Falling film evaporators have been designed and developed by Exergy to be used mainly in conjunction with our Exergy Dryers. The low pressure steam from the Exergy dryer is used to generate clean steam to be used in steam turbines for electricity production, process heating etc.
Other applications such as evaporation of leachate have been identified for this technology. A combination of falling film and forced circulation evaporators has been used where large volumes need to be concentrated to very small residual volumes such as in ethanol plants used in the sugar industry.
Key Benefits of the Exergy Falling Film Evaporator:
Low temperature difference makes it economical for MVR operation and multiple effect
Small footprint
Low maintenance due to few rotating parts
Used as re-boiler after Exergy Superheated Steam Dryer
