The liquid-liquid equilibrium (LLE) calculation for polymer solutions is essential for processes design of polymerization. The hydrogen bonding in polymer solutions leads to deviate remarkably from normal solutions behaviors. For the rational design of polymer process, the reasonable model is required, and the PC-SAFT equation of state (EoS) in many models has been widely applied to calculate the LLE of polymer solution. In this work, PC-SAFT EoS is extended to calculate the various phase behaviors of polymer fluids such as upper critical solution temperature (UCST), lower critical solution temperature (LCST) and closed-loop with both UCST and LCST. The calculated results with PC-SAFT EoS shows a satisfactory performances. |
