Abstract

This study aims to establish a theoretical framework using inherent safety concepts to prevent pool fire domino effects during the layout planning stage of chemical storage tank farms. Firstly, the probit and point source thermal radiation models are adopted to capture the accident escalation processes. Then, the principles of dynamic heat radiation synergies are proposed by integrating the thermal radiation intensity at different time steps. Subsequently, Bayesian networks are used to determine the accident topology of domino effects and the failure probabilities of target tanks. Lastly, the failure probabilities are weighted and reconciled using the Analytic Hierarchy Process (AHP) and tank location importance to develop a quantitative risk assessment tool termed Knock-on Risk Index (KRI). The case study demonstrates that the KRI values of alternatives A, B, and C are respectively 2.51E+ 05, 1.95E+ 05, and 2.79E+ 05, implying that alternative B is the inherently safer layout that can be fundamentally resistant to the potential Tank Pool Fire (TPF) domino effects. This work presents a cohesive set of theoretical solutions to preventing the spatial-temporal risks of the TPF domino effects with inherent safety concepts, which can be used to generate a fundamentally safer layout design scheme without adding extensive passive, active, and administrative protections.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
