Research on optimization of power and water cogeneration system with LT-MED for seawater desalination
摘要
Abstract
On the basis of mass and heat energy balance of low temperature multiple-effect distillation (LT-MED) seawater desalination system, the optimization mathematical model of power and water cogeneration system with parallel/cross flow is developed in which condensed water flash distillation and seawater preheating are considered. The minimum cost of unit water is the optimization target. The optimization model of power and water cogeneration system is solved and analyzed by computing program which is carried out with Matlab toolboxes. The influence of number of effect, the amount of heating steam, system scale on the cost of unit water is analyzed. In the meantime, the costs of unit water with power and water cogeneration, equal temperature difference design with power and water cogeneration and equal temperature difference design with no power and water cogeneration are compared. The results indicate that the cost of unit water with power and water cogeneration is 87. 54% lower than that of equal temperature difference design with no power and water cogeneration with the same parameters. Power and water cogeneration is an effective way to reduce the cost of unit water.关键词
