Why is the ASU cold box the core area for air separation?

What is the impact of changes in environmental conditions on the performance of air separation equipment?

The liqued air separation plant cooling capacity is cooled between the air compressor and the nitrogen compressor, resulting in a significant reduction in energy consumption and a 50% saving in energy consumption. At the same time the introduction of liqued air separation plant cold capacity eliminates the chiller, expander, but increases the cold balance of the liquefier, in the heat transfer calculation is more difficult in low temperature conditions, the performance of the fluid changes more ...

When the air separation unit is in normal operation, the liquid flows down and can only flow on the tray and flow to the lower tray through the overflow bucket because the supporting force of the rising steam prevents the liquid from flowing down from the small hole of the tray. After shutdown, due to the interruption of rising gas flow, the liquid on the tray can flow from the overflow bucket to the lower tray, and also can flow through the small hole on the tray to the lower tray. This will cause the surface of liquid oxygen and liquid air rise, which may exceed the position of the expansion air outlet pipe, resulting in liquid carrying accident of the expander during restart. Therefore, pay attention to the liquid level position when stopping.

What is the reason why there may be multiple peaks in the cold blowing curve of the molecular sieve purifier of the air separation equipment during regeneration

Why do air separation equipment remove impurities in the air?

What impact does air volume of air separation equipment have on rectification tower?

  Since the successful development of the first set of high-purity nitrogen air separation unit in China in 1978, the R & D breakthrough of domestic nitrogen production equipment has closely followed the pace of foreign countries, and has achieved leapfrog development in recent decades. At the same time, China's nitrogen production market also shows an upward trend year by year, and the demand for nitrogen p...
