Differences between subcritical and supercritical process

1.The extraction medium is different. Supercritical extraction with carbon dioxide CO2, subcritical extraction mainly with five solvents: butane, propane, DME, R134a and liqufied ammonia.

2.The pressure is different. Supercritical extraction pressure in 20-50MPa, subcritical 0.3-0.5MPa.

3.Temperature: supercritical extraction above 40 degree centigrade, subcritical is room temperature or lower temperature.

4.Subcritical extraction with smaller investment, lower production costs, larger scale.
