Title: Vapor-liquid equilibrium of carbon dioxide in aqueous mixtures of monoethanolamine and methyldiethanolamine

Abstract

Aqueous solutions of alkanolamines are used to separate carbon dioxide and hydrogen sulfide from gas streams. Data for the distribution of carbon dioxide between the vapor and aqueous solutions of four mixtures of monoethanolamine (MEA) and methyldiethanolamine (MDEA) have been obtained at 25, 40, 80 and 120 C over a range of pressures from 100 kPa to 20 MPa. Partial pressures of CO[sub 2] ranged from 0.001 to 19,930 kPa. Enthalpies of reaction of CO[sub 2] in the solutions have been calculated from the solubility data.
