Supercritical Extraction (SFE) and Micronization Pilot Systems
Process development at laboratory and pilot scale with supercritical fluids.
In supercritical fluid technology, usually with supercritical CO₂, pressure and temperature are used to tune the solvent properties. Extraction (SFE), micronization and spray drying (RESS/GAS) and continuous-flow reactions (SFC) are developed at laboratory and pilot scale before scale-up.
Typical process routes
- 1
Extraction of solids (SFE)
Active or valuable components are extracted from solid material with a supercritical solvent.
- 2
Multi-purpose SFE
A single pilot unit configured for several extraction tasks and materials.
- 3
Micronization and spray drying (RESS/GAS)
RESS is the rapid expansion of supercritical solutions and GAS the gas anti-solvent process; both are used to form fine particles.
- 4
Continuous reactions (SFC)
Reactions in supercritical fluids under continuous flow.
- 5
Phase equilibria
Apparatus for measuring phase behaviour under high pressure, the basis for process design.

Frequently asked questions
What is supercritical fluid extraction (SFE)?
SFE uses a fluid above its critical pressure and temperature, most often CO₂, as a solvent. Pressure and temperature adjust the solvent power, so components can be extracted selectively.
What do RESS and GAS mean?
RESS stands for Rapid Expansion of Supercritical Solutions, GAS for Gas Anti-Solvent. Both are routes to micronized particles used in micronization and spray drying.
