Small air separation FAQ

1, gas welding of purple copper plate: welding purple copper plate is most commonly used for butt joints, lap joints and ding joints are used as little as possible. Gas welding can be used in two kinds of welding wire, one containing deoxidizing elements, such as wire 201, 202; the other is the general purple copper wire and the cutting strip of the parent material, using gas 301 as flux. Gas welding purple copper should be used when the neutral flame. 2, manual arc welding of purple copper: in...

The required steam pressure, flow rate, etc. should meet the process design requirements when the molecular sieve is heated. The heating regeneration process in small air separation unit can be judged by the regeneration temperature curve. In the unloading stage, the adsorption capacity of the molecular sieve decreases due to the pressure drop, and some of the water and carbon dioxide molecules originally adsorbed are desorbed, and the temperature drops. In the heating stage in small air ...

This project we use nitrogen booster cycle in the design process of oxygen compression fast variable load process. The process in small air separation unit before the air leaves the molecular sieve is the same as the conventional process, and the air after leaving the molecular sieve purification unit is cooled in the main heat exchanger and then enters the pressure tower. The flow of the nitrogen booster cycle is ...
