When using extract for extraction simulation, why aren’t the substances separated?
Thread Content
An extraction simulation was carried out using Aspen’s extract function to simulate the extraction of caprolactam from hydrated ammonium sulfate by benzene. Under normal circumstances, benzene and caprolactam should flow out at the top of the tower, while hydrated ammonium sulfate flows out at the bottom. However, the simulation results showed that ammonium sulfate, caprolactam, and benzene all flowed out at the top of the tower, with only water flowing out at the bottom. I don’t know where the mistake is Seeking advice!
I guess a binary interaction wasn’t included~:)

It’s very likely due to liuzx520; it is recommended to check that. Also, is benzene’s solvating power for caprolactam that strong?
