Some of the key technical problems inherent in the design of equipment for the absorption, freezing, vapor-compression process for the production of pure water from salt water were investigated in laboratory studies. These included the comparison of various solvents for water vapor in the freezer-absorber unit, the determination of water mass transfer rates into concentrated salt solution in the refrigerated absorber, and the measurement of mass transfer coefficients for the absorption of water into a solvent stream that flows over horizontal tubes. The results showed that changes of the solvent can have only a small effect on the power required, that the resistance to heat transfer in the absorber has a greater effect than the resistance to mass transfer. Accumulation of air in the absorber vapor can be important.
