ESL's Supercritical Technology
ESL
employs the latest Supercritical CO2 methods and
equipment to capture the finest natural extracts.
What is CO2?
CO2 is an atmospheric gas composed of
one carbon and 2 oxygen atoms.
In 2004, CO2 in the earth’s atmosphere = 379ppm
or 0.038% by volume.
It is a non-flammable, colourless, odourless natural constituent
of air and once pressurised is an ideal and gentle, natural
solvent.
What is Supercritical CO2?
At conditions above its critical temperature and pressure,
CO2 exhibits the propensity
to dissolve materials. "This critical point is reached
at pressures above 73 atmospheres and temperatures over 31°C,
and by varying temperature and pressure above these limits
supercritical CO2 can be used to selectively extract
components from raw materials."
