Abstract

"An experimental method for measuring mass transfer rates at pressures above atmospheric has been developed for the case of continuous countercurrent evaporation through porous water-repellent membranes. The final developed equipment is suitable for operation under pressures up to 50 psig and at temperatures near the boiling point of 7% salt water when high flow rates are reached. Rates of evaporation of water through the membrane were measured, and the data and results were used to examine the effects of operating conditions on the over-all mass transfer resistance. Least squares equations for fitting the data were also obtained. Over-all mass transfer coefficients were found to be a strong function of pressures and to depend slightly on flow rates and the log-mean partial pressure of the stagnant air in the membrane. The experimental method should be useful for the study of evaporation through porous membranes for application to commercial sea water conversion"--Abstract, page ii.
