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.

When the working condition of the air separation plant is stable, the cooling capacity of the unit keeps balance with the cooling capacity consumption, and the temperature, pressure, liquid level and other parameters of each part in the unit no longer change with time. The main cooling is the bond connecting the upper tower and the lower tower. The rising nitrogen from the lower tower is heated and condensed in the main cooling, and the reflux liquid oxygen from the upper tower is absorbed and evaporated in the main cooling. When the amount of recirculation liquid is equal to the evaporation, the liquid level remains unchanged. When the processed air enters the tower, it has certain "moisture content", that is, a small part of it is liquid. Most of the air will be liquefied in the main cooling. As for the low-pressure air separation equipment, the air going into the tower is composed of the air at the cold end of the main heat exchanger and the air passing through the liquid purifie...

At the beginning of starting the full low pressure oxygen generator, all the air entering the equipment is inflated through the expander, while the total expansion volume of the expander (including the standby) set by the equipment is much smaller than that of the air compressor. In addition, at the beginning, the intake temperature of the expansion machine is much higher than the design value, and the actual air volume that can enter the expansion machine is less than the design expansion volume. Therefore, there must be a part of air to be emptied first, in order to avoid the air compressor overpressure or surge. When the liquid begins to accumulate, air is sent to the lower tower, then through the throttle throttle to the upper tower, and then combined with the expansion gas to the heat exchanger to recover the cooling. However, at the beginning, the air that can be eaten in the air separation tower is very small, because the liquid air, liquid nitrogen pipeline and regulating va...
