A COMPUTER PROGRAM TO CALCULATE AND DESIGN SYSTEM OF NATURAL VACUUM DESALINATION BY USING EES SOFTWARE

Abstract

Potable water is the vital demand of human, especially in coastal or rural areas. The technology of natural vacuum distillation is simple, thermally driven, and of heat source of low temperature as solar thermal energy required. In this study, a computer program for design and analysis of the distillation system was developed. The program established by using EES software was compact and fast calculation. The program is inputted design parameters such as make-up seawater temperature, heat source temperature, ambient temperature, yield of the process. The program is to estimate heat transfer rates and areas of heat exchangers as well as
distillation performance
