using supercritical carbon dioxide and compressed propane as solvents. The extractions
were performed in a laboratory scale unit in a temperature and pressure range of 313–333K
and 19–25MPa for carbon dioxide and 303–333K and 8–12MPa for propane extractions,
respectively. A 22 factorial experimental design with three replicates of the central point was
adopted to organize the data collection for both solvents. The results indicated that solvent …
