✦ Synopsis

Entrainers have the potential of enhancing the solubility of a solute in a supercritical gas. Removing the entrainer from the supercritical gas, on the other hand, reduces the solubility. This effect may be used for separating solutes from a supercritical solvent. It will be shown, for example, that for the system CO2 and ethanol, it is advantageous to extract the ethanol in a countercurrent extraction with water, leading to a reduction in the solvent power of the gaseous phase. This was tested using a deodorizer condensate of soybean oil containing more than 55 wt % tocochromanols.

Models are developed for isothermal desorption in a fixed bed of adsorbent particles. While more general models require numerical solution of the governing equations, two practically important cases have analytical solutions: 1) an equilibrium desorption model where the rate of desorption is control

## Abstract One of the phenomenological observations in any supercritical system is the common pressure where all the solubility isotherms intersect. Thus, this crossover pressure addresses a thermodynamic constraint or a key set of conditions for supercritical mixtures. In this paper, a phase stab
