◆ Product introduction ◆
?Process: filtration—fan—pressure swing adsorption module—compression—refrigeration—storage
?Equipment: filtration system, Roots blower—pressure swing adsorption 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 PSA purification CO2 device uses molecular sieve as the adsorbent, and uses the principle of PSA to separate CO2 from the gas. The separation effect of molecular sieve on CO2 and other gases in the gas is mainly based on the different diffusion speed of these two gases on the surface of the molecular sieve .The gas molecules with smaller diameter diffuse faster and more enter the pores of the molecular sieve. Gas molecules with a larger diameter have a slower diffusion rate and fewer enter the pores of the molecular sieve, so that more CO2 can be obtained in the gas phase.
?Application scenario: alcohol plant, natural gas decarbonization, etc
