Critical fluid technology uses the powerful solvent properties of gases compressed to their critical point. Each substance has a unique critical point, defined by the temperature and pressure at which the liquid and vapor phases become identical. Critical fluids have a useful combination of liquid-like density and solvency, and gas-like viscosity, diffusivity, compressibility and lack of surface tension.
These fluids
rapidly penetrate substrates and dissolve a wide range of chemicals.
Furthermore, the critical region is characterized by an ability to
control solvent power with only minor changes in temperature and pressure.
Based on these properties, a number of practical, state-of-the-art
industrial processes have been developed.
CF Technologies is a leading developer of critical fluid processes, as well as
being the designer and manufacturer of the processing equipment.
