Air separation equipment is a complete set of equipment composed of various machines and devices, and is often classified according to air pressure. The three common types are high-pressure, medium-pressure, and low-pressure.
When selecting the type of equipment, factors such as product type, capacity, and purity requirements, as well as power consumption and safe continuous operation cycle, should be considered.
Low-pressure equipment is widely used due to its low power consumption, long continuous operation cycle, and high economic efficiency.
Low-pressure air separation equipment consists of four main systems: an air compression system, an impurity purification and heat exchange system, a refrigeration system, and a liquefaction and distillation system. The corresponding mechanical equipment includes air turbine compressors, air cooling towers, turbine expanders, and distillation columns.
