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 in the same heat exchanger, there are multiple strands of fluid for heat transfer. lng if in a supercritical state, the heat transfer process is more complex, to be considered comprehensively cold, hot end temperature difference, logarithmic mean temperature difference, minimum temperature difference, making Cold loss not to be too large.
Liquid air separation plants production of liquid oxygen, liquid nitrogen, liquid chlorine products are widely used in metallurgy, petrochemical, machinery, fertilizer, glass, military food, medical and other fields. Traditional conventional air separation energy consumption is large, the production of liquid products need 1.05-1.2kwh of energy consumption to use. Liqued air separation plant cold energy produce liquid products to reduce energy consumption by more than 50%, or even the whole liquid air separation plants completely don't need any electricity.
The liqued air separation plants and small air separation units and largeair separation units designed and produced by Dear Air Separation have the characteristics of high safety, energy saving and low energy consumption and full housekeeping operation and maintenance services.
