The Co-solvent Enhancement calculation is a fundamental procedure in Supercritical Fluid Extraction used to estimate the solubility increase of a target solute when a polar entrainer is added to a supercritical carbon dioxide stream. This method allows process engineers to determine optimal solvent formulations and extraction efficiencies without requiring complex equation-of-state modeling. It is particularly useful during the preliminary scoping phase of solvent design for polar or high-molecular-weight compounds.
