I want to use the distillation module in PRO/II to simulate an extraction tower – how should I create the streams? How should the rest be set up?

The last edit to this post was made by longkui1990 on 2011-12-24 at 14:51, for example, using water to extract acetic acid from toluene
When placing the tower, the top condenser and bottom reboiler can be removed, and then it can be connected.
The stream diagram is similar to that of an absorption tower; the thermodynamic approach uses NRTL, a two-phase system, and the algorithm chosen is liquid-liquid, with condensers and reboilers being omitted
Give it some support; I also need to simulate an extraction tower
For extraction columns, a simple column is sufficient, with a condenser at the top and a reboiler at the bottom. Thermodynamic methods generally use the NRtl liquid-liquid model, which achieves good convergence in simulations, but does not allow for hydraulic calculations.
Thank you all for your answers; I am also working on simulating extraction!
Use a distillation column; do not select condensation or reboiling, and the other settings are similar to those of a distillation column
I’m a beginner, I’m learning*, thank you all
