Good morning everyone,

I am trying to simulate the dissolution and re-precipitation process of EPS on Aspen Plus, but I have some difficulties to correctly define the polymer characteristics in order to get solid streams. As a matter of fact, all EPS streams that I try to define result being in the liquid phase, even at low temperatures. I think that this is due to the fact that the software cannot predict the melting temperature of the polymer, but I don’t know how to implement it since I already gave Aspen Plus the Van Krevelen structure of all the molecules involved, but it does not work.

Does someone know if Aspen Plus is able to predict the polymers behavior also in the solid phase? In case, which inputs should be given to the software?

Thanks in advance,

AP
