石油萘裝置事故致因因素辨識與風(fēng)險評價
[Abstract]:Petroleum naphthalene unit is one of the typical units in petrochemical industry, which has the common dangerous characteristics of fire, explosion and poisoning in petrochemical plant. It is important to study the accident factors and risk characteristics of the plant to identify the risk state of the production plant and to improve the effectiveness of emergency management. It can provide a basis for the managers and decision makers to make a quick judgment and take corresponding measures. In this paper, the accident cause factors of petroleum naphthalene unit are identified, the process risk of petroleum naphthalene unit is evaluated by Dow's method and ICI Mond method, and the difference between the two methods in evaluation is compared. The results show that the ICI method is more suitable for the evaluation of the plant and can reflect the risk state of the plant more comprehensively. Based on the environmental risk assessment, the PBT method is used to analyze and screen the risky substances of the plant, and the environmental risk assessment and comparison between the storage tank area and the production unit area are carried out, respectively. The results show that the risk of the storage tank area is greater than that of the production unit area. This paper establishes an index system to evaluate the effectiveness of emergency management, uses AHP to determine the weight, and evaluates the effectiveness of the existing HSE system. Finally, the effect of LDAR technology on reducing VOC (VOCs) emission and accident risk is analyzed.
