The sea water evaporation is realized by flash into multiple flash chambers each of them working at a different pressure. A cascade of stages is realized, through which the vacuum degree increases up to the last stage (the coldest stage).
Sea water is required in large excess as cooling medium, in order of the heat reject for Heat Balance closure, while only a portion of the total sea water demand is used as make-up water to the evaporator.
Each stage the condensing vapor release his heat to the sea water for preheating.
