Blog about supercritical fluid systems.

The basic principle of supercritical fluid extraction is to dissolve the required chemical components with a supercritical fluid under conditions above the critical temperature and critical pressure, and then reduce the pressure of the fluid solution or increase the temperature of the fluid solution, so that the solute dissolved in the supercritical fluid precipitates due to its reduced density and reduced solubility, thereby achieving the extraction of specific solutes.

The supercritical CO2 extraction device can be used for high-pressure and suitable temperature extraction materials (solids and liquids) under the condition of separator replacement, so that the soluble materials can decompose the target products during the extraction and separation process.

Supercritical CO2 fluid extraction technology is a new separation technology in modern chemical separation. It has the characteristics of fast mass transfer rate, strong penetration ability, high extraction efficiency and low operating temperature. This technology has been widely used in medicine, food, chemical industry and other industries.

Supercritical CO2 fluid extraction kettle generally works under a high pressure of 32Mpa (sometimes higher), and needs to be disassembled frequently.

In recent years, with the gradual launch of various natural concept cosmetics, the consumer demand for personal care products containing natural ingredients has continued to grow, and plant extracts have become increasingly important in cosmetics, which also requires various plant extracts to be further optimized in terms of safety and efficacy. Supercritical CO2 extraction Process can not only complete deacidification,… Read More »Application of supercritical CO2 extraction Process in plant extracts

Supercritical CO2 extractor can obtain useful components to the maximum extent, and can selectively extract and separate.

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. With the development of industrialized SFE devices, the reliability, safety, rationality of operation and sufficient convenience of SFE devices will be more effectively guaranteed.
