Liquid-liquid extraction
I'm simulating a liquid-liquid extraction using a mixture of water and acetone as a feed stream and a solvent stream containing methyl isobutyl ketone. When I run the simulation I get the error message: Feed: phase equilibria calculation error. (T = 298.15 K, P = 101.325,00 Pa, MoleFracs = { 0,6, 0,4, 0, }). The data is from a sample file available on DWSIM.

The issue has been reported to the developer. It will be fixed soon.


The issue is now fixed with the latest version of DWSIM. Please download the latest version of DWSIM and try running the simulation.
