The chemical industry is the most widely used industry of nitrogen equipment, mainly used in the fields of chemical industry, spandex, rubber, plastic, polyurethane, biotechnology, etc., in the production links of chemical raw material gas, pipeline purge, atmosphere replacement, protective atmosphere, product transportation, etc. Play an important role.
Chemical synthesis: Nitrogen is mainly used to synthesize ammonia and is an important raw material for synthetic fibers (nylon, acrylic), synthetic resins, and synthetic rubbers.
Chemical industry: protective gas in replacement, cleaning, sealing, leak detection, dry coke quenching; gas used in catalyst regeneration, petroleum fractionation, etc.
Fertilizer industry: As a nutrient element, nitrogen can be used to make fertilizers, and it can also be used as a protective gas in the processes of replacement, sealing, washing, and so on.
Plastic industry: pneumatic transmission of plastic particles; anti-oxidation in plastic production and storage, etc.
Rubber industry: packaging and storage of rubber; tire production, etc.
Chemical fiber production: In chemical fiber production, high-purity nitrogen is often used as a protective gas to prevent chemical fiber products from being oxidized during production and affecting the color. The higher the purity of nitrogen, the more beautiful the color of chemical fiber products.
