Phase distribution of the surfactant 2-ethyl-hexanol in aqueous lithium bromide.

Type of article: Article

Summary

The work reported in this article was conducted to improve understanding of absorption enhancement in absorption chillers based on aqueous lithium bromide due to the presence of 2-ethyl-hexanol. Knowledge of the phase distribution of the surfactant in the vapour and liquid and on the surfaces is necessary for a clear understanding of enhancement physics. It was found that the concentration of alcohol in the vapour is a key variable in characterizing many processes in this system. A vapour surfactant theory of absorption enhancement is further supported by the results presented, which include estimates of liquid solubility, surfactant surface concentration and the corresponding surface tension, and vapour concentration.
