On-site nitrogen: Autonomous fire prevention for remote mines

Air Liquide’s membrane technology is the most reliable choice for demanding coal mining environments. Delivering nitrogen to remote, isolated mine sites is a major logistical challenge. Our Nitrogen Production Units (NPUs) solve this by providing a seamless, on-site 'plug and play' generation system. Trusted in over 2,000 locations globally, our rugged units deliver continuous nitrogen (95% to 99.9% purity at 35 barg) directly to the galleries to help suppress spontaneous combustion.

Core benefits of our membrane solutions:

Eliminate supply chain risks: By generating nitrogen on-site, mines completely remove the dependency on external gas deliveries, drastically optimizing both CAPEX and OPEX.
Maximized productivity: Our highly selective membranes are engineered to guarantee a continuous, high-volume flow of N₂to secure your mining operations from a single installation.
Compact & rugged design: The highly productive hollow fiber technology minimizes the space required for installation, allowing for flexible positioning near critical mining infrastructure.
Standards and safety: Built for harsh environments, our systems are designed to the highest safety standards (ISO9001 and ASME U stamped) and can be tailored to suit specific mining regulations.
Simple maintenance: All membranes can be replaced with ease by simply inserting them into the original pressure vessels, minimizing operational downtime.

Air Liquide membranes have high productivity and selectivity. Our unique manufacturing process produces extremely small diameter fiber which transposes into smaller bundles than typical N₂ membranes, resulting in space and weight savings. Our membranes can operate up to 35 barg pressure and produce purities up to 99.9%. All our N₂ membranes can reuse existing vessels to save cost and wastage.

Frequently Asked Questions (FAQ)

How do Air Liquide's membrane systems ensure reliable N₂ supply for coal mine fire prevention in remote areas?

Our advanced membrane generator systems provide a reliable, fully autonomous, and low-cost on-site nitrogen supply, directly at your mine site, eliminating the logistical complexities and re-ordering delays of traditional external gas supply. This on-site N₂ generation is proven in demanding environments like Australian coal mines.

Australian coal mines in remote areas use Air Liquide FLOXAL technology to provide a continuous supply of gaseous N₂ to control the potential for fires which ultimately leads to a safer working environment.

Coal Mines can suffer from fires due to spontaneous combustion which is caused by air mixing with coal resulting in low temperature oxidation generating heat. Injecting gaseous N₂ in the affected area will reduce the oxidation and prevent or extinguish fires.
