Common faults of air separation unit system
Air separation unit maintenance procedures need to determine the maintenance cycle and content, maintenance quality standards, commissioning and acceptance maintenance and troubleshooting. Before the maintenance, the staff should prepare the air separation unit maintenance procedures according to the regulations, so as to avoid missing items and causing unnecessary economic losses. The staff should be familiar with the common faults of air separation unit system and deal with the emergency situation in time.

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.
Large air separation plant KDON-16000/35000 solution for metallurgical industry
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 Feed gas and cold source of the crude argon tower come from the main tower and return to the main tower, so the crude argon Tower and the main tower are closely related and affect each other. The input of crude argon tower should have the following conditions: 1) the working condition of main tower is stable; 2) the output and quality of oxygen and nitrogen products are close to or reach the normal value; 3) the argon content of argon fraction is close to normal; 4) the main cooling liquid level is relatively high with sufficient cooling capacity. In the process of the crude argon tower being put into use, first lead out the argon distillation to precool the crude argon Tower, and then gradually send the liquid air to the crude argon condenser. With the chilling of the crude argon Tower, the rectifying working condition is gradually established in the crude argon tower. Its mark is that the resistance of the crude argon Tower, the purity of the crude argon and the extraction amo...

The start-up of the air separation plant includes three stages: cooling, hydrops and purification. For a certain equipment, the start-up time is roughly certain. As for the low-pressure air separation equipment, there is no room to adjust the pressure of the air compressor. Generally, it depends on two expansion machines working at the same time to increase the refrigerating capacity in the start-up stage and shorten the start-up time. Even so, according to the maximum refrigeration capacity and the cooling required by cooling and Hydrops of the device, the start-up time of the device needs to be more than 36 hours. Large air separation plants are generally equipped with liquid oxygen storage tanks as emergency standby oxygen. If necessary, can liquid oxygen be filled into the tower to shorten the start-up time of the air separation plant? Theoretically, it is completely possible. For example, if filling 1M3 liquid oxygen into the main cooling, it is equivalent to providing 0.47 × 1...
