I am working on salt-assisted extraction distillation to separate the DMC-MeOH (dimethyl carbonate-methanol) azeotrope system, and the problem is that there are no parameters related to salt; I don’t know how to set them. At the same time, there are also no gas-liquid equilibrium data for DMC-MeOH-extractor-salt. Limited resources prevent conducting experiments. So the entire simulation gets stuck here and cannot run. I can’t understand the questions below; please help, expert. Thank you!
