What mode is best for simulating a distillation column with only a distillation section?
Thread Content
During distillation simulation, when there is only a distillation section and no stripping section – that is, feed is added at the bottom of the tower while product is taken out from the middle and top of the tower – what model should be used? Could everyone please help?
One can first use DSTWU for a straightforward calculation to obtain certain operational parameters such as the minimum reflux ratio and the number of theoretical plates, and then use radfrac for further calculations. If the conditions are sufficient throughout, it is also possible to use radfrac directly for the calculations.
You can simply use Radfrac for simulation.
It should be an intermittent process; you can try batchfrac for intermittent simulation. I’m not sure if that’s correct Hehe
The bottom of the tower needs to discharge material; otherwise, there will be an imbalance
