Safety evaluation of chemical production based on AHP-fuzzy comprehensive evaluation method

Abstract

In order to prevent fire and explosion accidents in the production process of chemical companies and ensure the production safety of chemical companies, taking the styrene production process of a chemical company as an example, according to the production characteristics of chemical companies and the hazardous factors in production, combined with industry expert opinions, 17 safety evaluation indexes affecting the safety in production of chemical enterprises are analyzed and summarized from the aspects of human, machine, material, environment and management, the second level safety evaluation index system is established, and AHP-fuzzy comprehensive evaluation method is used for production. The safety evaluation of the process showed that the production status of the chemical enterprise was relatively dangerous. The danger mainly came from management and materials. The enterprise did a good job in terms of human, machin and environment. This evaluation method can objectively and accurately evaluate the risk of chemical production, help companies find the key prevention direction of accidents, strengthen safety supervision, and prevent the occurrence of fire and explosion accidents. It provides a reference for the application of AHP-fuzzy comprehensive evaluation method in chemical engineering evaluation in the future.
