    Is the number of stage constant? When the components in the system change?

    Hi everyone, If I find the number of stage for the test run for Benzene Toluene unit and I find that the number of equilibrium stage should be 50 stages. If I turn the system into the extractive distillation. To separate Benzene and other non-aromatic components by using the solvent, NFM...

    Help please.. The actual reboiler temperature is higher than the simulation

    Dear everyone Now, I'm simulating the pilot extractive distillation column which employs NFM to capture toluene. The reboiler is an internal reboiler and electrical wire is used to provide heat instead of heating fluid. The bottom outlet temperature is 183 C in the simulation that give the...

    Does the reflux divider represent the reflux ratio (L/D) ?

    Dear StoneCold Thank you very much

    Does the reflux divider represent the reflux ratio (L/D) ?

    Dear everyone I am trying to simulate the pilot distillation column in ASPEN plus. This column doesn't have a reflux drum, it employs a reflux divider instead. I'm not sure that the reflux divider can represent the L/D ratio or not because R/W ratio in the reflux divider operation represents...
