Hengyi (Brunei) petrochemical construction 3×12500 tons/day of low temperature multi-effect seawater desalination project is so far the largest scale exported EPC project. As LT-MED technology is first time ever converged with hot water flashing technology to produce distillate, the cost is greatly reduced by using low quality hot water as heat resource for distillating in this project. Leading seawater desalination technology keeps Shanghai electric expanding the market share and serves better.
