The CO2 raw gas flows to the CO2 compression package consisting of a CO2 piston or screw compressor. The compressed gas is then sent to the drying and purification system to remove the moisture and the impurities inside the gas. After this high-pressure treatment unit, a closedcircuit refrigeration system is used to cool the CO2 gas to its liquefaction temperature.

The liquid CO2 created in the condenser is gravity-fed to the stripper and reboiler, where the non-condensable impurities are reduced to final product high-quality CO2 including to food- and beverage-grade specifications.

The liquid CO2 product is then transferred to liquid storage for further use or pumped through a heat exchanger and sent to a sequestration site as a gas under pressure.
