Potable water within significant areas of the nations of the Arabian Gulf region is most frequently manufactured (cogenerated) along with electricity. The most economic process has been Multi- Stage Flash whereby the surplus thermal energy of the power generation process is used to “distill” brackish or sea water. Other methods that depended on electrical energy such as Reverse Osmosis and Electrodialysis have traditionally been too expensive for widespread use. Dramatic improvements in osmotic membranes have made R/O a competitive technology and as a result changed the requirement for co-location of electrical generation and water production. The paper presents a detailed modeling structure with which to evaluate alternate business investment opportunities for production of water. This paper reviews the alternative technologies, their electrical requirements and provides a detailed business case analysis for the development of distributed desalination facilities in both Saudi Ara...
