Hysys物流里面的untility里面有一个co2 freeze out的功 ...？ 帮助文档的说明。楼主可以参考。 about the co2 freeze out analysis an equation-of-state based approach is used to calculate the incipient solid formation point for mixtures containing carbon dioxide (co2) and several other components. the model can be used for predicting the initial solid formation point (temperature) in equilibrium with either a vapor, liquid, or (in a rare situation) an aqueous phase that exists at the stream conditions. the fugacity of the resulting pure solid is obtained from the known enthalpy of fusion, triple point temperature and heat capacity difference between liquid and solid. the fugacity of the corresponding fluid phase (in equilibrium with the solid) is calculated from the equation of state. co2 solids prediction is restricted to the peng robinson (pr) and soave redlich kwong (srk) equations of state. 查看更多
