Oxygen-Enriched Membrane

‌Working Principle

The oxygen-enriched membrane leverages the difference in solubility and diffusion coefficients of nitrogen and oxygen in air when exposed to pressure differences across the membrane. Gases like water vapor and oxygen, which have faster permeation rates, pass through the membrane more readily, becoming oxygen-enriched gas. Nitrogen, with a slower permeation rate, accumulates on the retention side, resulting in nitrogen-enriched gas.





Product Features

The oxygen-enriched membrane incorporates several patented technologies, such as specialized oxygen nozzles, "localized oxygen enhancement," "gradient combustion," and "symmetrical combustion," achieving the following benefits:

Increased Flame Temperature and Blackbody Radiation: Significantly boosts radiant heat.

Lower Ignition Points: Enhances combustion speed and safety, helping to eliminate pollution.

Reduced Exhaust and Dust Emissions: Lessens environmental impact.

Lower Activation Energy: Makes combustion easier and more efficient.

Improved Heat Utilization: Achieves noticeable energy savings.

Reduced Excess Air Coefficient: Leads to energy and consumption reductions.

Glass Kilns: Saves 3-35% energy, increases production by 3-15%, and improves product quality.

Boilers and Furnaces: Typically saves 3-30% energy, with a significant reduction in harmful emissions.

Enhanced Stability: Stabilizes furnace conditions, reduces environmental pollution, and extends furnace lifespan.




Materials and Structure



Oxygen-Enriched Membrane Components: Available in spiral-wound, flat-sheet, and hollow-fiber configurations.

Spiral-Wound Membrane: Oxygen concentration of 28-31%.

Flat-Sheet Membrane: Oxygen concentration of 28-31%.

Hollow-Fiber Membrane: Oxygen concentration of 30-45%.

Oxygen Flow Rate: Ranges from 0.04 to 50,000 Nm³/h.

When the oxygen concentration is around 30% and scale is smaller than 50,000 Nm³/h, membrane technology investment, maintenance, and operation costs are only 66-98% of cryogenic and (V)PSA methods, making membrane technology particularly cost-effective for smaller scales.
