Abstract
Chemical industry is the pillar industry of the fast development of national economy. The risk of chemical process is an important part of its industry’s development. In this paper, according to the determined influencing factors based on the chemical process of intrinsic safety and the selection principle of evaluation indexes, chemical process risk evaluation index system based on intrinsic safety is established. Combined with several years' monitoring data and using hierarchical analysis model to calculate the weight coefficient of each evaluation index, the chemical process risk based on intrinsic safety is divided into four levels, such as Level I low risk, Level II medium risk, Level III high risk, Level IV highest risk. By means of the monitoring data to carry on its scoring, according to membership function to obtain the fuzzy comprehensive evaluation matrix, chemical process risk evaluation model based on intrinsic safety is then established, taking a certain chemical process for example to carry on a simulation calculation. Its combination is in accordance with the local situation. This method is professional, reasonable and scientific, which provides a theoretical basis for the chemical process risk evaluation.
