Višekriterijumska optimizacija postrojenja za proizvodnju demineralizovane vode iz toplih izvora

In this paperwork is presented installation for water desalination from hot water sources, which is based on decreasing pressure of hot water, by water ejector, to achieve evaporation. The goal is to find optimal thermodynamic states of process and working fluid. Thus multiobjective optimization based on NSGA II algorithm is performed. Investment cost and profit are two goal functions that have been chosen. Additionaly profit is evaluated for the period of the whole year, as a consequence of seasonal variations of water temperature at the inlet. Besides it is showed that investment cost and profit of installation are contradictory goal functions. Moreover presented method allows investors to make rational decision by choosing installation from obtained Pareto front.
