M
odeling of the phase behavior of polymer solutions is a crucial requirement to develop new polymer solution technologies and
to design various polymer processes, such as purification, fractionation, devolatilization and polymer production. In particular,
the Liquid-Liquid Equilibrium (LLE) calculation is essential for processes design of polymerization. The hydrogen bonding in
polymer solutions leads to deviate remarkably from normal solutions behaviors and is a major cause of different phase behaviors. The
perturbed-chain statistical association Fluid Theory (PC-SAFT) Equation of State (EoS) is applied to calculate the pressure-volume-
temperature (PVT), infinite dilution weight fraction activity coefficient (WFAC), Vapor-Liquid Equilibrium (VLE) and Liquid-Liquid
Equilibrium (LLE) of associating polymer mixtures with hydrogen bonding association such as self- and cross-association with
various phase behaviors such as Upper Critical Solution Temperature (UCST), the Lower Critical Solution Temperature (LCST) and
closed-loop of polymer solutions. The PC-SAFT model shows a satisfactory performance.
Biography
Bong-Seop Lee has his expertise in modeling the phase behaviors on organic molecules, polymers, biological molecules (i.e., amino acid, peptide) and electrolyte
solutions (i.e., inorganic salt, ionic liquids). He has received his Master’s degree and developed the electrolyte-PC-SAFT equation of state by combining PC-SAFT
and primitive mean spherical approximation in his PhD course. In his Post-doctoral studies, he focused on the modeling of physical and chemical properties of
ionic liquid mixtures. His research interest is in dissociation phenomena of weak and strong acids and the equilibrium of various materials (polymer, blend, organic
solvent) at high pressure condition.
