Preliminary Design of an Experimental Containerized Freeze Desalination Unit.
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-hr/kgal. 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.
