Aspen partially miscible systems, binary interaction parameter problem
Thread Content
Since the binary interaction parameters for three-phase azeotropic systems in the textbooks indicate that those from the LLE database should be used, then why not consider VLE gas-liquid equilibrium? Also, it’s not possible to select both VLE and LLE at the same time; it is stated that one has already been specified. Does that mean that only LLE needs to be considered for layering?
Choose the appropriate binary interaction parameter by considering temperature, pressure, and phase.
It is best to consider VLLE; for cases with only two phases, LLE can be considered. It is definitely incorrect to consider only VLE in such situations.
