Through a series of purification treatment such as desulfurization, decarbonization and dehydration of biogas, clean and pollution-free natural gas can be produced, which greatly increases the calorific value of combustion.The off-gas from decarbonization can also produce liquid carbon dioxide, which can make full and effective use of biogas without secondary pollution.According to the requirement of the final target product, the Company technology can be used to produce natural gas from biogas, which can be directly transferred to the natural gas pipeline network as civil gas; or CNG (compressed natural gas for vehicles) can be produced by compressing natural gas to 20-25MPa as vehicle fuel; or LNG can be produced by Deep-cold liquefaction of the product gas.
