CO2 Membrane

‌Working Principle

The basic principle of membrane-based natural gas decarbonization is to utilize the membrane’s preferential permeability to CO2. Under a certain pressure difference, CO2-rich natural gas passes through the selective membrane, allowing CO2 to permeate first. This results in a product gas with low CO2 content on the non-permeable side.

Features of CO2 Membrane

•  Compact size and lightweight

•  Simple process flow, high reliability, and low operating costs

•  Methane product meets fuel gas standards while efficiently recovering CO2 with high selectivity

•  Suitable for biogas purification of various scales, with CH4 purity and recovery rates exceeding 95%

•  In two-stage membrane separation, using low-temperature recovery units, CO2 purity can reach over 99.9%
