Air separation training needs to learn, including air composition, basic principles of air separation, technical development of air separation process, air separation process flow, main technical indicators of air separation equipment, etc.
DEAR air separation has cooperated with customers in metallurgical industry domestic and abroad in many projects, and has rich project experience. DEAR has continuously invested in the research and development of large-scale air separation plant. In view of metallurgical industry, DEAR combined with the characteristic of this industry, develops high-efficiency energy-saving air separation plant, to meet the needs of large and medium customers. DEAR air separation uses the rapid development of internet technology to establish a remote monitoring system to collect real-time operation data of each air separation plant, and provides the best suggestions for users by using big data analysis.
Metallurgical industry is an industry to develop metal mineral resources and produce various kinds of raw materials for metal products. With the progress of science and technology, the metallurgical industry has new requirements for the process, process, management and application research and development of air separation plant. The air separation plant also has the following development trends: first, large-scale and cluster; second, the core technology is gradually localization; third, refinement, which needs to develop high-efficiency energy-saving technology for different application fields; fourth, highly automated and intelligent, reduce manual operation as far as possible, and gradually establish a remote monitoring system by using the rapid development of internet technology to collect in real time according to the operation data of air separation plant, using big data analysis to provide the best suggestions for users, etc. KDON (Ar) - 16000 / 35000, a large scale air separat
The pressure relief of molecular sieve in the purification system is generally rapid in the early stage, not complete and running overtime in the later stage. The pressure relief degree is adjusted by the manual stop valve in front of the pressure relief valve. Through practical adjustment, no matter how it is adjusted, the pressure relief in front is fast, or the pressure can not be exhausted. It is suggested that the valve positioner should be added to the automatic pressure relief valve, and the pressure linear adjustment should be programmed, so that the impact on molecular sieve will be much smaller.
Saturation temperature and saturation pressure are terms in gas-liquid equilibrium. If it is not filled with liquid in a sealed container, part of liquid molecules will enter the upper space, which is called "evaporation ". As the number of vapour molecules in space increases, the pressure of vapour generated by it also increases. At a certain time, the number of vapour molecules in space will not increase any more. At this time, the number of molecules leaving the liquid and the number of molecules returning the liquid from Space reach a dynamic balance, which is also called "saturated state ". At this time, the pressure generated by vapour is called "saturated pressure ". For the same substance, the saturation pressure is related to the temperature. The higher the temperature is, the greater the energy the molecule has, the easier it is to get rid of the liquid and gasification, and the corresponding saturation pressure is also higher. A certain temperature corresponds to a certai...
