Veolia Water Solutions & Technologies, through its thermal desalination specialist SIDEM (Veolia WSTSidem), has been chosen to design and build one of the world's largest desalination plants in Saudi Arabia. Considered of national importance, the plant will provide 800 000 cubic metres per day of desalinated water to Jubail Industrial City and the Eastern Province of Saudi Arabia. Metso Automation has been chosen to deliver the 310 valves needed for this massive project. The contract awarded to Veolia Water and worth around US$945 million is for the complete design and build of the desalination plant. This forms part of a long term expansion plan for power and desalination capacity in the Eastern Province of Saudi Arabia.
The desalination plant will be based on SIDEM's unique multiple effect distillation (MED) process and will include 27 desalination units, each having a capacity of 29 630 cubic metres per day. The MED process is one of the leading technologies incorporated within the project. It recovers the exhaust heat from the power plant and uses it to evaporate sea water at low temperature. As its electrical consumption is low, it is the ideal solution for addressing the normally large energy consumption associated with desalinating seawater.
More than 300 Metso Automation valves were ordered for these desalination units, most of them being Jamesbury Wafer-Sphere butterfly valves ranging from 80 mm to 1100 mm diameter, with Neles valves Neldisc series LW et L6 and Finetrol complementing the offering. The first part of the delivery will take place in the first quarter of 2008. The project, which will be completed by 2010, is designed to serve an increasing population in the Eastern Province of Saudi Arabia, the country which holds the world's largest oil reserves.
