分子筛纯化系统蒸汽加热器内漏故障排查与处理

摘要

本钢氧气厂7#35000 m3/h空分设备于2015年3月发生了一起分子筛蒸汽加热器内部泄漏故障。故障发现及时，果断停机后，对漏点进行了排查和处理，避免了次生事故的发生。为制氧机组开车复产赢得了时间，节约了检修时间和成本。%An accident of leakage in the molecular sieve steam heater of the No.7 35000 m3/h air separation plant at Benxi Steel happened in March 2015. As the accident was discovered in time, the oxygen generating unit was immediately shut down and leaking points were searched and treated promptly, preventing more serious secondary accidents from happen-ing. The timely treatment of the accident had gained precious time for the oxygen making unit resuming production and saved maintenance time and cost.
