摘　　要：采用RBI技术对某厂加氢精制装置的部分在用压力容器进行了定量风险评估。结果表明,该装置当前的风险水平较高,其中失效可能性3级以上的设备项占25.0%,中高风险项及以上的设备项占16.7%,主要损伤为碱性酸性水腐蚀和湿硫化氢环境下的损伤。经停机检验验证,评估结果准确,此次定量风险评估为装置的日常安全管理提供了依据。Quantitative risk assessment has been conducted for some pressure vessels in-service of the hydrotreating plant. The results showed that this hydrotreating plant was at a high level of risk, and the assessment units which likelihood Category were above category 3 accounted for 25.0 % and the assessment units with medium-high risk rank or above accounted for 16.7 %. The main damage mechanisms of the equipments was ammonium bisulfide corrosion and wet H2 S damage.
