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

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

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.

Solution advantages

Solution advantages

The unit adopts molecular sieve purification, booster turbine expander to supply the cooling capacity of the unit, and the whole rectification hydrogen-free argon production process, which is safe, reliable and economical. The main reasons are as follows:

 

1.Good safety

The whole set of device has the advantages of low operating pressure, simple process, high equipment safety, long switching cycle of molecular sieve system, increased service life of switching valve, and reduced potential hazards.

A large amount of liquid oxygen is extracted from the main cooling (K1) to minimize the possibility of hydrocarbon accumulation.

 

2.High reliability

A large amount of surplus nitrogen can be sent to the water cooling tower, reducing the load of the water chiller, reducing the energy consumption and cost of air separation, so that the reliability of the device is further improved.

 

3.Convenient operation and maintenanceandsimple process
