Title: Design of a solar power plant for freeze desalination

Abstract

A solar-powered seawater desalination plant recently began operating in Yanbu, Saudi Arabia. Design and construction were funded by SOLERAS, a joint effort by the United States and Saudi Arabia to further the development and commercialization of the solar energy. The plant consists of 18 parabolic dish solar collectors with a total reflective surface of 1,445 m/sup 2/ and a thermal output of over 1 MW. Its rated output is 200 m/sup 3/ per day of fresh water. The collectors heat a synthetic heat transfer fluid, Syltherm 800. The heated fluid, in turn, charges a molten salt buffer system. On demand, the molten salt is pumped from a two tank storage system through a steam generator, producing superheated steam. The steam is expanded through a steam engine which provides the shaft power that drives the compressors of the desalination system. This paper describes the solar plant and some of the trade off studies that led to the final configuration. Important trade off studies included: the choice of heat transfer fluid and the thermal storage medium. In addition, the selection of solar collectors was an interesting exercise.
