The method combines probabilistic prediction and consequence assessment: the former is predicted by Bayesian networks derived from bow‐tie mapping, in which the conditional probabilities are determined by analytic hierarchy process, the latter is calculated based on numerical simulation of accident consequences and Probit probability model. The application results show that the method can be used for quantitative risk assessment of liquid ammonia storage tank, and the Bayesian network model is efficient and stable, which can realize risk prediction, accident causes analysis and risk mitigation analysis. Human errors during production or maintenance and corrosion are the main causes of liquid ammonia leakage. Toxicity has the greatest effect on the risk of liquid ammonia tanks. Risk mitigation measures can significantly reduce individual risk and societal risk. The obtained results provide meaningful guidance for the prevention and risk mitigation strategies of liquid ammonia leakage accidents, so as to improve the safety level of liquid ammonia during storage.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"344 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138553505","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}

Unfortunately, the volume of gas leaking through the SDV is sometimes beyond the predetermined criteria. Therefore, a quantitative risk assessment is needed by conducting cost–benefit analysis (CBA). This is the methodology of this study. First, we carry out a frequency analysis to calculate the frequency of release from an isolatable section using an estimate of the release frequency, event tree analysis, and escalation from consequence modeling. Second, we study the consequences of modeling. Third, we carry out risk analysis and evaluation. Fourth, we do CBA calculation. Fifth, we consider the other perspectives. The results of this study can predict the possibility of riser SDV leakage in offshore facilities during the aging period and optimize operating and investment costs while maintaining safety to reduce the possibility of fire explosions. It poses a challenge because of the complexity of operational systems involving multiple potential contributors and multiple safety measures. The study results show that the probability of fire prediction at SDV with processing facilities increases from 8.10 × 10−09 to 7.93 × 10−05 for the worst case scenario. Case studies show that application of the CBA model can be used to optimize the allocation of safety investments.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":" 18","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138494091","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}

The effects of the obstacles parallel to the vent on the structural response of the container during the explosion venting were investigated. The internal overpressure and acceleration of the vessel wall were captured by acceleration and pressure sensors, respectively. The time–frequency distributions of pressure and acceleration were obtained by a Short-Time Fast Fourier Transform. The effects of obstacles on the dynamic structure response were studied by analyzing the internal overpressure, vibration acceleration, and high-speed videos. With the increase of obstacles, the maximum overpressure and vessel vibration increased, and the maximum overpressure and maximum vibration acceleration appeared earlier. The vibration signals had two dominant frequencies, 300-600 Hz and 900-1200 Hz. The low-frequency vibration (300–600 Hz) was induced by acoustic oscillation of the internal pressure. The high-frequency vibration (900–1200 Hz) was a container resonance triggered by the coupling of the flame and the acoustic wave. As VBR increased, the duration of high-frequency oscillations decreased gradually; the increase of obstacles would weaken the high-frequency structural response of the container. The results can guide the design of hydrogen explosion protection and mitigation measures.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"75 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138504705","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}

Firstly, the authors gathered 1134 accident investigation reports and employed the “5W1H” analysis method to extract six types of accident attributes: time, location, cause category, activity, building type, and accident type. Subsequently, a word cloud map was employed to identify the primary direct causes, and the correlation characteristics among the four cause categories were analyzed. Finally, a heterogeneous correlation network of building construction accident attributes was constructed using Gephi software. Topological parameters were introduced to analyze the relationships among the six accident attributes. The results indicate that a complex network can effectively analyze the interplay among various construction accident attributes, thus revealing the correlation laws and accident characteristics between various accident attributes. The set of key nodes is represented as {F1, F2, B2, B17, F3, B4, B16, B5, F4, B15, D20}. Thirteen highly correlated sets of accident attributes were identified, highlighting the need for collaborative accident prevention strategies. These findings have the potential to visually present accident knowledge, offering innovative insights for the analysis of building construction accidents.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"75 2","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138504704","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}

As a result, unintential release of a large amount of anhydrous ammonia could result from an accident during transportation. The aim of this paper is to provide a better understanding of the evaporation of anhydrous ammonia from porous media. In our investigation, laboratory-scale concrete coupons were used as a surrogate for a larger concrete pad that could be present in an event involving an unintentional release of liquid anhydrous ammonia. Concrete coupons sized 5 cm × 5 cm × 1.9 cm were saturated in liquid anhydrous ammonia, and measurements of the subsequent evaporation from the coupons were made in an environmental chamber. The ambient air temperature within the chamber varied from 5 to 45°C, and the relative humidity varied from 5% to 75%. Mass-difference calculation and Berthelot's reaction were used to determine the average evaporation rate from a concrete coupon across all trials, which was found to be 6.5 ± 1.9 mg/s. To validate these evaporation rates, the remaining ammonia in the concrete coupon was measured for each trial. We found that the time-integrated calculated evaporation rates correlated well with the total mass of ammonia that was lost from the coupons. In addition, it was found that ambient air temperature and relative humidity had little influence on anhydrous ammonia evaporation from the concrete coupons.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"76 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138504699","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 the process of oil spill weathering on the sea, the oil is potentially mixed with water to form oil–water emulsification. The in situ burning is a low‐pollution and high‐efficiency method to eliminate the spilled oil. Meanwhile, as an alternative fuel, the emulsified diesel fuel has the advantage of energy saving and emission reduction. The combustion behaviors of pool fire of diesel fuel–water emulsifications are experimentally studied using three circular fuel reservoirs (10, 15, 20 cm) and five mass proportions of water (0%, 5%, 10%, 15%, 20%). The unsteady combustion process of emulsified diesel fuel is appreciated based on combustion phenomenon, mass burning rate, and flame length. The effects of pool diameter, ratio of water content, and initial fuel thickness on burning rate and flame length are revealed. The primary heat transfer mode in controlling the combustion behavior is explored according to the coupling factors of physical boundary of fuel reservoir, flame, and wall temperatures. This work is of great significance for understanding the combustion behavior of oil spill on the sea and optimizing the removal scheme of oil spill pollutants.","PeriodicalId":20680,"journal":{"name":"Process Safety Progress","volume":"28 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135681666","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}
