Quantitative risk assessment is methodology based on calculating probabilities and frequencies of sequential events using Boolean algebra, and it is normally used to perform safety assessments for complex interacting systems. Although quantitative risk assessment has been commonly used in aerospace and nuclear industries, it can also be used for quantifying economic risk and for estimating possibilities of potential production losses in a petrochemical or a manufacturing plant. In developing quantitative risk assessment models for petrochemical plants, component failures as well as human (operator) errors are taken into consideration in developing the plant's fault‐tree logic, in which is used to predict probabilities of future plant upsets. This paper shows how the quantitative risk assessment can be used to rank the economic importance of the production units in a refinery for prioritizing maintenance activities. In addition, two case studies are compared to demonstrate how a quantitative risk assessment model can be used as an invaluable tool in process design optimization. The quantitative risk assessment methodology developed in this work relates production losses to the performance of the major components and the process design. This application of the quantitative risk assessment provides a basis for the risk‐informed decision‐making and optimizing allocation of plant resources in support of plant operation and maintenance activities. 相似文献

Large scale engineering process systems are subject to a variety of risks which affect the productivity and profitability of the industry in the long run. This paper outlines the short comings of the current methods of risk quantification and proposes a systems engineering framework to overcome these issues. The functionality of the developed model is illustrated for the case of mineral processing and metal production industries using a copper ore processing and refined metal production case study. The methodology provides a quantitative assessment of the risk factors and allows the opportunity to minimise financial losses, which would help investors, insurers and plant operators in these sectors to make appropriate risk hedging policies. The models developed can also be coupled with evolutionary or swarm based algorithms for optimising the systems. A numerical example is illustrated to demonstrate the validity of the proposition. 相似文献

无水氟化氢是化工生产的重要原料和产品,其生产、储存、运输和使用过程中都有发生事故的案例。因此,做好无水氟化氢的环境风险评价对于如何有效防范风险事故发生、确定安全范围以及风险事故发生后如何采取风险应急措施等都是非常必要的。以某氟化工企业的无水氟化氢生产为例,按照《建设项目环境风险评价技术导则》要求,通过重大危险源辨识、风险识别,确定无水氟化氢储罐泄露为最大可信事故。又通过源项分析、后果计算,对无水氟化氢储罐的泄露事故进行环境风险预测和评价,并提出了相关的风险防范措施,以期为同类型项目的环境风险评价提供可借鉴的经验。 相似文献
