Applying Supercritical CO2 to green manufacturing in the gas separation, food, and pharmaceutical sectors
Supercritical carbon dioxide (scCO2) is an efficient tool in materials design due to its favorable thermodynamic and transport properties, such as high density and diffusivity, low viscosity, and the absence of surface tension. It can be used as a solvent, transport medium, plasticizer, foaming agent, or a reaction medium. In addition, scCO2 usage allows for reducing or eliminating effluents and solid wastes, making it a valuable tool in green manufacturing. The lecture will comprise three parts. In the first part, the properties of supercritical state will be highlighted and the most important applications of scCO2 will be introduced. Thereafter, the enhancement of the properties of composite membranes aimed at gas separation and food packaging by filler modification in scCO2 will be presented. The last part of the lecture will be devoted to applying supercritical fluid technology and cocrystal engineering to design systems for the controlled release of active substances and drug bioavailability enhancement.
