Large air separation plant KDON (Ar)-18000/36000-600 solution for chemical industry
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.

Under the conditions of certain welding methods, welding materials, welding specification parameters and welding structure, the difficulty of obtaining high-quality welded joints is called steel weldability. Therefore, the weldability should be evaluated from two aspects of manufacturing and application. The weldability of process mainly refers to the possibility of various cracks in welded joints, which reflects the difficulty of manufacturing. Weldability of using mainly refers to the mechanical properties and special properties of heat resistance, corrosion resistance, low temperature resistance and fatigue resistance of welded joints, which reflects the reliability of use.

The volume fraction of carbon dioxide in air is generally around 0.03%, if the air compressor compresses the air to 0.62 MPa, the partial pressure of carbon dioxide can be calculated as 186 Pa. At the temperature when the air enters the air separation device, the saturated vapor pressure of carbon dioxide is much higher than the partial pressure of carbon dioxide, so carbon dioxide is in an unsaturated state, and carbon dioxi...
