The conceptual design of a commercial solar powered 6,000 m3/dayplant for desalting seawater is described and criteria used in the design and selection of equipment are discussed. The layout of the plant and the process flow diagrams are given with indication of the major performance specifications and a listing of important design parameters. The plant is designed for a generic site of characteristics common to specific sites in Saudi Arabia and the U.S., however, the design can be used for other sites in other countries. Modularity of the design also allows scaling the plant down to lower capacities appropriate for a pilot unit or for areas of low demand. Several measures have been taken to maximize the use of solar insolation and to reduce power consumption. Those include energy recovery,utilization of waste heat, and operating the desalination plant at low flow rate when the solar insolation is low. The plant design was optimized to give the lowest water product price and trade off studies are made to provide high reliability and low cost. A special simulation computer code is used for the cost analysis and for fine tuning the design parameters within the constraints of the performance specifications provided by the SOLERAS program.
