Super Critical Fluid Extraction
With rich industrial experience, we have been engaged in offering solutions for the Super Critical Fluid Extraction (SCFE). It is due to the assistance of our advanced technology and skilled professionals, we undertake designing, engineering, erection, testing and commissioning of the plant in an effective manner.
- The process of separating one component (the extraction) from another (the matrix) using supercritical fluids as the extracting solvent
- Extraction is usually from a solid matrix, but can also be from liquids
SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product (e.g. decaffeination) or collect the desired product (e.g. essential oils)
Carbon dioxide (CO2) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol. Extraction conditions for supercritical CO2 are above the critical temperature of 31°C and critical pressure of 74 bars. The addition of modifiers may slightly alter this.
