Membrane-Based Gas Separation Solutions for Industrial Applications
Mairui Gas provides gas separation membrane modules and membrane-based systems for nitrogen generation, oxygen enrichment, CO₂ separation and gas dehumidification, supported by engineering design and system integration for project-specific requirements.
Membrane Technology
How Membrane Separation Works
Gas separation membranes use differences in permeation rates through hollow fibers. A pressure difference provides the driving force, while membrane selectivity allows different gases to become enriched in the permeate or non-permeate stream.
