Effect of additive concentration on falling film absorption.

Summary

Certain alcohols enhance the absorption of water vapour in aqueous solutions of lithium bromide. The authors studied the effect of branched and linear additives on absorption for varying additive and brine concentrations. The additive concentrations were varied from 10 to 1000 parts per million in a vertical falling film absorber. The enhancement measurements show that 2-ethyl-1-hexanol and 1-heptanol enhance absorption at concentrations below their solubility limits. These results are significant, in that the presence of two liquid phases is not necessary for enhancement to occur.
