Supercritical Fluid Processing
Supercritical CO₂ extraction, aerogel drying, particle formation and solvent-free processing under mild conditions for heat-sensitive and porous materials.
In short
Supercritical CO₂ extraction, aerogel drying, particle formation and solvent-free processing under mild conditions for heat-sensitive and porous materials. Supercritical fluid processing is carried out on an Arşen TSG-M070 system using supercritical carbon dioxide (scCO₂). Above its critical point (31 °C, 7.
Supercritical fluid processing is carried out on an Arşen TSG-M070 system using supercritical carbon dioxide (scCO₂). Above its critical point (31 °C, 7.4 MPa), CO₂ combines liquid-like solvating power with gas-like diffusivity; selectivity is tuned by pressure and temperature, and depressurisation leaves no residue. Typical applications include extraction of essential oils and bioactives from botanical products, conversion of silica and polymer gels into aerogels without shrinkage (supercritical drying), micro/nanoparticle formation by RESS and SAS routes, and solvent-free cleaning or impregnation of porous materials. The service answers questions on extraction yield and selectivity, aerogel pore structure, particle size and morphology, and process validation before scale-up. It serves food, nutraceutical, pharmaceutical, cosmetic, advanced materials and energy organisations.
What you receive
Processed product (extract, aerogel, particles or cleaned material) in labelled packaging
Process record covering pressure, temperature, CO₂ flow rate, duration and co-solvent ratio where used
Extraction yield or mass balance calculation
Product characterisation by BET, particle size or SEM on request
Process summary report (PDF)
How it works
Request and scoping
Application type (extraction, drying, particle formation), feedstock properties, target product and quantity are agreed; a pressure–temperature window is proposed.
Sample reception and preparation
The feedstock is logged, ground, dried or solvent-exchanged where needed, and loaded into the extraction vessel.
Measurement
The system is brought to the specified pressure and temperature; the process is run under controlled CO₂ flow and time, and the product is collected in the separator.
Reporting
The product is weighed and delivered with the process record; yield, selectivity and product properties are discussed with you on request.
