A) Evaporator

Multi Effect Evaporator :

Falling Film Evaporators are used for processing liquors, which are sensitive, have a high rate of specific heat transfer, particularly for non-crystalline solutions. The liquid to be evaporated is evenly distributed on the inner surface of a tube. The liquid will flow downwards forming a thin film, from which the boiling/evaporation will take place because of the heating media such as steam, thermic oil, hot water etc.,

Falling Film Evaporators :

Falling Film Evaporators are available for capacities ranging from 100kg/hr to 30,000kg/hr.

Forced Circulation Evaporator :

Forced Circulation Evaporator is used if boiling of the product on the heating surfaces is to be avoided due to the fouling characteristics of the product, or to avoid crystallization. The flow velocity in tubes must be high, and high capacity pumps are required. In Forced Circulation Evaporator plant, the solution to be evaporated is circulated by circulation pump through the heat exchanger tubes with high velocity from bottom to the top. The vaporization takes place in the vapour head, where the vapour and liquor are separated by gravity and / or by centrifugal force.

B) Agitated Thin Film Dryer

Agitated Thin Film Dryer is a heat transfer equipment manufacturing and supplying.
In Agitated Thin Film Dryer, a thin layer of high TDS solution or Mother Liquor of waste water is distributed on
the Heating Surface of the ATFD Inner shell. In the jacket steam is supplied for heating of the same liquid. Solid
reaches the bottom having less than 5% moisture (depends on the product’s physical properties).

C) Stripper Column

In this system we can remove only low boiling solvent or low volatile solvent have boiling point less than 100°C. Low boiling solvent mainly present in Pharmaceutical, Pesticide, Chemical Industries etc., are methanol, ethanol, acetone, MDC, Acetonitrile etc. From stripper, low boiling solvent form effluent water recover from top side of the stripper column and condensate into condenser with some water traces.
If high boiling solvent present than it will be comes bottom of stripper and it will be transfer into MEE followed by ATFD. If high boiling solvent present in MEE feed and it can Azetrope with water than COD value will be come around 1500 to 2000 PPM in MEE Condensate water and if it’s not done. Azetrope with water than it will be come in ATFD salt.
