Stainless Steel Multiple Effect Evaporator, Color : Silver

The Multiple Effect Evaporator (MEE) 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. Multiple-effect evaporation commonly uses sensible heat in the condensate to preheat liquor to be flashed. In practice, the design of liquid flow paths can be somewhat complicated in order to extract the most recoverable heat and obtain the highest evaporation rates from the equipment. We can supply multiple-effect evaporation from two effects to six effects. Our MEE system capacity ranges from up to 300 KLD. We can also supply multiple effect evaporators with Thermo compressors to get good steam economy & reduce the cost. Application MEE is used in the ZLD Plant, After the 3rd Stage RO Plant, RO Reject Water TDS becomes very high. For every High TDS water, we cannot dispose of this water anywhere. Evaporation is the only option for this kind of high TDS water.
