The Construction Of Safety Assessment System For Gasoline Tank Farm Based On Process Safety Management

The frequent accidents in the tank area show that there are obvious deficiencies in the technical and safety management of China's petrochemical enterprises in recent years.The gasoline tank farm mainly store up gasoline.Because the process in the tank area is simple and the production continuity is weak,the safety management of the production equipment is more important than gasoline tank area.the safety standardization and HSE management system are mostly in the domestic gasoline tank area,but the safety management mode is relatively simple,and the target is weak,and the risk identification,risk analysis and loss control are short.In view of the above problems,a safety assessment system of gasoline tank farm based on process safety management is constructed in this paper.Through the analysis of the occupational health and safety assessment system(OHSAS),the international security rating system(ISRS),the risk based management(RBI)and the safety standardization,understand the advantages and disadvantages of the assessment tools,and the differences in the application areas limit their applicability.In the selection of safety assessment elements,the method of combining the statistical analysis of accident reasons with the analysis of the factor weight of safety assessment is adopted in the selection of safety assessment elements.Compared with the traditional selection method,this method can avoid the arbitrariness and subjectivity of the assessment elements,and can also ensure the comprehensiveness of the assessment elements.This method is used to determine the factors affecting the safety assessment of tank farm.According to the importance grade,the assessment elements are divided into 12 primary factors and 37 the secondary elements.By using the analytic hierarchy process(AHP)to construct the judgment matrix of the assessment elements,after the consistency check,calculate the weight ratio of the safety assessment elements,and the construction of the safety assessment element system of the tank area is basically completed.According to China's safety standardization and petrochemical industry related standards and laws and regulations,designing and quantify the secondary factors,the maturity model is introduced to grade the evaluation results,and the safety assessment system of gasoline tank based on process safety management is completed.The whole assessment process improves the efficiency and objectivity of the evaluation process.In order to prove the applicability and effectiveness of the system in the petrol tank farm,the engineering case is applied to the completed safety assessment system.According to the results of the evaluation,it puts forward some suggestions on the deficiency of the tank area,compares the evaluation results with the results of domestic tank area assessment,finds out the gap and improves the space,and for the safety management of the tank farm,clearly defining the next step.
