"The economics of desalination by evaporation through porous, water-repellent membranes has been studied in this investigation. Using reasonable assumptions this desalination process was found to be economical with the principal advantage being the simplification of multi-stage flash-type evaporation. Based on this process, two different methods were designed and studied by means of computer calculations for a 10 million gallons product water per stream day desalting plant. One method was based on a membrane evaporator and a heat exchanger and was designated Method I; and a combined evaporation-heat exchanger system was designated at Method II. The major factors affecting the economics were the temperature differences utilized and the maximum and minimum temperatures of evaporation. Computer calculations on these methods were used to study process economics under a number of possible conditions. Also experimental runs were made to determine the useful life of the required porous membranes"--Abstract, page i.
