Doosan Heavy Industries announced on 28 January 2011 that it would be building three of the eight desalination evaporators required for the giant Saudi Arabian Ras Azzour desalination plant at its Vietnam subsidiary, Doosan Vina.
Work on the three 91,000 m³/d multi-stage flash (MSF) units will begin shortly. Doosan Vina shipped its first MSF unit to the United Arab Emirates in 2009.
The Ras Azzour project, for the Saline Water Conversion Corporation, will be a hybrid facility with 160 MIGD (727,000 m³/d) evaporation and 67.5 MIGD (307,000 m³/d) reverse-osmosis capacity. It will supply water from the Gulf to 3.5 million people in the Riyadh area.
Doosan will carry out design, manufacturing, installation and commissioning of the entire process , which is scheduled be completed by the end of 2014.
