Abstract:

A preliminary design of a 20,000 gpd containerized indirect contact freeze desalinator was completed. The system consists of a freezer with a defrosting cycle wash column indirect contact melter and pumps, compressors, heat exchangers and controls necessary to make a complete system. At a nominal design point of 3.5 feed and at 70 F, power consumption is estimated to be 77 kw-hrkgal. The construction cost of a prototype unit is estimated to be 280.000. The system is designed to operate on virtually any type of feed water. Projected performance data is given for the system operating with feed salinities from .5 to 5 and feed temperatures from 40 F to 100 F. In addition to a system with a defrosted freezer, studies were conducted of a scraped tube freezer which indicated that both the capital and operating cost of that type of freezer would be much more expensive.
