Chemical and new material industry

Mainly used for chemical raw material gas, pipeline purging, atmosphere replacement, protective atmosphere, product transportation, etc. Mainly used in chemical, spandex, rubber, plastic, tire, polyurethane, biotechnology, intermediate and other industries. Many chemical industries do not require high nitrogen purity, and many can be used with a purity greater than 98%.

Chemical industry create an oxygen-free atmosphere in chemical processes to improve the safety of production processes, fluid transport power sources, etc.

Protective gas in replacement, cleaning, sealing, leak detection, dry quenching; catalyst regeneration, petroleum fractionation, chemical fiber production, etc.

Petroleum Industry Improvement of petroleum processing and refining processes, oil storage and pressurization of oil and gas field wells, pipeline cleaning and purging, solvent recovery, etc.

Nitrogen-filled purification of storage, containers, catalytic cracking towers, pipelines, etc.; air pressure leak testing of pipeline systems, etc.

Offshore oil development; gas capping of platforms in offshore oil exploration, inerting of oil, storage tanks, containers, etc.

Glass manufacturing prevents surface oxidation and furnace cooling during glass manufacturing.

Float glass Gas protection in the production process to prevent oxidation of the tin bath. Protective gas in float glass production

In the float glass industry, in the float glass production process, the float medium is easily oxidized under the high temperature of the tin bath, which increases the loss of tin and causes various defects on the glass surface. Therefore, it is necessary to pass the protective gas nitrogen into the tin bath. , At the same time, adding 5% to 10% of hydrogen, the tin bath forms a reducing atmosphere, and the tin oxide is reduced to tin again. By using Dürr gas's ammonia decomposition to produce nitrogen and hydrogen mixture instead of water electrolysis to produce hydrogen, and the practical application in many float glass production lines, the protective gas production equipment with low energy consumption, simple operation and relatively low safety and explosion-proof level is put into operation To the float glass production line, a beneficial exploration has been made to reduce the cost of hydrogen for the current production of low, medium and high-grade float glass.

Rubber vulcanization, tire crushing, etc. High pressure forming anti-oxidation, wire and cable gas protection.

Fertilizer industry: nitrogen fertilizer raw materials; gas for replacement, sealing, washing, protection catalyst, etc.

Plastics industry: pneumatic transmission of plastic particles; anti-oxidation in plastic production and storage, etc.

Rubber industry: packaging and storage of rubber; tire production, etc.

Application in chemical fiber production process: High-purity nitrogen is often used as protective gas in chemical fiber production to prevent chemical fiber products from being oxidized during production and affecting color. The higher the nitrogen purity, the more beautiful the color of chemical fiber products.
