Size of the air separation unit

Size of the air separation unit
Generally, the size of the air separation unit is measured by oxygen production, and the unit is Nm3 / h, which means how many cubic meters are produced per hour. The size of the air separation plant needs to be selected according to the actual production needs of the enterprise, not the larger the better.

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.

The lower and upper columns are the main equipment in the distillation system of cryogenic oxygen air separation plant. The lower column and the upper column separate the components of the mixture gas into different components with the required purity by using the different boiling points. The upper and lower columns are of cylindrical structure. The lower column is equipped with multi-layer sieve plates, and the sieve plate is equipped with overflow bucket. There is an overflow baffle with dense holes. The upper column is equipped with regular packing and liquid distributor. In the distillation process of the lower column, the liquid flows through each sieve plate one by one from top to bottom. Due to the effect of overflow weir, a certain height of liquid level is created on the pedal. When the gas passes through the small hole of sieve plate from bottom to top, it contacts with the liquid and produces bubbles, which increases the gas-liquid contact area and makes the heat and mass e
