During the operation of small air separation equipment, the reasons why the liquid enters into the heat exchanger are: 1) during the start-up stage, the valve of the distillation column is closed and the pressure-reducing speed is too slow, and the liquid oxygen level is too full, which makes the liquid enter into the heat exchanger. The symbol at this time is that the pointer of the pressure gauge of the upper tower fluctuates, the oxygen flow meter beats badly, and the temperature of T3 drops, with which the high and middle pressure automatically drops. When encountering this situation, the valve can be shut down and the pressure-down speed can be increased appropriately, and the large section-1 valve can be opened to increase the air flow through the second heat exchanger. And part of liquid oxygen can be discharged properly. When closing the small air, liquid nitrogen throttle or lowering pressure, it is normal for medium pressure to slightly rise (about 0.05MPa rise every 1 hou...

Air separation plant is one of the important production devices in petrochemical, metallurgy and other industries. Due to its special structure and physical and chemical properties of media, the risk of explosion is relatively high. In recent years, due to manufacturing defects and poor management of air separation plant, there have been many explosion accidents of air separation plant. According to incomplete statistics, there have been more than 100 explosion accidents of small air separation plant all over the country, there are more than 30 accidents of large and medium-sized air separation plant, especially the explosion caused by excessive hydrocarbon substances in the evaporator of air separation main condensing is the main reason for frequent accidents in recent years, which not only affects the smooth operation of production unit, and cause great economic losses to enterprises and the country. The following is a brief discussion on the explosion mechanism and explosion-proo...
