摘要
蒸汽加热器内漏导致分子筛解吸不彻底,二氧化碳穿透进入低压板翅式换热器并冻结堵塞通道,空分设备被迫停车处理。介绍故障经过、原因分析过程,阐述处理和预防措施。
The inner leakage of the steam heater results in incomplete desorption of the molecular sieve,penetration of carbon dioxide into the low-pressure plate-fin heat exchanger,blocking the passage,and forced shutdown of the air separation plant for treatment. The trouble course,the cause analysis process,the treatment and the preventive measures are described.
