Product Overview
The CO₂ separation membrane is a high-efficiency membrane designed for decarbonization and purification of natural gas, biogas, and industrial flue gas. Leveraging the membrane’s preferential permeability to CO₂, the system separates gases under a pressure differential, producing a product stream on the non-permeate side with reduced CO₂ content. This enhances gas purity and resource utilization. The compact and stable system is suitable for natural gas upgrading, exhaust gas treatment, and industrial emission reduction applications.
Working Principle
The decarbonization process relies on the differences in diffusion and solubility of gas molecules through the membrane. CO₂-containing gas enters the membrane under a pressure gradient. Due to its high permeability, CO₂ preferentially permeates the membrane to form the permeate stream, while the non-permeate side delivers high-purity product gas, typically methane. This process operates at mild temperatures and pressures without phase changes, allowing continuous operation with high economic efficiency and sustainability.
