INTRODUCTION Supercritical Fluid Extraction (SFE) is a eco-friendly alternative of extraction replacing organic solvents. In SFE use of Supercritical fluids (SCF’s) like supercritical CO2 as solvent is there. SCF are increasingly replacing organic solvents because of 2. Fundamentals of Supercritical Fluid Extraction Supercritical fluid extraction is based on the use of a fluid at pressures and temperatures beyond its critical point, in order to achieve significant physical changes that will modify its capabilities as solvent.

3 depicts the basic elements of a Extraction Modes.

In the supercritical fluid extraction (SCFE) process, extraction is carried out by a solvent above its critical pressure and temperature. A brief description of the SCFE process is given below. The commercial scale SCFE plant has three extractors, two separators, one CO2 hold-up tank and heat exchangers (see enclosed flow diagram). Supercritical fluids can be applied for biomass valorization both as a pretreatment technique or as a reactive extraction procedure to yield value-added coproducts.

The discovery of supercritical fluids led to novel analytical applications in the fields of chromatography and extraction known as supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE). Supercritical fluid chromatography is accepted as a column chromatography methods along with gas chromatography (GC) and high-performance liquid chromatography (HPLC).

· Supercritical Fluid Extractor · Large Essential Oil Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids. 5.3 Supercritical fluid extraction (SFE) SFE method is an extraction technique using fluids in conditions that are elevated above their critical point of temperature. The supercritical fluid density is similar to liquids, whereas its viscosity is comparable to the gas.
