Physical property selection
Thread Content
When using Aspen to simulate the separation of water and dimethyl sulfoxide, what property method should be chosen? I selected NRTL, but the minimum reflux ratio obtained from the simulation was 0.015, which seems too low. I’m wondering if anyone has carried out this type of separation before; I would like to ask what property method would be appropriate in this case Thank you

You think that if it’s small, other conditions can be tightened.
