The energy consumption of liquid air separation is mainly the energy consumption of compressor, which reduces the operating pressure to reduce the power consumption of air compressor.Therefore, the resistance of equipment and pipelines should be reduced as far as possible to reduce the pressure of the upper tower, and a certain level of main cooling liquid should be maintained so that the main cooling can work under the best heat transfer condition to reduce the temperature difference of the main cooling and the pressure of the lower tower, and to minimize the cold loss.Improve the efficiency of the compressor.First, we must strengthen the management of the intermediate cooler so that the air can be cooled well.Increase air volume.In order to reduce switching loss and eliminate leakage, more process air can enter the tower to participate in separation.
