There are three kinds of nitrogen production methods in industry: deep cold air separation, molecular sieve air separation (PSA) and membrane air separation. Among them, the application of high-purity nitrogen in industry is very strict. In some manufacturing industries, the purity of nitrogen is required to be over 99.99%. Industrial nitrogen air separation plant needs to adopt different process organization forms according to different product needs and geographical environment conditions. DEAR air separation strives to tap the energy-saving potential of equipment operation, and gradually forms a nitrogen production process with energy-saving characteristics. At the same time, customized and targeted design schemes are carried out according to the needs of different customers to meet the different needs of customers for industrial nitrogen production air separation plant.
