Supercritical CO2 fluid extraction equipment is specifically designed for extracting desired compounds using supercritical carbon dioxide (CO2) as the solvent. This extraction method is widely utilized in industries such as pharmaceuticals, food and beverages, cosmetics, and natural product extraction. Supercritical CO2 fluid extraction equipment is available in various sizes and configurations, ranging from small-scale laboratory units to large-scale industrial systems. The selection of equipment depends on the specific extraction requirements, desired production capacity, and budget considerations.

SCFE Plant is a high pressure system equipment to realize the conversion of CO2 between gaseous, liquid and supercritical states to achieve substance extraction and separation. The SCFE plant controls the CO2 fluid to extract, separate and purify the material above the critical temperature (32℃) and pressure (7.38MPa).

Supercritical Fluid Technology Introduction

As an advanced and environment-friendly extraction and separation method, supercritical CO2 fluid extraction technology makes use of special dissolving property of supercritical CO2 fluid to extract, separate and refine target substance.

CO2 SFE Technology is now the most advanced green and environmentally friendly extraction & separation technology in the world. The fluid at the supercritical state can flow like liquid and penetrate and diffuse like gas. It has very strong solubility for the material. CO2 is the most widely used supercritical fluid medium.

Working Principle

Supercritical fluid(SF or SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can dissolve materials like a liquid, and effuse through solids like a gas. Characterized by large density, low viscosity, high diffusion coefficent, it boasts good solubility and transfer properties. (When it's close to the critical point, supercritical fluid's solubility is very sensitive to changes of pressure and temperature. By controlling pressure and temperature, operator could conveniently control its solubility, transfer and reaction abilities.).
