Hi,

 

I have a 4-effect falling film evaporator system. I want to increase the capacity of the multiple effect evaporator so as to run it at higher feed flow rate. I want to know what parameters I can change and basically approach this. Is there a maximum capacity of the MEE? Also how can I find out the heat transfer coefficient for falling film evaporator?

 

Thanks

Is there a flooding condition for falling film evaporators?

Hi ,

My understanding :

Thin film means very good distribution of the liquid to prevent flooding and rupture of the film along the pipe  . The thickness of the film is key for heat transfer .

 

You may find answer to your query in the attached document.

 

 

Hope this helps.

Hi,

 

I also need to know how can I calculate the residence time in this evaporator system. I actually have a pasteuriser in line with evaporator and there is Flow diversion valve that recirculates product if temperature falls below a certain point in pasteuriser. I need to set the control measure for the FDV and I think that will require the residence time.

 

Thanks.
