Title: Equilibrium solubility of acid gases in diethanolamine and monoethanolamine solutions at low partial pressures

Abstract

Aqueous monoethanolamine (MEA) and diethanolamine (DEA) solutions are used extensively for the removal of H/sub 2/S and CO/sub 2/ from gas streams. Advantages of the use of these particular chemical solvents include high reactivity, low cost, ease of reclamation, low absorption of hydrocarbons, and relatively high capacity at low acid gas partial pressures. The rational design and operation of MEA and DEA treating processes requires data for the equilibrium solubility of H/sub 2/S and CO/sub 2/ in the treating solutions over the wide range of acid gas partial pressures encountered in operating units. There has been a lack of data for low acid gas loadings. Low partial pressure data determined for the equilibrium solubility of H/sub 2/S, CO/sub 2/, and their mixtures in 2.0 kmol M/sup -3/ (20.5% by wt) DEA and 2.5 kmol M/sup -3/ (15.3% by wt) MEA solutions are presented. 20 references.
