Problems solved by technology
[0004] However, in the existing research, the error of the interpolation method is relatively large due to the lack of index classification, which cannot reflect the original dangerous trend of the substance. Although the S-shaped curve overcomes the above difficulties, it lacks the correction of expert experience
[0005] In order to further solve the problem that existing assessment methods fail to effectively integrate expert experience and reflect the continuous risk of substances, this application proposes a continuous inherent risk assessment method for material hazards, which will more accurately characterize the hazardous characteristics of chemical processes and be more effective. Guide enterprises to carry out hierarchical management and control

Embodiment Construction
[0055] The present invention provides a method for assessing the inherent risk of material hazards, which includes:
[0056] The first step is to select a company, because the method is applicable to chemical companies, so choose a suitable company for risk assessment to avoid waste of manpower and material resources;
[0057] The second step is to select a process unit. The inherent risk assessment method provided by the present invention is applicable to chemical process equipment, but not applicable to tank farms and warehouses;
[0058] The third step is to calculate the flash point risk F of the substance;
[0059] The fourth step is to calculate the material explosion limit risk E;
[0060] The fifth step is to calculate the toxicity risk T of the substance;
[0061] The sixth step is to calculate the quantity risk I of the substance;
[0062] The seventh step is to calculate the material coefficient M: M=F+E+T;
[0063] The eighth step is to calculate the general pr...

The invention provides a substance hazard continuity inherence risk factor assessment method. Expert experiences and an S-type curve are combined and an index value curve is further optimized. Through the method, a chemical process hazard characteristic is accurately represented and an enterprise can be effectively guided to carry out grading control.
Description
technical field [0001] The invention belongs to the technical field of petrochemical safety production, and in particular relates to a method for assessing the inherent risk degree of continuous material danger. Background technique [0002] The petrochemical industry is the pillar industry of the national economy. With the rapid development of my country's economy and the deepening of the industrialization process, the large-scale and complex chemical production equipment makes the possibility of major accidents more and more serious, and the consequences are more serious. On November 13, 2005, the huge explosion accident of CNPC Jilin double benzene plant caused 8 deaths, more than 10,000 people were evacuated, and caused serious pollution to the downstream and foreign rivers; on August 26, 2008, Guangxi Yizhou Guangwei Chemical Co., Ltd. An explosion accident occurred in the organic workshop of the company, killing 20 people, and the direct economy reached more than 75 mi...
