Design of a Cost‐Reduced Flexible Plant for Supercritical Fluid‐Assisted Applications

Abstract

A novel batch plant for supercritical CO 2 applications is proposed which is not equipped with expensive components, such as high-pressure pumps, making it particularly suitable for bench-scale use. For the first time, the use of a hanging scale is suggested to weigh the amount of CO 2 required for the experiment and the use of the thermodynamics to reach the working conditions. The rig is able to cover different applications, e.g., aerogel drying, impregnation, and extraction, showing high flexibility. An approximate cost analysis has been performed considering as a reference a 150-mL vessel. It has been calculated that both the setup and running costs are considerably lower than the common batch and semicontinuous rigs.

Determination of Coenzyme Q10 Content in Food By-Products and Waste by High-Performance Liquid Chromatography Coupled with Diode Array Detection

“…Hence, more CoQ10 can be recovered from a food matrix by extracting its oil. However, supercritical fluid technology is expensive due to the high investment costs [ 38 ]. Oil extraction using a green solvent followed by solvent evaporation could be, thus, a less expensive alternative.…”

Recent Advances in Supercritical CO2 Extraction of Pigments, Lipids and Bioactive Compounds from Microalgae

“…Furthermore, the selectivity of SFE can be easily tuned by changing the extraction conditions, i.e., pressure and temperature, or by using a co-solvent [ 1 , 16 , 17 ]. However, its main drawback is the high equipment cost, mainly due to the high extraction pressure [ 18 ]. SFE of microalgae is frequently studied as a consequence of the variety of components that can be recovered [ 9 ].…”
