Big Data Application of Deep Cold Air Separation Equipment

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 ...
