Supercritical Extraction Plant

All activities of the firm are related to supercritical extraction (SCE) by carbon dioxide.

Principles of CO₂ Extraction (SCE)

Extraction by supercritical carbon dioxide is an advanced separation process meeting the strictest ecological and hygienic requirements. Compressed gas passes in an extractor through a bed of extracted material. The gas laden with extract is then fed to a separator via an expansion valve. By reducing the pressure in the expansion valve the solvent power of carbon dioxide is also reduced and the extract precipitates in the separator. The gaseous extract-free carbon dioxide is then liquified in an condenser, compressed in an circulating pump, heated and fed back to the extractor. This completes the process that operates in a closed circuit consisting of intakecompression-extraction-expansion-condensation-intake. All process side parts are made of stainless steel.
