✦ Synopsis

Absorption of CO2 in aqueous solutions of alkanolamines is of considerable commercial importance. The reversible nature of the reaction always results in equilibrium partial pressures of CO*. This is very important to process design engineers while designing the top parts of absorbers to meet the desired specifications. It is shown that the total equilibrium (final equilibrium) may not be established on the top theoretical stage, so equilibrium data must be used judiciously.

A thermodynamic model is proposed for the solubility of the acid gases (H,S and CO,) in alkanolamine solutions. The model is based on the extended Debye-Hiickel theory of electrolyte solutions. Predicted partial messures of the acid gases over monoethanolamine solutiom are in good agreement with exp

The reaction kinetics of carbon dioxide with four alkanolamines of industrial importance (MEA, DGA, DEA, and DIPA) have been investigated with the aid of the stopped-flow technique, allowing the determination of rate constants for carbamates formation. The constants obtained for MEA at 20°C and 25°C

Experiments have been carried out on the absorption of carbon dioxide in monoethanolamine(MEA) aqueous solutions. A laminar liquid jet absorber was first used, and the results obtained (which covered the contact time range between 0.02 and 0.0'7 set), showed good agreement with the penetration theor

## Abstract In Parts 1–5 of this paper^1^ charts were given which showed the vapour pressures of ammonia and carbon dioxide over aqueous solutions at 20° and 40°. Measurements of the vapour pressure of ammonia have now been made at 90° in order to provide data for calculating the efficiency of ammo
