Industrial gas streams such as natural gas, landfill gas, biogas, blast furnace gas, and associated petroleum gas typically contain a certain proportion of carbon dioxide (CO₂). Its presence not only reduces the combustion calorific value and utilization efficiency of the gas source but also causes severe corrosion to transmission pipelines and equipment. Meanwhile, as a typical greenhouse gas, direct emission of CO₂ will exacerbate global warming and impose environmental pressure. On the other hand, CO₂ is also an important industrial raw material, widely used in welding protection, food and beverage production, and many other industries. Therefore, separating and recovering CO₂ from combustible gases such as methane and carbon monoxide can not only enhance the utilization value of the gas source but also realize resource recycling, which is of great significance.

- Environmentally friendly operation, no secondary pollution, and low energy consumption.
selectively permeable membran
After the mixed gas undergoes dust removal, desulfurization, pressurization, drying, and purification, it enters the membrane separation unit. The membrane has preferential permeability to CO₂, forming a retentate stream rich in methane and a permeate stream rich in CO₂. The methane retentate stream is output as fuel gas, while the CO₂ permeate stream is compressed and condensed to obtain high-purity liquid CO₂.
