Overview

Supercritical fluid extraction is an emerging subject in modern chemical separation, and it is a new separation technology in the world.The so-called supercritical fluid refers to the thermodynamic state of the fluid above the critical point (Pc, Tc),the critical point is the gas-liquid interface has just disappeared state point.The supercritical fluid has very unique physical and chemical properties.Its density is close to the liquid,the viscosity is close to the gas,and the diffusivity is large,the viscosity is small,and the dielectric constant is big,so the separation effect is good and it is a great solvent.Supercritical extraction,in which the solvent is in contact with the extract in the extraction cylinder at high pressure and suitable temperature,then the solute diffuses into the solvent,next,change the operating conditions in the separator to precipitate a dissolved substance to achieve separation.The equipment is widely used in biological,pharmaceutical,food and other fields.
