✦ Synopsis

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 theory equations as well as with the kinetics of the mechanism of the chemical reaction which presumably takes place in the liquid phase.

Eventually a disk column absorber was used. The results were reproducible, and have been correlated in compact form by an empirical equation. Interpretation of the data on the basis of the penetration theory equations appears to be only partially successful.

RBsum&Des

experiences ont CtC effectuees sur l'absorption de gaz carbonique dans des solutions aqueuses de monothaenohunines (M E A). On a d'abord employ4 un absorbeur a &oulement liquide laminaire et les msultats obtenus (comprenant le temps de contact compris entre 0,02 et 0,07 see) ont CtC en accord avec les equations de la theorie de la pen&ration ainsi qu'avec la cinetique du mecanisme de la reaction chimique qui a probablement lieu en phase liquide.

On a, Cventuellement, utilise une colonne a disques.

Les r&ultats sont reproductibles et ont ettt rassembles sous forme d'une equation empirique. L'interpmtation des doMese, fondee sur les equations de penetration apparait comme n'etant que partiellement satisfaisante.
