某化工厂危险化学品重大危险源辨识与分级研究

本科论文AbstractFor chemical enterprises,the identification and classification of major hazard sources isextremely important.Chemical plants store a large number of hazardous chemicals,once theamount of storage beyond the critical amount will become a hazard source,if the hazardsource is not well controlled will likely lead to major accidents.Every year,there are manyhorrendous accidents around the world caused by dangerous chemicals,the tragicconsequences of which are heart-wrenching.So in order not to happen all this,in order toenterprises can be safe and orderly production,factories and enterprises can run smoothly.We must do a good job in the identification and classification of major hazard sources.So I'mwriting this paper The hazardous chemicals in a chemical plant are studied in the center ofidentification of major hazard sources and classification of hazard sources.At the beginning of the thesis,the development status of identification and classificationof major hazard sources at home and abroad is introduced.Both domestic and foreigncountries attach great importance to hazard source identification and classification research,and also issued a series of laws and regulations to improve the major hazard sourceidentification and classification of the research topic.In this paper,we introduce a lot of theoretical knowledge about the identification andclassification of major hazard sources,and the relevant theoretical knowledge of safetyevaluation.Then the paper takes a chemical plant as an example,combined with the investigation ofthe chemical plant,the chemical plant production workshop,storage area,hazardouschemicals warehouse in the identification and classification of major hazardous sources.Then the paper takes a chemical plant as an example,combined with the investigation ofthe chemical plant,the major hazard identification and classification of chemical plant.Then,the paper carries on the safety evaluation to the system identification further,this paper usestwo evaluation methods,the pre-risk analysis method and the accident tree method.According to the pre-risk analysis method and the evaluation results of the accident treemethod,the safety hidden danger in the system is analyzed,and the risk factors are easy tocause the accident.
