Supercritical extraction systems

Extraction with a supercritical fluid, usually CO2, instead of hexane or steam distillation — over 150 industrial plants worldwide, with CO2 recognised as a safe solvent by the FDA and EFSA.

1 · What it gives

Supercritical fluid extraction separates components by their different solubility in a supercritical fluid, in three stages: dissolution, sweeping of the analytes and trapping. It is a superior alternative to conventional solvent extraction (hexane, hydrofluorocarbons) and steam distillation, which are increasingly restricted. There are more than 150 plants worldwide with a total extraction vessel volume above 0.5 m³.

2 · What it replaces 6

D1Process equipment for residue-to-product plants — anaerobic digesters and biogas upgrading, composting turners and granulation lines, biomass pelleting, pyrolysis and carbonization kilns — instead of incinerators, landfill, open lagoons and open burning
Replaces: Landfill and open dumping of organic waste; open burning of crop residues; open anaerobic lagoons; incineration of wet organic waste
EAC
D1Bio-based binders and bio-solvents instead of petrochemical resins and VOC solvent systems in paints and coatings
Replaces: Petro-derived alkyd/acrylic binders; volatile organic solvent systems (white spirit, toluene, xylene) in solvent-borne paints; part of …
CHEM
D1Biosurfactants (rhamnolipids, sophorolipids) instead of petrochemical surfactants in cleaning and industrial formulation
Replaces: Petrochemical surfactants in cleaners and formulations - linear alkylbenzene sulfonate (LAS), alcohol ethoxylates (AEO), alkylphenol …
CHEM
D3Odour, H₂S, ammonia and VOC emissions treated by biofilters, biotrickling filters and bioscrubbers instead of chemical scrubbers (caustic/hypochlorite/acid) and thermal oxidizers
Replaces: Chemical scrubbers dosing sodium hydroxide, sodium hypochlorite and sulfuric acid; regenerative/thermal oxidizers burning gas to destroy …
EAC
D3Citric acid by Aspergillus niger fermentation instead of extraction from citrus fruit
Replaces: Citric acid extracted from lemons, limes and other citrus (calcium citrate route, Italy and California before 1930)
FOOD
D1Fermentation (stainless and single-use bioreactors, solid-state reactors) and downstream equipment (centrifuges, filtration, spray and fluid-bed drying, formulation) for local production of enzymes, microbial products and fermentation ingredients instead of chemical-synthesis plants and imports
Replaces: Chemical-synthesis routes and imports for the products in FI-, FD-, I- and A-series articles (enzymes, organic acids, vitamins, microbial …
