Supercritical CO2 fluid extraction technology is a new type of separation technology in modern chemical separations, with the characteristics of fast mass transfer rate, strong penetration ability, high extraction efficiency and low operating temperature. This technology has been widely used in the pharmaceutical, food, chemical and other industries.
SFE is a typical operation at high solvent feed ratio, high air velocity and low fluid viscosity. Compared with traditional liquid-liquid extraction, SFE-CO2 has better selectivity, and supercritical fluid extraction technology has broad application prospects in the food, chemical and pharmaceutical industries.
The extraction kettle is one of the keys to the development of supercritical extraction technology. It has the characteristics of high strength, strong rigidity, good stability and durability, and good quick-opening sealing effect. Therefore, the design of supercritical extraction kettle should be strictly carried out according to the process requirements.
