Small air separation unit is the unit that separates air into oxygen and other gases by first compressing and cooling the air into a liquid state and then using the characteristic that oxygen has a different boiling point to other gases in the air to obtain oxygen and liquid oxygen by evaporation and separation, as well as other rare gases as required.Liquid oxygen is produced using the cryogenic separation of air. The basic principle is to u...

The pressure relief of molecular sieve in the purification system is generally rapid in the early stage, not complete and running overtime in the later stage. The pressure relief degree is adjusted by the manual stop valve in front of the pressure relief valve. Through practical adjustment, no matter how it is adjusted, the pressure relief in front is fast, or the pressure can not be exhausted. It is suggested that the valve positioner should be added to the automatic pressure relief valve, and the pressure linear adjustment should be programmed, so that the impact on molecular sieve will be much smaller.

What impact does the air volume of the air separation equipment have on the distillation tower?

There are several considerations for the maintenance of the oil cooler as follows. 1.The cooling water is purified fresh water. 2.To prevent scaling and improve the heat transfer coefficient, the cooling water temperature should be as low as possible and the water flow rate should be as large as possible. 3.In the cold season, in order to prevent the cooler heat transfer tube from freezing a...

What are the impacts of scaling in the cooling system of air separation equipment and how can it be prevented?

What are the requirements for cooling water in cryogenic air separation units?

What is the working principle of the cooling fractionation tower system in air separation equipment?

Under the conditions of certain welding methods, welding materials, welding specification parameters and welding structure, the difficulty of obtaining high-quality welded joints is called steel weldability. Therefore, the weldability should be evaluated from two aspects of manufacturing and application. The weldability of process mainly refers to the possibility of various cracks in welded joints, which reflects the difficulty of manufacturing. Weldability of using mainly refers to the mechanical properties and special properties of heat resistance, corrosion resistance, low temperature resistance and fatigue resistance of welded joints, which reflects the reliability of use.
