Abstract
The solubility behavior of solid and fluid components with supercritic al fluids (SCF) is investigated using a mean field equation of state. When densities, instead of the more commonly used mole fraction and pr essure, are used to illustrate solubilities, the effect of the solute' s vapor pressure becomes clear. An expression for the relation between the solubility and the second cross virial coefficient is derived. Th e effects of size and interaction energy are investigated by changing the solute and solvent parameters.
