Nitrogen equipment is the most widely used in chemical industry,current, it is used in polyvinyl chloride (PVC),polypropylene (PE), polyethylene, aniline and maleic anhydride and ethanol, benzene anhydride, polyester, upper raw materials PTA, nitrogen protection for petrochemical products and polyformaldehyde products, also can be applied to the nitrogen purging in pipeline system, filling nitrogen storage tank, replacement, leak detection,protection for combustible gas, also applied to diesel oil hydrogenation and catalytic reforming.
More typical uses: the deactivation of the air layer above the storage liquid, Purge vessel, pipe, reactor and isolation chamber, synthesis fiber spinning, chlorination, equipment anti-corrosion,nitrogen filling in paint production to prevent the polymerization of oil drying,provide protective gas for oil tankers ( nitrogen sealing and purge gas on the oil surface),inert gas supply for marine engineering, dry quenching, oil fractionation, catalyst regeneration, nitrogen fertilizer raw materials, washing gas, catalyst protection, rubber packaging and storage, tire production, nitrogen injection for oil extraction,etc.
