    diagram of a double-effect falling film evaporator. Condensing vapors from flash tank B1 heat evaporator A2. •1=feed •2=product •3=steam •4=vapors. In chemical engineering, a multiple-effect evaporator is an apparatus for efficiently using the heat from steam to evaporate water. [1]

  3. Evaporator - Wikipedia

    en.wikipedia.org/wiki/Evaporator

    The energy consumption for single-effect evaporators is very high and is most of the cost for an evaporation system. Putting together evaporators saves heat and thus requires less energy. Adding one evaporator to the original decreases energy consumption by 50%. Adding another effect reduces it to 33% and so on.

  4. Mechanical vapor recompression - Wikipedia

    en.wikipedia.org/wiki/Mechanical_vapor_recompression

    Multiple effect evaporation (MEE) Thermal vapor recompression (TVR) (also known as thermocompression) A combination of the three methods may be used depending on the process. For instance, a 3-effect evaporator circuit may be installed using MVR to transfer heat.

  5. Climbing and falling film plate evaporator - Wikipedia

    There are several design variations that are commonly used in industrial field. These include single-effect and multiple-effect evaporators. The choice of evaporator design is dictated by constraints of the process. Fundamentally, there are four factors involved in designing this evaporator: prevention of nucleate boiling; short residence time;

  6. Cascade refrigeration - Wikipedia

    A two-cycle cascade refrigeration process schematic diagram. A cascade refrigeration cycle is a multi-stage thermodynamic cycle. An example two-stage process is shown at right. (Bottom on mobile) The cascade cycle is often employed for devices such as ULT freezers. [1]

  7. Circulation evaporator - Wikipedia

    en.wikipedia.org/wiki/Circulation_evaporator

    The best way to achieve high economies (which can be well over 100%) is to use multiple effect evaporator, whereby the vapour from one evaporator – or effect – is used to heat the feed in the next effect, where boiling occurs at lower pressure and temperature [3] Thermo-compression of the vapour, whereby the vapour will condense at a ...

    Gas furnaces, used for heating and hot water, account for roughly 15% of annual U.S. residential energy use, according to DOE. The rule is proposed to take effect in 2029, and it would effectively ...

  9. Vapor-compression evaporation - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_evaporation

    A vapor-compression evaporator, like most evaporators, can make reasonably clean water from any water source. In a salt crystallizer, for example, a typical analysis of the resulting condensate shows a typical content of residual salt not higher than 50 ppm or, in terms of electrical conductance , not higher than 10 μS/cm .
