Hello, I now want to cancel the condenser that comes with the distillation tower in PROII, add a condenser myself, and then reflux to control the reflux ratio. How should I set it up and what models are needed? I made two processes myself. One method is to connect the tower to a condenser, add two logistics lines to the condenser outlet, and control the reflux ratio through the controller. However, the data table shows that there is no gas phase, liquid phase, or temperature in the tower. Another method is to connect a condenser out of the tower, then connect a flash tank, and then the flash tank comes back out. The data table shows the same results. What is the reason?
There is a problem with the simulation of the tower. The condensation refluxes into the tower, the flash tank should have temperature limits, and a splitter distributor is required. This process is generally difficult to converge.
I added a shunt later, but it still didn't work, still the same result.
This is not difficult. I have tried many such calculations.

Could you please give me some advice on how to do it?
1. It is easy to simulate the distillation tower by adding an external condenser. 2. It is easier to simulate the condenser using the module. What is the purpose of doing this? Practice to reduce simplicity to complexity * * ?
Double-click the tower. In the pop-up window, there is a cendenser at the top. Click it to remove the hook inside and there will be no condenser. In addition, the liquid phase pipe of the condenser needs to be split. A splitter distributor is needed, and an initial value of the tower top reflux can be calculated.
