Cold and heat exchange in liquid air separation plants

Cold and heat exchange in liquid air separation plants
The air brings the cooling source to the lower tower through heat exchange, while the temperature drop after expansion also depends on the mid and bottom pumping temperatures of the main heat exchanger, which in turn derive directly from the cooling temperature of the upper tower.

Solutions of Cold and heat exchange in liquid air separation plants
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.
Large air separation plant KDON-20000/20000 solution for metallurgical industry
DEAR air separation has cooperated with customers in metallurgical industry domestic and abroad in many projects, and has rich project experience.

Faq of Cold and heat exchange in liquid air separation plants
1.Operators should adjust the discharge volume in time so that the concentration times are within the index. 2.Every week, a large amount of sewage should be discharged once. Discharge the sewage from the drainage pipe at the bottom of the tower. 3.Regularly analyse the calcium loss rate. Calcium loss rate is used to assess the system scaling situation, in general, calcium loss rate ≤ 20%. 4.Monitor the cooling water analysis once a week. Main analysis items: pH, conductivity, total phosph...
