SGX-listed engineering service Boustead Singapore Limited announced on Tuesday that its wholly-owned subsidiary, Boustead Salcon Water Solutions Pte Ltd has been awarded a major multi-million dollar contract from one of the world?s largest employee-owned EPC corporations to design and supply water and wastewater treatment facilities for the balance of plant (BOP) scope of a 2,000MW ultra supercritical coal-fired thermal power plant located in Central Java.
The water treatment facilities consist of a 15,000 cubic metres/day dissolved air flotation with filter (DAFF), seawater reverse osmosis desalination, brackish water reverse osmosis desalination, remineralisation and demineralisation plants.
The wastewater treatment plants involve ash, coal and process treatments. A key wastewater treatment process will be the ammonia removal system, which employs an advanced catalytic oxidation process (COARS) to meet the stringent environmental discharge standards. Ammonia wastewater from the condensate polishing plant will be first stripped off ammonia gas and preheated before passing through the catalytic oxidation process, so that the wastewater can be further broken down into harmless and odourless nitrogen and steam, leaving no residual toxic by-product.
The Power Plant will be the first in Indonesia to employ ultra supercritical technology for high-efficiency power generation fuelled by domestic sub-bituminous coal. Through a reduction in coal consumption and greenhouse gas emissions, the ultra supercritical coal-fired power plant is much more energy-efficient and environmentally-friendly as compared to existing traditional coal-fired power plants. Under a power purchase agreement, the Power Plant will supply electricity to Indonesia?s national power corporation, PLN for a period of 25 years.
The power plant, which will be built in Pemalang , Central Java is owned by a consortium of Japan's Electric Power Development Co (J-Power) , Itochu Corp and Indonesian coal miner Adaro Energy.
