Modeling supercritical mixtures: how predictive is it?

Abstract

In the last decade, major advances have been made in modeling solubilities and phase behavior in supercritical fluid (SCF) mixtures. It is possible to predict the solubility of a solid in pure and mixed SCFs semiquantitatively with perturbed hard-sphere equations of state, but it is necessary to know the vapor pressure. For liquid-fluid and multiphase systems, cubic equations of state and lattice models have been used to correlate complex phase behavior, but enormous challenges remain to make these models predictive.The advancements in research in supercritical fluid (SCF) technology have been the subject of several recent reviews (

Molecular thermodynamics of solute‐polymer‐supercritical fluid systems

“…The Peng-Robinson equation of state, with quadratic mixing rules for both the size and attractive parameters, is used to calculate c&, based on a large number of investigations reviewed elsewhere (Brennecke and Eckert, 1989;Johnston et al, 1989b …”

Supercritical CO2‐cosolvent extraction of contaminated soils and sediments

“…Supercritical fluid (SCF) extraction has received much attention as a technique for separating relatively nonvolatile materials (Paulaitis et d., [33]; Ely and Baker, [13] [4]; Johnston et aZ., [19]). Typically in SCF extraction a solvent gas such as carbon dioxide, at high pressure and moderate temperature, is contacted with a solid or liquid phase.…”

Reliable Computation of High-Pressure Solid−Fluid Equilibrium

“…1,6,7 Even the simple van der Waals equation can, at least qualitatively, describe most of the types of binary fluid behavior, as classified by von Konynenburg and Scott. 8 Probably the two most popular models are the PengRobinson equation 9 and the Soave-Redlich-Kwong equation.…”
