Pilot units for supercritical fluid extraction of solids

Selective separation of valuable thermolabile components from solid and liquid raw materials using a supercritical gas as solvent.


Low-temperature separation produces natural extracts Chemically inert and non-toxic solvents leave no residue in the extract Solubility variation achieved by changing extraction pressure and temperature High selectivity and diffusion rate


Closed CO2 cycle Contaminant-free recirculation of supercritical solvent High-performance separation step Hand-operated quick-opening closures Continuous process with liquid raw materials


Fractionated separation with fluid cyclone Fractionated extraction n Modifier system Multivessel design Preparation for retrofit with additional extractors, separators, etc. Data acquisition system Process control and batch documentation with programmable logic controller (PLC)
