Chemical industry has the characteristics of large scale, long industrial chain and so on. It is the basic industry and an important part of Chinese national economy. In recent years, environmental protection has been paid more and more attention, and the green development of chemical industry is also very important. In addition, the chemical industry in the industrial integration, scientific and technological innovation is also in constant efforts to advance. DEAR air separation helps the chemical industry to transform and upgrade to be environmental-friendly. DEAR’s large-scale air separation plant KDON (Ar) - 18000 / 36000-600 can use ultra-low pressure discharge energy-saving air separation technology patent, which can reduce the energy consumption of equipment operation by 5% - 15% and save a lot of production costs.
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.
The main measures taken for the design of oxygen piping in small air separation unit.
1、The piping material of the high-pressure oxygen gas pipeline is made of stainless steel to reduce the possibility of iron oxidation and combustion under intense working conditions.
2、Partial commercial flow rate piping using copper brocade alloy (Monel);
3, the use of different conditions of the pipeline proposed different degreasing and cleanliness requirements in the selection of Tong expansion joint for...
The raw air is compressed to about 0.52Mpa by the air compressor after filtering out dust and impurities, and then cooled to about 10℃ by the refrigerant glycol aqueous solution or Freon, and then enters the purification system to purify and remove water, carbon dioxide and other impurities in the air. Part of the raw material air enters the lower tower via the second raw material air pipeline, another part is liquefied into liquid air via the liquefier and enters the lower tower via the liquid ...
