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