Large air separation unit argon extraction rate

Large air separation unit argon extraction rate
In adjusting the argon system working conditions must be adjusted at the same time air separation main tower good crude argon tower working conditions, in order to obtain the highest possible argon extraction rate, the impact of argon extraction rate has many aspects of the reason.

The principle of expander with motor brake in air separation plant is to control the speed of expander by braking torque generated by motor generator braking state. Once the brake motor fails, the expander speed will lose control and overspeed will occur. At this time, it is necessary to automatically open the protection and control system. The principle is that the speed measuring motor will send out the overspeed signal to cut off the three-way solenoid valve. The three-way solenoid valve directly controls the air open pneumatic butterfly valve at the inlet of the expander, so that the butterfly valve is quickly closed and the air inlet is cut off. At the same time, the rotation of the valve rod touches the stop and limit switch, so that the power supply of the expander motor is cut off and the safe shutdown is realized.

In the air separation plant, the purity of oxygen is mainly determined by the working conditions of the distillation column at the upper and lower parts. In addition, the oxygen content in argon fraction, reflux ratio, number of theoretical trays and separation efficiency will have a direct impact on the purity of oxygen. The following is a brief introduction to the relationship between these factors and oxygen purity.
