Physical solubility of carbon dioxide in aqueous alkanolamines via nitrous oxide analogy
- Univ. of Newcastle, Callaghan, New South Wales (Australia). Dept. of Chemical Engineering
In the petrochemical and natural gas industry, the removal of carbon dioxide and hydrogen sulfide from process gas streams is commonly achieved by reacting these impurities with aqueous alkanolamines. Van Krevelen coefficients for protonated monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA), the carbamates of MEA and DEA, and the bicarbonate ion have been determined experimentally from measurements of the solubility of N[sub 2]O at 25 C and atmospheric pressure in aqueous solutions of these ions. Measured values different significantly from values recommended by others in the absence of experimental data. By analogy with N[sub 2]O, the solubility of carbon dioxide in the same solutions can be estimated.
