Tianjin SDIC Project
China’s Largest Desalination Plant
China’s SDIC (State Development and Investment Corporation) Tianjin power plant is a state-of-the-art facility located 200 kilometers northeast of Beijing. IDE have created a win-win concept for SDIC – the deployment of an advanced seawater desalination process that is powered by the electric plant’s waste heat, which, unless captured and re-used, would be discharged into the atmosphere. The system also recycles the post-desalination waste brine and uses it to create pure table salt.
CAPACITY: 200,000 m³/day
TECHNOLOGY: Multi-Effect Distillation (MED)
PROJECT TYPE: Engineering-Procurement-Construction (EPC)
LOCATION: Hangu, Tianjin, China
FOOTPRINT: 125m x 160m
COMMISSION DATE: 2010, 2013
CHINA’S DESALINATION LARGEST PLANT: 200,000 m³/day
WASTE HEAT UTILIZATION SYSTEM: The system is powered by waste heat generated by the Tianjin SDIC electricity plant, thereby reducing costs and minimizing the discharge of heat from the plant to the atmosphere.
CO-CREATION OF TABLE SALT: Using a new technology, the system sends its saline brine to evaporation ponds for production of pure table salt.
CLOSED SEAWATER CIRCULATION MODE: Unique technology eliminates dependence on external fresh water resources.
“IDE’s MED technology has enabled us to realize an environmentally-friendly power-seawater-desalination-salt production model. This helps us to minimize our environmental footprint while reducing our costs. We are proud of this world-class design and believe that it will serve as a model for other power plants throughout the world.”
