Thermodynamics of Polymer Solution

02/16/2017 3:36 PM

Hi everybody, i need to do phase equilibrium calculation for polymer mixture. HPS is used to separate super-heated polymer(LLDPE) from gas diluent (isobutene). I think i need to use vapor-solid equilibrium for the mixture, however on the internet there are lots of materials which use vapor-liquid equilibrium for the mixture. which one should be used ?? can someone help ? Thanks in advance

Vapor-solid equilibrium like sublimation? Maybe CO2 has similar mechanics...

HPS = High Pressure Steam or what?

Need much more info. Concentrations, temperatures, and just exactly what you are trying to do.

Answering the question: "Why do you need to do phase equilibrium calculation?" would clarify things.

Be detailed in your answer!
