Extraction of corn germ oil with supercritical CO2 and

Abstract. The aim of this work was to investigate corn germ oil extraction using supercritical CO 2 and cosolvents addition (hexane, acetone and ethanol). The effects of temperature (45–85 °C) and pressure (15–25 MPa) on the extract yield were evaluated for the tests conducted only with supercritical CO 2.The addition of cosolvents to supercritical CO 2 was also examined at 25 MPa

Batch and continuous solvent extraction SpringerLink

Two physical processes are used for the removal of oil from oilseeds, one called “solution extraction” and the other “diffusion extraction.” In batch type solvent extraction plants, a diffusion process takes place. Due to their high steam and labor requirements, such plants are being steadily replaced with continuous solvent extraction plants, whose main component is the extractor
