HPE 150

The Pilot Scale High-Pressure Extraction Unit is designed for process studies and small productions.  The solid material is placed inside the  extractor. The extractor contains a fluid heating jacket. The solvent (e.g. CO₂) is pressurized using a high pressure membrane pump.  The extraction pressure is regulated  automatically. Downstream of the expansion valve the extract is precipitated in a separator at decreased pressure and the recycled solvent is passed to the pump inlet after being condensed by a chilling unit for pumping to  extraction conditions and closing the solvent loop. The extract is collected at the bottom of the separator.
