Principle of liquefied air

The design of the internal structure of the adsorber: the design of the internal structure of the adsorber includes the determination of the bed layer and various auxiliary structures, such as the design of the upper and lower filter, the guide valve, the pressing mechanism, the gas distribution device and so on. The adsorber can usually be divided into single bed and double bed, and the structure is shown in figure 3. Both the upper and lower vent of the two structures are equipped with filter and gas distributor. The single-layer bed structure is equipped with a screen hole plate and a cylinder compressing device on the molecular sieve adsorber. When the adsorber is working, the cylinder piston generates a lower thrust by differential pressure and compresses the molecular sieve through the screen hole plate, it avoids the phenomena that the molecular sieve is boiling and flowing and the filter screen is damaged due to the excessive airflow, thus prolonging the life of the molecula...

The air contains 0.932% of argon. When the upper tower wants to produce 99.6% of oxygen, it must contain 1.05% of argon in the nitrogen exhaust. From the perspective of the separation process, the stripping section (below the liquid-air inlet) in the upper column is basically an oxygen-argon separation, and the rectification section (above the liquid-air inlet) is basically a nitrogen-oxygen (argon) separation. . The boiling points of argon and oxygen are relatively close (the boiling point of o...
