The process flow of carbon dioxide production device varies depending on the specific technology and equipment used. However, the general process flow for producing carbon dioxide (CO2) from various sources, such as fermentation or combustion processes, typically involves the following steps:

Source gas collection

The source gas containing CO2 is collected from the process or combustion exhaust, or from a fermentation process.


The collected source gas is purified by removing impurities such as water, sulfur dioxide, and other contaminants that could interfere with the production process.


The purified CO2 gas is compressed to a higher pressure to facilitate the subsequent processing steps.


The compressed CO2 gas is cooled to a very low temperature, which causes the gas to condense into a liquid.
