Liquid air separation plant cold energy utilises air separation equipment, generally large air separation equipment with 2 combined expanders. The price is around 4 million RMB. The expansion air in the air separation plant is no longer required, so for the internal compression process air separation, the inlet air volume of the circulating booster is reduced by about 40% (from 5.A-2A). The energy consumption of the booster is reduced and the investment is reduced. Liquid air separation equipmen...

Effective energy analysis is an important analytical method for energy systems. liquid air separation plant is a low-temperature liquid mixture with methane as the main component, including nitrogen, ethane, propane and other components, which has a large temperature difference and pressure with the outside world. liquid air separation plant is a low temperature liquid and its temperature rise is accompanied by phase change heat, so its cold energy is divided into sensible heat and lat...
