falling film evaporator 1

[Orzelgorskiego]

Could somebody explain more precisely how to determine the number of stages for multiple installation of evaporators. Maybe we can use an example.

I have stcickwater flow of 4800kg/hr and I would like to evaporate 3200kg/hr .
I have residueal vapour of 1800kg/hr which will go to the evaporator.

How many stages should I use? I, II or III?

Thank you

Go to a company that designs and builds these. It is more complicated than that.
