What kind of unit is available in the air branch factory

Air separation equipment piston type liquid oxygen pump is widely used in liquid gasification station. The following requirements should be paid attention to when using: 1) all the parts, pipes, valves, sealing rings and so on contacting with oxygen must be strictly deoiled; 2) the oil level of the transmission device of the liquid pump should be checked frequently. The minimum oil level of the reduction box should not be lower than that of the big gear top, and the lowest position marked by the oil Rod should be measured; 3) When disassembling the internal parts of the liquid pump, there should be no dust in the working environment. Tools and work clothes must be clean and greasy. Clean parts should be blown dry with nitrogen to prevent moisture and dust pollution. All the orifice should be sealed with white cloth in case of entering the dirt and drawing the piston and cylinder; 4) the liquid pump should not be started before the precooling is complete. Do not operate under the con...

After the argon fraction is extracted from the top Tower, it enters into the crude argon tower and conducts the separation of oxygen and argon by the rectification method. Generally, the components of crude argon from the top of the crude argon tower are: argon is more than 98%, nitrogen is less than 0.5%, and oxygen is less than 1.5%. Import Crude argon with purity over 98% into molecular sieve adsorber. There are two adsorbers in each group. One is equipped with 5A Molecular sieve to absorb nitrogen in crude argon; the other is equipped with 4A molecular sieve to absorb oxygen in crude argon. In order to release the adsorbents, two groups of adsorbents need to be set up to switch to use. The adsorber works at the temperature of 90 K. The crude argon enters into 5A Molecular sieve adsorber to remove nitrogen first, and then enters into 4A molecular sieve adsorber to remove oxygen. The process is shown in Figure 18. The gas from a group of molecular sieve adsorbers has a purity of 9...
