本文介绍定量RBI分析方法在某石化公司环氧丙烷/苯乙烯装置风险评估中的实施过程,对装置中的容器和管道进行风险分析,并基于其潜在的损伤机理和风险等级给出适宜的大修检验策略。在保证检验有效性的前提下,优化检验资源,降低运行风险,以满足装置长周期安全稳定运行的需要。1环氧丙烷/苯乙烯装置简介及评估范围该石化公司位于我国东部沿海地区,环氧丙烷/苯乙烯装置于2010年2月建成投用,年产28.5万t环氧
This article presents the implementation of a quantitative RBI analysis method in the risk assessment of a propylene oxide / styrene plant in a petrochemical company, a risk analysis of vessels and piping in the plant, and an appropriate overhaul based on its potential damage mechanisms and risk levels Inspection strategy. Under the premise of ensuring the validity of inspection, resources are optimized and the operational risk is reduced, so as to meet the requirements of long-term safe and stable operation of the plant. Brief introduction and evaluation range of propylene oxide / styrene plant The petrochemical company is located in the eastern coastal areas of our country. The propylene oxide / styrene plant was put into operation in February 2010 with an annual output of 285,000 t epoxy
