超临界流体技术
Supercritical fluid equipments and high pressure equipmentss enable the development of sustainable and environment-friendly processes and products.
Application
Supercritical processing is widespread across industies including natural products, bio- and advanced-materials, textile manufacturing and others.
 
The most well-known example is the extraction of caffeine from coffee beans using supercritical CO2, which has been used commercially for many years at a large scale. Today supercritical fluids are efficiently used and developed by SEPATEK for many applications:
 Food & Nutraceuticals
 Perfumes & Cosmetics
 Pharmaceuticals
 Textiles
 Electronics
 Aerogels, Ceramic and innovative Materials
 Waste treatment & Waste valorisation
 Oil & Gas industries
 
What is a Supercritical Fluid?
CO2 is the most commonly used supercritical solvent. Produced in excess by industry at high purity, it is inexpensive, non-toxic, non-flammable and has a near ambient critical temperature (31°C). Critical pressure is reached at 74bar.
 
 
A fluid is in “supercritical state” when placed at a temperature above its critical temperature and at a pressure above its critical pressure. Small changes in temperature or pressure can result in drastic changes in fluid density, solvent power and other physical properties.
 
Supercritical fluids exhibit excellent transport properties: low viscosity, high heat and many diffusivities.
