How to simulate falling film evaporators using HTRI
Thread Content
Hello, experts: In alkali evaporation, a counter-current falling film evaporator is used to evaporate 32% wt of alkali to 50% alkali. How can HTRI be used to simulate the falling film evaporator? Could the expert provide a general idea? Thank you!

The key to a falling film evaporator is the mechanical design of the falling film head; the other parts are no different from those of ordinary heat exchangers.
