Modeling of Fluid Phase Equilibria by PC-Saft EOS: Solubility of Gases/Vapor in Polythylene

Mahapatra, Dibya Lochan (2009) Modeling of Fluid Phase Equilibria by PC-Saft EOS: Solubility of Gases/Vapor in Polythylene. BTech thesis.



The prediction or correlation of thermodynamic properties and phase equilibria with equations of state remains an important goal in chemical and related industries. Although the use of equations of state has for a long time has been restricted to systems of simple fluids, there is an increasing demand for models that are also suitable for complex and macromolecular compounds. Due to its ability to describe the thermodynamics of symmetric as well as asymmetric systems, the most common approaches for modeling gas-polymer solubility have been based on the PC-SAFT EOS. It has wide applicability starting from low molecular weight organic compounds to highly non-ideal macro-molecular weight system such as polymer In the present work, PC-SAFT equation of state of Gross & Sadowski, 2001 has been used to model solubility of various gases /vapors in liquid polyethylene to demonstrate the suitability of PC-SAFT EOS for polymer-solvent system.
