The patented tube type falling film CS Evaporator (Condensate Stripping Evaporator) is designed for good heat transfer, low pressure drop and high secondary condensate quality.
The good heat transfer is due to countercurrent flow arrangement, where the liquor flows downwards inside the tubes and steam upwards outside the tubes. In addition, the patented Grid Baffle construction gives minimum internal pressure drop and good support for the tubes. Condensate flows freely on tubes in contact with upwards flowing vapor. This results in excellent secondary condensate segregation, methanol rich foul condensate and good quality secondary condensate.


Complete counter current flow
Built-in desuperheating for vapor
Excellent secondary condensate

Due to the small pressure drop in the Grid Baffle construction, CS Evaporator technology creates a lot of opportunities for capacity increases at existing evaporation plants.
