The main energy consumption is compressed air, followed by compressed oxygen.Therefore, the energy consumed to produce 1 m3 of oxygen (kW h) is usually used as an indicator to measure the performance of air separation oxygen production.The energy consumption of the compressor is related to the amount of compressed air, the exhaust pressure and the efficiency of the compressor.We should start from the following aspects: 1. Reduce the operating pressure of oxygen generator to reduce the power consumption of air compressor.2.Improve the efficiency of the compressor.3.Increase air volume.4. Increase oxygen yield and oxygen extraction rate.5. Extend the continuous operation cycle of equipment and reduce the downtime.6. Absolutely avoid leakage of low temperature liquid and gas in the tower.
