Thermodynamic Assessment of the Partitioning of Acetone between Supercritical CO₂ and Polystyrene Using the Polar PC-SAFT Equation of State.

ABSTRACT: Supercritical carbon dioxide (scCO₂) has gained considerable attention in the process industry due to its favorable economic, environmental, and technical characteristics. Polymer processing is one of the key industrial applications where scCO₂ plays an important role. In order to be able to efficiently design the polymer processing equipment, understanding the phase behavior and partition of solutes between scCO₂ and polymers is necessary. This paper investigates the partitioning of acetone - a conventional polar cosolvent - between scCO₂ and polystyrene - a glassy polymer. We highlight the importance of taking into account the polar interactions between acetone molecules and their role in the polymer phase behavior. The system is modeled under
