Multiple-effect distillation - Wikipedia

The multiple effect distillation process uses a steam heat source and a series of evaporators at successively lower pressures to create water. The reverse osmosis process uses membranes to separate the pure water from the brine. The conventional case would use steam from the bottoming cycle of a natural gas combined power cycle as the steam source.

Multiple-effect evaporator - Wikipedia

Multiple-effect evaporator - Wikipedia

A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used to heat the .
