The solubility of H₂S and CO₂ in aqueous monoethanolamine solutions

Abstract

The solubility of hydrogen sulphide and carbon dioxide, respectively, in 2.5 and 5.0 N aqueous monoethanolamine solutions has been determined at temperatures of 40°C and 100°C. Partial pressures of CO2 ranged from 0.1 to 1000 psia, while partial pressures of H2S ranged from 0.3 to 650 psia. The results have been used, together with literature data, to calculate enthalpies of solution.

Solubilities of carbon dioxide in aqueous solutions of sodium glycinate

“…The reliability of the vapor-liquid equilibrium apparatus was tested by comparing the measured CO 2 solubility in aqueous 15.3 mass% MEA solution at 313.15 K with published data and our results compared well with the previously reported data [34][35][36] as shown in Fig. 1.…”

Stripping of carbon dioxide from monoethanolamine solutions in a packed column

“…The actual experimental data of Jones et al (1959), Lawson and Garst (1976), Lee et al (1974), Lyudkovskaya and Liebush (1949), Mason and Dodge (1936), Mdbauer and Mo~ghan (1%7), Munin et al (1969), and Nasir and Mather (1977) are compared with the correlation in Figure A-1. The experimental measurements cover a temperature range from 0°C to 140°C for MEA concentrations between 0.5 N and 9.5 Nand solution loadings less than 0.45, and include some 250 points.…”

CO2 Absorption Rate and Solubility in Monoethanolamine/Piperazine/Water

“…MEA is a relative strong base with a fast reaction rate, yielding a low CO2 concentration. A number of investigators have studied the solubility (12,15,16,23) and reaction kinetics (1,7,9,11,14) of CO2 in aqueous MEA.…”
