Multi Effect Evaporator/MVR
Multi Effect Evaporator is used for minimizing the emissions from chemical industry. It also recovers the DM water which can be further used in the process. Multi Effect Evaporator recovers the products present in water wash. In our Multi Effect Evaporator, water is boiled in a sequence of vessels and each vessel is placed at a lower pressure than the previous one. In this process only the first vessel requires external source of heat and the remaining ones gets heated with the vapor formation. Our Multi Effect Evaporator uses sensible heat in the condensate to preheat liquor that has to be flashed.
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 next, and only the first vessel (at the highest pressure) requires an external source of heat. While in theory, evaporators may be built with an arbitrarily large number of stages, evaporators with more than four stages are rarely practical except in systems where the liquor is the desired product such as in chemical recovery systems where up to seven effects are used.
