Characteristics of Supercritical carbon dioxide extraction process

Characteristics of Supercritical carbon dioxide extraction process

In the supercritical state, Supercritical carbon dioxide contacts with the substance to be separated, so that components with different polarity, boiling point and molecular weight can be selectively extracted in turn. Of course, the extract corresponding to each pressure range cannot be single, but the conditions can be controlled to obtain a reasonable proportion of mixed components, and then the supercritical fluid can be turned into ordinary gas by decompression and temperature rise, so that the extract can be completely or basically precipitated, so as to achieve the purpose of separation and purification. Therefore, the Supercritical carbon dioxide extraction process is a combination of extraction and separation.

What are the characteristics and applications of Supercritical carbon dioxide generation?

What are the characteristics and applications of Supercritical carbon dioxide generation?

The physical characteristics and heat transfer laws of Supercritical carbon dioxide are complex and need systematic research. Supercritical fluid will deviate from Ideal gas in the process of thermodynamic change, which is different from conventional liquid or gas. Especially in the near critical region and across critical point, its thermodynamic parameters will change nonlinearly. The uniqueness of fluid flow and heat transfer laws caused by its unique physical properties will make it more difficult for the system to operate under variable operating conditions and control load regulation. Therefore, to master the physical properties and heat transfer laws of ultra Supercritical carbon dioxide in many ways, a large number of experimental data are needed as technical support.
