Experience and Operating Feed Back After 7 Years of Operation of a 10,000 m3/D MED Plant
Previously published as part of The International Desalination Association (IDA) World Congress Proceedings, Tianjin-China 2013
Abstract: One of the key challenges in desalination and other types of water treatment is in investing in new technologies and using new techniques to offer low cost desalinated water to industrial clients and communities. Providing low cost desalinated water for processes and drinking water was one of the major goals of the project described in this paper.
This paper looks back at 7 years of operating feedback and presents design and construction challenges and features, operation and performance data for the 2 X 5,000 cubic meters per day (m³/day) Multiple Effect Distillation (MED) Thermal Vapor Compression Seawater Desalination units supplied on a Design-Build-Own-Operate and Transfer (DBOOT) basis to the Rabigh Desalination Plant project of Modern United Water Desalination Company (MUWDC) located in Saudi Arabia. The desalinated water is partially used as process water for the adjacent refinery and the other part of the production is used as potable water after the addition of post treatment chemicals.
The paper also presents information on the operation features adapted in the plant to minimize the life cycle cost of water during the 20 year operating contract. The cost of water is reduced by optimizing the selection of different materials used for the construction of the units, use of low cost steam available in the plant, and with the use of various design optimization features.
