In the chemical plant, nitrogen is mainly for the protection of gas, ventilation and washing gas, to ensure safe production.
Such as polypropylene production, it need to use pure nitrogen (99.99%) functioning as the protection of gas, replacement gas. High purity nitrogen is a vital source of chemical fiber production. Such as Liaoyang Petrochemical Plant has three sets of 3000 m 3 / hour high purity nitrogen device;Synthetic leather factory also use high purity nitrogen to do protection, such as Yantai synthetic leather factory has a 1000m3/hour high purity nitrogen device.
Forest chemical plants also use nitrogen, as a sensitive adhesive coating, rosin, resin and other production process of protective gas. It can be said that the chemical plant has a big demand for nitrogen, nitrogen is a chemical plant “security gas”. opening up chemical nitrogen is promising. Nitrogen is also an important raw material for synthetic fiber (acrylic, nylon) and synthetic rubber .
