BUSINESS Acciona to build Sembcorp's Fujairah expansion Singapore's Sembcorp Industries has signed a 20-year water purchase agreement with the Abu Dhabi Water & Electricity Company (ADWEC) which will enable it to expand its Fujairah 1 Independent Water & Power Plant (IWPP) by 30 MIGD (136,000 m3/d). Sempcorp has also awarded a contract to Spain's Acciona Agua and Acciona Infraestructuras to build the seawater reverse osmosis (RO) expansion. Acciona will design, build and provide seven years' operation and maintenance services for the expansion project that will make this part of the hybrid plant the largest RO desalination facility in the Middle East. Under the water purchase agreement through Sembcorp's joint venture Emirates Sembcorp Water & Power Company (ESC) with the Abu Dhabi Water and Electricity Authority, the output from the expansion will be sold to ADWEC for 20 years, starting from its operational date. This is in addition to the existing 22-year power and water purchase agreement for the current water and electricity output from the Fujairah 1 IWPP to ADWEC. The expansion is expected to cost approximately US$ 200 million. Sembcorp's equity investment of US$ 80 million will be funded through internal resources. The expansion will enhance Sembcorp's total seawater desalination capacity in the UAE from 130 MiGD (591,000 m3/d), of which 67.5 MiGD (307,000 m3/d) will be produced using reverse osmosis. The remainder is produced using multi-stage flash. "One of the most innovative aspects of this expansion project is its ability to recover seawater discharge from the existing multi-stage flash facility for reuse as part of the seawater feed for the entire Fujairah 1 IWPP," said William Chang, executive managing director of ESC. IDE sells more MVC units to Chile Austria's Andritz Energy & Environment has placed a purchase order for two more Mechanical Vapor Compression (MVC) desalination units from IDE Technologies for AES Norgener, a 280 MW coal-fired power station in Chile. For over 15 years, IDE's thermal desalination units have been in operation at the power plant located in Tocopilla. The new MVC units will yield an additional capacity of 1,200 m3/d of desalinated seawater to be used for the Flue Gas Desulphurization process, which will minimize gas emission, meeting high standard environmental regulations. With highly efficient evaporator condensers, IDE's units will result in increased water output while requiring low energy levels and a small environmental footprint. "The depletion of water sources is a huge problem in a growing number of regions all over the world, and Chile is no exception," said Avshalom Felber, CEO of IDE Technologies Ltd on 22 January 2013. "We are proud that our advanced technology and eco-friendly approach can help organizations like Andritz provide a sustainable and reliable solution to better serve customers such as AES Norgener." ABB to supply switchgear to Yanbu 3 desalination ABB has won an order to design and deliver 420 kV high voltage gas insulated switchgear that will facilitate the supply of power to the Yanbu 3 desalination facility in Saudi Arabia and support the grid integration of a new 2.5 GW power generation plant. These new facilities are being developed by the Saline Water Conversion Corporation (SWCC), the country's government agency responsible for desalinating seawater and the second largest electric power producer in the country. The order was received from the Al Fanar Group, a leading engineering, procurement and construction company. The multi-stage flash desalination plant, which is being built by Doosan and is scheduled to be commissioned in June 2014, is located in Yanbu Industrial City. The plant will have a capacity to produce 550,000 m3/d. Saudi Arabia is the world's largest producer of desalinated water and SWCC operates 27 desalination plants producing more than 3 million m3/d of potable water. | 8 | Desalination & Water Reuse | February-March 2013 BEL pressure vessels for Colombian desalination Pressure vessels for the 79,500 m3/d produced-water desalination plant being designed and built for Pacific Rubiales Energy Corp (PREC) in Columbia are to be supplied by BEL Composites. BEL was chosen by Nirosoft Industries, which is designing and building the plant. The pressure vessels will be supplied by Spanish subsidiary BEL Composite Iberica SL from its production facility in Murcia, Spain. The vessels are equipped with highgrade steel side-ports in a state-ofthe-art multiport arrangement. Nirosoft will set up a greywater desalination facility especially suited to deal with the recycling of water used in crude production. The plant will output 79,500 m³/day for PREC, the largest independent oil and gas exploration and production company in Colombia. Hitachi signs Indian water purchase accord Japan's Hitachi announced on 13 January 2013 that its consortium with Hyflux of Singapore had concluded a water purchase agreement with Dahej SEZ Ltd (DSL), the management company of the Dahej Special Economic Zone (SEZ) in Gujarat, India, for water from its proposed desalination plant in the SEZ. The consortium now intends to obtain environmental assessment approval and meet other requirements to successfully implement the project. The project involves construction of a 336,000 m3/d seawater desalination plant in an industrial park within Dahej SEZ in Gujarat and stable supply of industrial water over a period of 30 years (including the construction period). It is one of the Delhi-Mumbai Industrial Corridor Projects being promoted jointly by the Japanese and Indian governments, involving the construction of industrial parks between Delhi and Mumbai (approximately 1,500 km) utilizing private sector capital. The consortium will conduct discussions toward the final agreement with DSL planned for around fall 2013, after obtaining environmental assessment approval and achieving the financial close.
