The fuel is burned under carefully controlled conditions. After water/soda ash scrubbing, CO2 from the flue gas is
absorbed into a monoethanolamine based solution which is subsequently heated by the combustion process to release
the raw CO2 gas. The CO2 is then led to a vertical, two stage, dry running (oil free) compressor and on to the
high pressure, potassium permanganate purifier. After thorough drying in an automatic twin tower molecular sieve
drier, the CO2 receives final purification in an activated carbon filter prior to feeding into an R404a refrigeration loop
in the liquefier. The pure, liquefied CO2 can then be fed to a bulk CO2 storage tank.
This continuous process is efficient, reliable and safe. The CO2 meets international food-grade quality standards
and is used daily by the world‘s top gas companies, soft drink and beer brands in over 100 countries.
