◆ Product introduction ◆
?Process: filtration—compressor—membrane separation module—compression—refrigeration—storage
?Equipment: filtration system, compressor membrane separation module compressor (screw machine or reciprocating machine), refrigerator, separator, storage tank, etc.Scope of application: tail gas with a CO2 content of 40%~80%
?Features: Large operating flexibility, stable CO2 finished products, suitable for the separation of medium and high concentrations of CO2
?Principle: The membrane separation CO2 device uses advanced hollow fiber membrane separation technology to separate and purify CO2 from the gas. The working principle of the hollow fiber membrane is that different gas molecules are separated by different gas permeation rates in the hollow fiber membranes of polymer materials. The gas with a fast permeation rate is called "fast gas", and the gas with a slow permeation rate is called "slow gas". For example, water, H2S, CO2 and O2 in the gas are all "fast gas", while N2 and CH4 are "slow gas". Therefore, the selective permeation and adsorption characteristics of the membrane group determine that the membrane method can purify a large amount of CO2.
Application scenario: alcohol plant, natural gas decarbonization, etc
