| Abstract: | Because of leakage from steam heater of the molecular sieve purification system in 60000 m^3/h air separation plant, the carbon dioxide content in air from outlet of molecular sieve adsorber exceeds the specified value, the resistance increase due to icing of passage of the main heat exchanger, and the air separation system is forced to stop for warming and special regeneration of molecular sieve. Here, the trouble course is briefed, the causes for carbon dioxide penetration are analyzed, and the corrective measures and future lessons are described |
