The study aims to analyze the burst characteristics and examine the variations in TR behavior under specific conditions, with the goal of improving early warning and protection against LIB TR incidents. The research findings demonstrate that mechanical nail penetration can rapidly trigger TR, resulting in the highest temperature 522.3°C within 51.9 s, and the fastest is 20 s. In the case of LIB modules, a secondary temperature rise occurs, exhibiting an increased rate of up to 77%. Notably, when the battery bulges, there is a release of high‐temperature two‐phase heat flow accompanied by a significant discharge of combustible gases. This escalation increases the risk of further explosions. Moreover, the study observes repeated spray fires and the generation of a considerable amount of smoke. Additionally, the study highlights the role of sudden rise in temperature and the release of H2 as early indicators of TR. These findings provide valuable theoretical insights into the characteristics and risks of square soft LIBs, enhance safety measures, and contribute to the development of early warning systems for LIBs.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"209 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140942473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most research on the optimized layout of leakage monitoring has focused only on point gas detectors. In this paper, an optimization model for a hybrid layout of point and open‐path gas detectors was proposed considering the cost–benefit ratio and detection time. As the measured value of an open‐path gas detector is an integral concentration, a monitor line in the simulation was calculated via the approximate rectangle method. The results showed that the use of a multiobjective gas detector layout considering the cost–benefit ratio and an improved non‐dominated sorting genetic algorithm (NSGA‐II) could optimize the layout of hybrid detectors. The hybrid layout was analyzed in a case study of process facilities at a natural gas station. As the number of detectors increased (safety investment), the proportion of open‐path gas detectors increased, improving both leakage monitoring performance and the cost–benefit ratio. Additionally, the layout of the point gas detectors was analyzed. A comparison of objective function values for detection time showed the superiority of the hybrid layout in our research.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"37 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of experiments were conducted in a shock tube on 15 specimens (walls and doors) constructed according to the design recommendations in KGS FP112. The design elements of 12 walls are the materials, the thickness, and the holder positions, while the 3 doors were made of steel plates with different types and structures. The shock tube tester used in dividual specimens were exposed to blast overpressure of 0.11 or 0.17 MPa. From the acquired data and visual inspection, we conclude that the current designs of blast mitigation for high‐pressure gas‐storage facilities in KGS FP112 are acceptable for an accidental overpressure of up to 0.17 MPa, provided that both sides of the wall are supported by auxiliary structures such as adjacent barriers. Furthermore, the walls and doors as in KGS FP112 show comparable protection performances. Nevertheless, recommendations for doors are as follows: it may require additional latches and remain closed, and when designing the facility, the doorway may be located in a place with less possibility of direct exposure to the overpressure.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140628368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to conventional hazard methods, system theoretic process analysis (STPA) can analyze the hazards in system control processes from the perspective of interactions among the system components. Theoretically, this method offers advantages that are better suited for modern production systems. However, as of now, the integration between STPA and process industrial production systems is still lacking. To address this issue, this study improved the original STPA method. First, we propose the “5 flows” concept for the process industrial cyber‐physical systems. The systems are described using multilevel flow modeling (MFM). This leads to the development of the MSTPA method, which is specifically designed to analyze the cyber‐physical hazards in process industrial production systems. Subsequently, the cyber‐physical hazards of a fluidized‐bed catalytic cracking unit are analyzed in detail using the MSTPA method as an example. The results show that MSTPA can identify cyber‐physical hazards in multiple dimensions. It is proved that, compared with the original STPA and traditional hazard methods, the MSTPA method can better identify cyber‐physical hazards in process industrial production systems.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"39 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140564701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
