Abstract
A multistage evaporation system is proposed in which the first evaporator is heated via a jet wet washer with superheated, air-containing waste steam, for example of a drier. The product vapor of the first evaporator stage is fed via a mechanical compressor to a second evaporator stage for heating. The compressor ensures firstly a lowering of the dew point in the evaporator space of the first evaporator stage and secondly a temperature increase of the product vapor fed to the second evaporator stage for heating.
