COSMO-SAC model
Thread Content
In Aspen, there is a model called COSMO-SAC. I’ve read in the literature that this model can use quantum chemical methods to predict gas-liquid equilibrium data. However, when I try to use it, Aspen indicates that parameters are missing due to the rarity of the substances involved. I don’t know where to enter these parameters, nor do I know if some basic physical properties are required. Does anyone understand this model? I need help!
Thanks for sharing; I’m a newcomer, so I’ll take the chance to learn a bit*
