湿Ｈ２Ｓ环境中硫化物腐蚀开裂问题（ＳＳＣ、ＨＩＣ、Ｂ－ＨＩＣ、ＳＯＨＩＣ）是炼制含硫原油时中、高强钢制液化石油气球罐一种常见而且经济损失很大的损伤形式。文中探讨了ＬＰＧ球罐所面临的湿Ｈ２Ｓ环境、非脱水ＬＰＧ球罐中水的分布，提出了中、高强钢ＬＰＧ球罐湿Ｈ２Ｓ开裂的监控与预防措施。
Sulfide corrosion cracking in wet H2S (SSC, HIC, B-HIC, SOHIC) is a common and economically damaging form of damage to medium- and high-strength steel liquefied petroleum gas (LPG) spheres when refining sour crude oil. In this paper, the wet H2S environment of LPG spherical tank and the distribution of water in non-dehydrated LPG spherical tank are discussed. The monitoring and preventive measures of wet H2S cracking of medium and high strength steel LPG spherical tank are proposed.
