Aspen pseudo-binary gas-liquid equilibrium phase diagram

This post was last edited by The man is 21 years old on 2017-7-28 at 20:44. There is a propanol-methanol system, in which the propanol content ranges from 0 to 1. I want to know what the gas-liquid equilibrium curves for propanol and methanol will be when water is added at a mass ratio of 1:1 or 2:1 (water to propanol-methanol mixture). Does anyone know how to use ASPEN for this simulation? Those who know it, please give some advice: lol
Isn’t this three-phase? You can just create a three-phase diagram directly
Well, after adding the extractant aniline, it becomes a ternary system; but what I want is for the addition of the extractant to alter the relative volatility, and then, after removing the extractant, to create a binary gas-liquid equilibrium phase diagram, without any experimental data available
It’s actually very simple: go directly to Flash2, set a certain pressure, and consider different water inlet flows; under the condition that the total flow rate of propanone and methanol remains constant but the concentration varies, calculate the mass/mole fractions of methanol and propanone in the vapor phase and the liquid phase. Then calculate based on the definition of relative volatility.
