Nitrogen is a widely used industrial gas, which is mainly used in electronic packaging, chemical processing, lighting, heat treatment, food packaging, food freezing, metal manufacturing, glass production, biopharmaceutical and other industries. At present, the most widely used high-purity nitrogen air separation unit mainly uses the method of low-temperature distillation to produce high-purity nitrogen. The high-purity nitrogen air separation unit manufactured by DEAR air separation plant can obtain high-purity nitrogen and save operation electricity cost for the enterprise. DEAR has two ultra-low pressure discharge energy-saving patents, which can reduce the energy consumption of the equipment by 5% - 15%.
