A review of the industrial applications and scale-up of the supercritical CO2 extraction process

Résumé

This review examined the importance of supercritical CO2 extraction and its industrial applications and scale-up. The need to have a sustainable development in order to tackle environmental concerns has led to the discovery of more efficient and safer alternatives to organic solvents. When a substance is pushed beyond its critical temperature and pressure, the distinction between the liquid and vapor phases vanishes, resulting in a homogenous fluid that possesses tunable physicochemical properties. Among the various candidates for supercritical applications, carbon dioxide (CO2) stands out as the premier choice. Supercritical carbon dioxide (scCO2) signifies the future fluid for next-generation power supply systems, operating above its critical point (31.1 °C, 73.0 bar) with its gas-like mass transfer and liquid-like density. The green-solvent properties of supercritical (scCO2) are highly dependent on its density, pressure and temperature. Its relatively mild critical parameters (31.1 °C and 73.0 bar), combined with its non-toxicity, non-flammability, and low cost, have made the application of supercritical carbon dioxide (scCO2) relevant in free radical polymerization. This unique behavior has revolutionized industries that previously relied on toxic organic solvents and energy-intensive thermal processes.
