The system compresses, purifies, dehumidifies, and liquefies the CO
2. When the CO
2 gas is ejected to the atmosphere, the liquid CO
2 is re-used within the system to save energy. This results in a cost-efficient separation of CH
4 and CO
2. When the CO
2 is sold as liquid CO
2, an extra cooling unit and a liquid CO
2 storage tank is required.
The CO2 installation can be used in the beverage industry, greenhouses and food freezing applications.
