The cryogenic nitrogen production project (project number: 4013) constructed by NUZHUO in Shangluo, China, has successfully completed the construction of key nodes. This marks another verification of NUZHUO's full industrial chain capabilities in the field of cryogenic air separation. The advancement of this project not only provides a solid guarantee for the industrial gas supply in Shangluo and its surrounding areas, but also becomes another benchmark case for NUZHUO's deep engagement in air separation equipment manufacturing and its contribution to national industrial upgrading.
The core of Project 4013 is a highly efficient and high-purity cryogenic nitrogen production system. Unlike the traditional pressure swing adsorption (PSA) nitrogen production method, the cryogenic nitrogen technology is based on the principle that different components in the air have different boiling points. Through deep cooling and distillation, it can produce high-purity nitrogen on a large scale, with continuous and stable output, especially suitable for the chemical, electronic, metallurgical and new energy industries that have extremely high requirements for nitrogen purity, usage and stability.
NUZHUO's cryogenic nitrogen production solution for this project fully demonstrates its technical expertise in purity guarantee and energy efficiency optimization. Nitrogen purity is the "lifeline" for evaluating the performance of the equipment. NUZHUO adopts efficient structured packed distillation tower technology, combined with imported high-end molecular sieve dual adsorption system, to deeply remove moisture, carbon dioxide and hydrocarbons from the air, ensuring that the final nitrogen product purity reaches the industry-leading level, which can precisely meet the strict requirements of high-end manufacturing processes for gas impurities. At the same time, this device is equipped with intelligent online monitoring and DCS automatic control systems, which can adjust the distillation conditions in real time according to load changes, ensuring the long-term stability of product purity.
Under the guidance of the "dual carbon" goal, energy conservation and consumption reduction in industrial production have become a key issue. The NUZHUO cryogenic nitrogen generation equipment stands out in its energy-saving design. Its compression system uses low-power compressors and combines intelligent pressure regulation technology. It can automatically adjust the output power according to the actual gas consumption, avoiding energy waste. In the refrigeration process, the heat exchanger structure is optimized to improve heat exchange efficiency, and an energy recovery device is installed to convert the excess energy generated during the expansion process into electrical energy, further reducing operating costs.
According to industry application data, compared with traditional equipment, the unit nitrogen production energy consumption of NUZHUO's similar cryogenic nitrogen production units has significantly decreased. While ensuring a stable output of high-purity nitrogen gas above 99.9%, it can save considerable long-term operating costs for enterprises. This not only aligns with the policy orientation of promoting industrial green development in Shangluo region, but also brings tangible economic benefits to the project owner.
