Problems solved by technology
[0004] However, in the existing research, the error of the interpolation method is large due to the lack of index classification, and it cannot reflect the dangerous trend of process parameters such as temperature and pressure. 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 the existing assessment methods fail to effectively integrate expert experience and the continuous risk of temperature and pressure, this patent proposes a continuous inherent risk assessment method for process risk, which will more accurately characterize the hazardous characteristics of chemical processes and improve Effectively guide enterprises to carry out hierarchical management and control

Embodiment Construction
[0040] A continuous inherent risk assessment method for process risk is based on a logistic curve (S-curve) and experts optimize and adjust the existing risk classification standards to realize the assessment of the inherent risk of process equipment.
[0041] The inherent risk assessment method specifically includes:
[0042] The first step is to select a company and choose a suitable chemical company for risk assessment, so as to avoid waste of manpower and material resources;
[0043] The second step is to select the process unit, and select the process unit in the enterprise that needs to evaluate the inherent risk. This inherent risk assessment method is applicable to chemical process equipment, but not applicable to storage tank farms and warehouses;
[0044] The third step is the substance intrinsic risk assessment M1;
[0045] The fourth step is the risk assessment M2 of special substances;
[0046] The fifth step, substance toxicity T assessment;
[0047] The sixth...

The invention provides a method for assessing the inherent risk of continuous process risk, which optimizes and adjusts based on the S-curve and expert experience, and realizes the evaluation of the inherent risk of the process device. Compared with fuzzy evaluation, Shepand interpolation and S-curve, the present invention combines expert experience and logistic curve (S-curve) and further optimizes the index value curve, and the obtained continuous inherent risk assessment method of process risk will be more accurate. Accurately characterize the hazardous characteristics of chemical processes, and more effectively guide enterprises to carry out hierarchical management and control.
Description
technical field [0001] The invention belongs to the technical field of petrochemical safety production risk assessment, and in particular relates to a method for assessing the inherent risk degree of continuous process risk. 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 mo...
