CO 2 -CH 4 [Huttenhuis et al. (2008), pp.99-112] was further developed for the system MDEA-H 2 O-H 2 S-CH 4 . With this thermodynamic equilibrium model the total solubility of hydrogen sulfide and the speciation in aqueous solutions of N-methyldiethanolamine can be described quantitatively. The model results were compared to experimental H 2 S solubility data in aqueous MDEA in absence and presence of methane respectively. The application of equation of state models for this kind of acid gas -amine systems is a rather new development in the literature. An accurate description is difficult for this kind of complex systems with significant amount of both molecular and ionic species present in the liquid phase. The Schwarzentruber's modification of the Redlich-Kwong-Soave EOS with a Huron-Vidal mixing rule is used as molecular part of the equation of state and ionic interactions terms are added to account for non-idealities caused by these interactions. With the new developed model a comparison with experimental data as presented was made.

“…Aqueous alkanolamines such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and 2-amino-2-methyl-1-propanol (AMP) have been widely used chemical absorbents for removal of acid gases (CO 2 , H 2 S) [5][6][7][8][9][10]. Especially, aqueous MEA solutions have been widely used as an industrially important absorbent because of its rapid reaction rate, the low cost of the solvent, the thermal stability, and low solubility of hydrocarbons as well as high alkalinity.…”
