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 order to realize the separation of oxygen and nitrogen in the air separation plant, the first thing is to make the air liquefaction, which must try to reduce the air temperature to the liquefaction temperature. The absolute pressure of the lower tower of the air separation tower is about 0.6MPa. Under this pressure, the temperature at which the air begins to liquefaction is about-172 ℃. Therefore, in order to make the air liquefaction, there must be a cold fluid with lower temperature to cool the air. As we know, the air separation plant is cooled by the inflated low temperature air. If the Air wants to expand, it needs to be compressed first, and the compression needs to consume energy. Air expansion can be through throttling expansion or expansion machine expansion. However, the temperature drop of this kind of expansion is limited. For high pressure air of 20MPa ℃ and 30℃, the temperature drop is only 32℃ when throttling to 0.1MPa. In the turbine expander, the maximum temperat...

Air separation plant is an important supporting facility for large-scale industrial enterprises, such as chemical industry, smelting industry, electronics industry and energy industry. Its operation condition is very important to the enterprise. In the actual production, the air separation plant is often be shut down by mistake due to many factors, such as instrument control incorrect interlocking, manual incorrect operation or network voltage fluctuation, which causes great losses to the enterprise. Here are a few preventive measures for incorrect shutdown.
