Supercritical extraction plant and its industrial application

With the rapid development of science and technology, the modern applied technology of new chemical, biological and pharmaceutical industries has become the development direction of high-tech enterprises in these industries. Solvent Extraction, which is closely related to biological technology and pharmaceutical industry, is a very important part of the chemical industry, especially Supercritical Fluid Extraction (SFE) has become a priority development technology in petroleum chemical industry, biological pharmacy and food additive industries. Sfe.technology integration is the integration of chemical industry, machinery, instruments and other industries. The theoretical basis is the theory of supercritical co2 fluid phase equilibrium, which has been studied in the world and China for more than 20 years, and the mathematical model of supercritical co2 fluid extraction studied by the academic community. In recent 20 years, in order to make the application of supercritical co2 fluid extraction technology synchronous with the international technical level, domestic high-tech enterprises have gradually studied and applied a small scale and a certain degree of automation of supercritical co2 fluid extraction device. However, the current development situation is far behind the international leading level. Application in large scale, the industrialization of supercritical carbon dioxide fluid extraction device, solve the supercritical carbon dioxide fluid phase equilibrium theory and extraction plant related pressure balance, the control of fluid motion, the problems related to material loading continuous extraction is to improve the supercritical carbon dioxide fluid extraction (sfe) technology is an important part. The key technology of the large supercritical co2 fluid extraction device studied in this paper is to improve the technical level of the industrial supercritical co2 fluid extraction device in practical application, and to improve the theory of phase balance and the theory of extraction.
