- Abstract
A model of a typical endoreversible desalination system of sea water is established and the minimum energy requirement for the system is optimized by using finite time thermodynamic theory. The heat exchange between the endoreversible desalination system of sea water and surroundings are delivered by two endoreversible Carnot heat pumps and three endoreversible Carnot heat engines. The minimum energy requirement for the system can be found by subtracting the power outputs from the power inputs. The results show that the minimum energy requirement for the distillation system depends on not only the properties of the input saline water, the output pure water and the brine water, but also the inherent features of the heat pumps and the heat engines, i.e. the total heat conductance of the heat pumps and of the heat engines. The results obtained herein are closer to those of practical system than those obtained based on reversible model.
