1.Why remove impurities during air separation. As the air cools, the frozen water and carbon dioxide are deposited in a cryogenic heat exchanger, a turbine expander, or a distillation tower, blocking passages, pipes, and valves. Acetylene accumulates in liquid oxygen and is in danger of explosion. Dust can wear away the running machinery. In order to ensure the long-term stable and reliable operation of air separation equipment, special purification equipment must be set up to remove these impurities. 2.How to judge whether the heat regeneration of molecular sieve is complete? Firstly, the gas pressure and flow required to heat the molecular sieve are required to meet the process requirements.Heating regeneration process can be judged by regeneration curve. “Cold blast peak”

Condenser Evaporator reached by our company XLA and post-doctors of Nanjing University of Aeronautics and Astronautics was successfully held. Professor-level senior engineer, evaluation experts Jiang Chubiao and Xi YongLong, the professor Si Haiqing of Nanjing University of Aeronautics and Astronautics, Wang Qunfeng and Zhang Jianyun of Human Resources Service Center development zone, our general manager Xue Lu and our main technical backbone attended the opening review meeting.
