Big Data Application of Deep Cold Air Separation Equipment

Another part of the nitrogen vaporized in the liquefier is heated up to a certain temperature in the high pressure heat exchanger and pumped out to the low pressure nitrogen press, the nitrogen separated by the gas-liquid separator is also heated up by the high pressure heat exchanger and then goes to the low pressure nitrogen press, compressed to a certain pressure by the low pressure nitrogen press and then back to the high pressure heat exchanger for heat exchange with liquid air separat...

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 ...
