Hi all,

 

I am working on a batch distillation project in ChemCAD, specifically the controls. The simulation already has the the column, condenser, valves and other piping/equipment modeled. I want to control the reflux rate using a level control valve that maintains a constant level in a condensate receiver just after the condenser.

 

To this point I have been able to control the flow through the control but to get that to work I had to calculate the inlet and outlet pressure of the valve by hand and input them on the valve in the simulation. I have not figured how to make anything in the system read the level in the tank.

 

How do I need to set up the valve and pid to control the level in the condensate receiver rather than specifying the valve info?

 

Thanks!

Hi  Jkershner

 

For setting up a control logic in Batch distillation not possible, so please do in dynamic operation of batch distillation CCReact, column, condenser, here you can define control logic.

 

Thanks
