Solubility model of palm oil extraction from palm fruit using sub-critical R134a

The exploration of alternative solvents for supercritical fluid extraction (SFE) technology has been attributed to the high capital investment due to higher pressure required by using supercritical carbon dioxide (SC-CO2) as a solvent. One of the potential alternative solvent is the sub-critical R13...
