Actual operating conditions of large air separation unit heads
Due to the sudden expansion of the fluid boundary shape at the inlet receiver and the semi-circular flow interface, the flow state then changes dramatically and the main stream breaks away from the boundary to form a vortex, causing mechanical energy to be converted into thermal energy, resulting in a large energy loss.

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
Small air separation plant KDON (Ar)-4000/4000-110 solution for metallurgical industry
Metallurgical industry is an industry that exploits metal mineral resources and produces raw materials of various metal products, which is closely related to the national economy and people's livelihood. At present, Chinese iron and steel industry still has the situation of low concentration, insufficient capacity of high-end products and serious surplus of low-end products. DEAR air separation has provided a number of complete solutions for the metallurgical industry for many years, accumulated rich experience and helped the efficient development of the metallurgical industry. With years of service experience in the metallurgical industry, the small air separation plant KDON (Ar) - 4000 / 4000-110 cooperated by DEAR air separation and customers provides air separation plant with mature technology, stable equipment working condition, excellent performance and energy saving intelligence, which is highly recognized by customers.

In the air separation plant, the purity of oxygen is mainly determined by the working conditions of the distillation column at the upper and lower parts. In addition, the oxygen content in argon fraction, reflux ratio, number of theoretical trays and separation efficiency will have a direct impact on the purity of oxygen. The following is a brief introduction to the relationship between these factors and oxygen purity.

When the small air separation unit fractionation tower cooling start, in addition to into the booster compressor and directly into the air under the tower, air turbine compressor discharge air from the venting valve to keep the compressor discharge pressure unchanged. As the temperature of each part of the fractionation tower gradually decreases, the amount of air inhaled will gradually increase, at this time can gradually close the air compressor venting valve. When the cold end of the mai...
