Résumé

This article presents the results of a series of experimental tests about the absorption of water vapour by an aqueous lithium bromide solution over a bundle of 14 smooth tubes, using an alcohol (2-ethyl-1-hexanol) as surfactant. It follows the same multi-factorial methodology used in a previous article, in order to compare with the experiences without the alcohol. The study reveals that the 2-ethyl-1-hexanol strongly affects the hydrodynamics and the heat and mass transfer, as is already known. In the conclusions a comment on how this could be used in practice is also done and some further research proposed, as for instance, the implication, or not, of the Soret effect in the inter-phase dynamics of the surfactant (2-ethyl-1-hexanol in our case) for aqueous lithium bromide solutions.
