Troubleshooting of air separation equipment

When the demand for oxygen increases higher than the normal working condition, more liquid oxygen is extracted from the liquid oxygen storage tank, pressurized to the required pressure by the liquid oxygen pump and sent into the main heat exchanger after gasification and reheating, and the liquid oxygen stored in the liquid oxygen storage tank is consumed. At the same time, the flow of low-pressure expander will be reduced, and more cold volume will be recovered by high-pressure nitrogen and the...

The liquid air separation plant system uses the cold energy to produce liquid oxygen, liquid nitrogen and liquid argon in an air separation system, including an air compression pre-cooling system, an air purification system, an air separation system and a nitrogen circulation system for liquid air separation plant cold recovery. the nitrogen circulation system for liquid air separation plant cold recovery is placed in a separate cold box from the main cold box of the air separation system. the l...
