Large air separation plant KDON (Ar)-12000/24000-400 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. For many years, DEAR air separation has provided a number of complete solutions for the metallurgical industry, relying on the deep understanding of the industry and excellent product quality to help the efficient development of the metallurgical industry. KDON (Ar) - 12000 / 24000-400, a large scale air separation plant cooperated by DEAR air separation company and customers, has realized the rapid, stable and efficient operation of the production process, which is highly affirmed by customers. It also provides strong technical and product support for customers to cope with the fierce market competition.
Small air separation plant KDON (Ar)-6500/6500-180 solution for metallurgical industry
Metallurgical industry can be divided into ferrous metallurgical industry and non-ferrous metallurgical industry. Ferrous metallurgy mainly refers to the production of pig iron, steel and ferroalloy (such as ferrochrome, ferromanganese, etc.), and non-ferrous metallurgy refers to the production of all metals except the former. 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) - 6500 / 6500-180 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.

As the air of the air separation plant of the molecular sieve purification process removes impurities such as moisture and carbon dioxide through the adsorption of the molecular sieve, compared with switching the purification process, the start-up operation is simple and easy to control. It doesn't need to consider the complex influences such as self-cleaning of water and carbon dioxide, precipitation of water and carbon dioxide in the expansion machine, and the attention of starting process mainly focuses on giving full play to the refrigeration capacity of the expansion machine, reasonably allocate cooling capacity and fully cool the equipment. It can be divided into three stages: cooling equipment, accumulation of liquid and adjustment of rectification working condition. Compared with the start-up mode of switching process, it can be called "comprehensive cooling method" or "one-time cooling method ". The following points should be paid attention to when starting the operation: 1...

Liquid air and liquid nitrogen supercooler uses nitrogen as cold source to cool liquid air or liquid nitrogen. There are Pipe type and plate type cooling device. When leakage occurs, it will affect the normal operation of the distillation column. It can be divided into two situations: 1) liquid air and liquid nitrogen leak to the nitrogen side. Since the liquid air leaks to the nitrogen side, it will be further recovered in the heat exchanger, so the increase of cold loss is not obvious, but the temperature at the cold end is Ding. Will drop, the cold end is too cold. If it is liquid leakage, because of the low concentration of nitrogen in liquid, the leak into the gas nitrogen will make the purity of gas nitrogen decline. After the leakage of liquid, the amount of liquid going into the tower will decrease and the recirculation fluid will decrease, which will worsen the rectifying working condition and decrease the oxygen output. In severe cases, the distillation tower will not work...
