某石化公司脱硫装置低分气分液罐在湿硫化氢环境中运行，检修时发现罐体外表面出现严重的鼓泡现象。本文利用气体取样装置测定鼓泡内气体为氢气，并通过宏观检查、金相组织分析、扫描电镜分析和能谱分析等测试方法对低分气分液罐氢鼓泡原因进行分析和研究，结果表明，长条形MnS夹杂物是导致罐体表面产生氢鼓泡的重要原因。在此基础上，提出氢鼓泡预防措施。

Serious blisters were found on the shell surface of the gas tank which operated in wet H2S environment during a regular inspection. It was confirmed with gas sampling device that the gas in the blister was hydrogen. The causes of blisters were analyzed and investigated by chemical analysis, metallographic examines, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results revealed that the elongated MnS inclusions were the important reason for the hydrogen blisters. The preventive measures of the hydrogen blisters were put forward based on the above study.
