Working principle：
After the mixed air containing carbon dioxide (CO2) enters the pressure swing adsorption (PSA) device adsorption tower, the adsorption capacity of the adsorbent in the adsorption bed is different with the change of pressure. CO2 in the raw gas is absorbed under pressure, and the components that are not easy to be absorbed are removed from the outlet of the adsorption bed. When decompression occurs, the adsorbed CO2 and residual impurities are desorbed and desorbed. The concentrated CO2 is refined, and one part returns to the PSA system and the other part is canned in the form of liquid products。Feed gas：
Fermentation gas、Conversion gas、Decarburization and regeneration gasMine GasOther mixed gases containing CO2Control mode and characteristics：
Service：
Provide patents and proprietary technology, provide the design for complete equipmentprovide general contracting of equipmentProvide technical service and personnel training during installation and commissioning of the equipmentAfter acceptance, the warranty period for one yearLong-term provision of spare parts, spare partsCO2 Purity: 99~99.999%（v），According to user's different usage and request production。
The quality of CO2 products meets national food grade CO2 standards
Note: CO2 recovery rate is related to raw material composition, pressure and CO2 purity。
