Extraction, cleaning, impregnation using supercritical fluids

Supercritical fluids can replace conventional solvents such as methanol, ethanol, methylene chloride, etc. Since some of these solvents are toxic, efforts are now being made to avoid their use.

Extraction of natural substances

The supercritical extraction of spices and herbs plays a major role in obtaining high quality products from natural raw materials.

Particle formation - Hygienic design

Numerous processes with supercritical CO2 have been developed which allow the generation or modification of fine particles with defined particle size distributions in micro- and even nano-scale of certain shape and/or determined morphology.

Shaped materials - Aerogels

The treatment of shaped solid materials with supercritical CO2 (scCO2) has moved in the area of interest during the last few years.
