Core Functions

1. Oxygen isolation and anti-oxidation: Isolate air to prevent raw materials, intermediates and finished products from oxidative deterioration, and avoid material discoloration, performance failure and increased side reactions.
2. Flame retardancy and explosion prevention: Dilute the concentration of flammable and explosive gases and liquid vapors to below the explosive limit, eliminating risks of combustion and explosion.
3. Moisture proofing and hydrolysis prevention: Block water vapor to stop moisture-absorbing and hydrolysis-prone chemical materials from deteriorating and caking.
4. Inert pressure stabilization and air replacement: Replace the air inside pipelines, reaction kettles and storage tanks to form an inert atmosphere in closed systems.
5. Sealing and pressure maintenance: Fill nitrogen into equipment shaft seals, valves and reaction systems to stabilize pressure and prevent infiltration of external air.   

   Mainstream Chemical Industry Application Scenarios
   
   1.Fine Chemicals / Synthetic Reactions
   Nitrogen is continuously introduced throughout organic synthesis, polymerization, hydrogenation and dehydrogenation reactions to create an oxygen-free inert atmosphere, ensuring reaction purity and yield.

   2.Storage Tank Protection

   Nitrogen blanketing is applied to storage tanks of methanol, ethanol, aromatic hydrocarbons, organic solvents and hazardous chemical liquids. Nitrogen filling above the liquid surface isolates air to prevent volatilization, oxidation, combustion and explosion risks.

   3.Purging and Replacement of Pipelines and Equipment

   Nitrogen is used to replace air and flammable gas inside pipelines and reaction kettles before maintenance, feeding and shutdown, enabling safe start-up and shutdown of equipment.

   4.Powder Chemical Industry

   Nitrogen filling is adopted during the transportation, mixing and packaging of chemical powder materials, resins, pigments and pesticide powders to avoid dust oxidation and electrostatic ignition.

   5.Pharmaceutical Chemicals / Intermediates

   Nitrogen atmosphere is applied in the production and storage of highly active pharmaceutical raw materials and biochemical raw materials to guarantee drug efficacy and chemical stability.

   6.Coal Chemical Industry / Petrochemical Industry

   Inert gas protection is provided for cracking, rectification and hydrogenation units, and nitrogen blanketing is used for oil and gas storage and transportation to realize fire and explosion prevention in high-risk working sections.

   7.Electroplating and Chemical Heat Treatment

   Nitrogen serves as protective atmosphere for heat treatment and surface modification of chemical materials.
