Abstract

The international demand of water increased compared to the available water resources due torecent development water resources for different uses. In many areas especially in Arabian GulfAreas, a shortage of portable water. This study deals with design a model to combine the multi effect desalination water (MED) with the steam power plant. Using the exhaust waste heat of the power plant to heat the sea water. The model has been based upon various heat and mass transfer equations. Taking in consideration all requirements of making available safe drinking water for requirement. The waste heat of the exhaust gases of power plant is captured before exhausting it to the atmosphere and transferred to salty water. The temperature of salty water rise to level 90C to130C. This is ideal temperature for desalination in multiple effect distillation MED plant. The hot salty water then passes through a flash into the evaporator then condenses on the condenser tube bank, and internal heat recovery is achieved by transferring its heat of condensation to the sea water feed that is thus being preheated.In this study selective an exist steam power plants, combine with MED to produce 1000 m3/day to15000 m3/day drinking water from salty water. desalination.
