✦ Synopsis

The Exchange Crystallization (E-C) freeze desalination process is a u and innovative approach to the problem of Sea water desalting . Utilizing solidliquid phase transformations to accomplish the freezing, the E-C plant avoids both costly corrosion problems and the mechanical intricacy of vapor handling .

The use of exchange engines as energy recovery devices permits the E-C process to compare favorably with other freezing processes and to be substantially lower than evaporation processes in the area of energy con :,umption . On both an energy and capital cost basis, the E-C process is one of the most attractive desalination processes presently available .

The operational problems encountered in the E-C process should be solvable by utilizing existing technology . Development work is presently under tray to eliminate the problems which have been i dentified . i n the near future, the E-C process will prove its potential for economic sea water desalination .
