Solubility of carbon dioxide in methyldiethanolamine + methanol + water
- Univ. of Alberta, Edmonton, Alberta (Canada). Dept. of Chemical Engineering
Aqueous solutions of methyldiethanolamine (MDEA) are attractive solvents for the selective removal of H{sub 2}S from process stream containing CO{sub 2} and hydrocarbons. The solubility of CO{sub 2} in a mixed nonaqueous solvent of methyldiethanolamine MDEA and methanol has been measured at 40 C. The results are compared with the solubility of CO{sub 2} in pure methanol. The solubility of CO{sub 2} has also been obtained at 40 and 100 C in an aqueous mixed solvent consisting of methanol (40 mass %), MDEA (40 mass %), and water (20 mass %) at partial pressures of the acid gas up to 7.04 MPa. The solubility results are compared with the nonaqueous mixed solvent results and previously reported data for aqueous methyldiethanolamine.
