Pilot Plant SFC Systems

Going green has never been so easy

From the food industry to aerogels and polymers and many other industries inbetween, Applied Separations is meeting the growing, world-wide commitment to a cleaner, greener environment.

Environmentally friendly Supercritical Fluid (SCF) technology works with today's innovative, easy-to-use systems.

Unique benefits of supercritical fluid extraction systems


  • Cleaner extraction process with supercritical CO2 compared to conventional extraction solvents
  • No petroleum based solvents required
  • No toxic solvent residues remain in the product, due to the volatility of supercritical CO2
  • No health hazards due to elimination of hazardous and toxic solvents
  • Extracts have longer shelf-life and better blending characteristics due to co-extraction of antioxidants and lipids.
  • CO2 is Safe, inexpensive and readily available
  • CO2 is an ideal substitute for many hazardous and toxic solvents
  • CO2 has good mass transfer, due to the low viscosity of the solvent
  • Supercritical CO2 is a selective solvent based upon its variable density (e.g. extraction of caffeine from green coffee without removal of flavour precursors)
  • Offers solubility without surface tension, supercritical CO2 has the properties of both a liquid and a gas, making even the most sensitive of processes possible
  • CO2 has a low overall energy expenditure
  • Only existing CO2 is used, not produced, in the SCF process
  • NO addition to any greenhouse effect

What is supercritical CO2?


  • Carbon dioxide is in its supercritical fluid state when both the temperature and pressure equal or exceed the critical point of 31°C and 73 atm (see diagram).


  • In its supercritical state, CO2 has both gas-like and liquid-like qualities, and it is this dual characteristic of supercritical fluids that provides the ideal conditions for extracting compounds with a high degree of recovery in a short period of time.


  • By controlling or regulating pressure and temperature, the density, or solvent strength, of supercritical fluids can be altered to simulate organic solvents ranging from chloroform to methylene chloride to hexane.


  • This dissolving power can be applied to purify, extract, fractionate, infuse, and recrystallize a wide array of materials.

PILOT PLANT SUPERCRITICAL FLUID EXTRACTION SYSTEMS

Pilot Plants


Applied Separations offers SCF systems in any size and configuration. Although the size of a pilot system versus a production system is arbitrary, customarily, Applied Separations designates pilot systems as having extraction/reaction vessels from 5 litres to 80 litres. Greater than 80 litres, are considered production scale.


Applied Separations work with you one-on-one to design your custom, multipurpose, movable pilot plant/small production system. The system may be as straight forward as a manual system having one extractor vessel and venting to atmosphere to an automated system having multiple extraction/reaction vessels with multiple separators, recycling the CO2.
