Assembled falling-film evaporation

A combined falling-film evaporating process features that a tubular falling-film evaporator used when the internal temp is higher than or equal to 100 deg.C or the alkali (Na2Ok) concentration is higher than or equal to 190 g/l and a plate-type falling-film evaporator used when the internal temp is...

Zusammenfassung:A combined falling-film evaporating process features that a tubular falling-film evaporator used when the internal temp is higher than or equal to 100 deg.C or the alkali (Na2Ok) concentration is higher than or equal to 190 g/l and a plate-type falling-film evaporator used when the internal temp is lower than 100 deg.C and the alkali concentration is lower than 190 g/l are combined to evaporate the raw liquid and obtain the cyclic mother liquid.
