Categorized Into Five Major Areas Of Application

Storage Tank Blanketing (Most Common Use): A slight positive pressure of nitrogen is maintained in the headspace of tanks storing crude oil, gasoline, aromatics, and LPG to displace oxygen. This prevents the oxidation and deterioration of oil products, inhibits gum formation, and dilutes hydrocarbon vapors. It effectively eliminates the three prerequisites for combustion and explosion, significantly reduces the volatilization losses of light components, and—being dry and free of moisture—protects tank walls against corrosion.

Plant Start-up / Maintenance: Displacement & Purging (Pre-Start-up): Nitrogen is used to displace air from towers and pipelines, reducing oxygen levels to safe thresholds to prevent explosions during hot work or feedstock introduction. Shutdown & Maintenance: Nitrogen purges hydrocarbons, oil vapors, and toxic media; entry into vessels for operations is permitted only after safety clearance is obtained. Shutdown & Pressure Holding: Equipment is sealed under a nitrogen blanket to prevent moisture ingress, rusting, and air backflow.

Reaction Process Protection: Hydrogenation, Catalytic Cracking, Polymerization (PE/PP): An oxygen-free atmosphere is maintained within reactors to protect catalysts from burnout, prevent material oxidation, and enhance product purity. Stripping & Distillation: Hot nitrogen carries away light components and solvents to purify oil products. Catalyst Regeneration & Reduction: Inert protection is provided throughout the entire regeneration and reduction process.
