This paper mainly introduces the importance and implementation steps of benchmarking management in petrochemical enterprises. Benchmarking management is an autonomous safety management method that identifies gaps and develops improvement plans by comparing with and analyzing peers or leading companies in the same industry. Petrochemical enterprises should focus on establishing a benchmarking system, developing standards, implementing benchmarking management, and analyzing and evaluating benchmarking results in order to carry out benchmarking management. Through the implementation of benchmarking management, petrochemical enterprises can continuously improve and enhance their performance, achieving the goal of autonomous safety management. Therefore, petrochemical enterprises should attach importance to benchmarking management and incorporate it into their management system to achieve sustainable development and enhance competitiveness.

Starting from multiple dimensions, this paper also puts forward specific suggestions to further optimize and improve the efficiency of enterprise safety training micro-courses so as to promote the continuous improvement of training in refining and chemical industry.

In petrochemical enterprises, with the introduction and development of safety production management concepts, the management of process technology changes has gradually shifted from disorderly development to advanced safety management systems. The risks associated with changes have been effectively controlled to a certain extent, but some problems still exist. Taking a certain petrochemical enterprise as an example, this paper analyzes the risks and existing problems in process technology changes, and proposes corresponding safety management measures and suggestions based on specific issues in practical implementation.

As higher standards for the safety and environmental protection of chemical enterprises has been put forward, Dushanzi Petrochemical Company, as a large-scale petrochemical base, has been consolidating the requirements of environmental protection and odor management and implementing the green and low-carbon management concepts in its production practice. According to the actual production operation, startup and shutdown, the environmental protection work will be implemented and connected to each production link so as to reduce the source of three wastes (waste gas, wastewater and solid waste) fundamentally. This paper analyzes the optimization measures taken to solve the environmental problems of the butadiene plant in actual production. And the application of various emission reduction and carbon reduction measures in the daily management and startup and shutdown processes has ensured the synergy among the plant's production, startup and shutdown operation, and environmental protection.

Downhole operations in oilfields have high safety risks during the construction process, and the degree of influence of various factors that lead to safety production accidents in downhole operations also varies.

The distribution network is an important component of the power system, and its operating status affects the stability and safety of the power system directly. However, due to the characteristics of the distribution network itself, its failure rate is relatively high and there are many types of faults, which has a great impact on the normal operation of the power grid. Therefore, studying the fault phenomena in the distribution network, identifying their causes, and adopting effective operation and maintenance management methods are of great significance for improving the operational efficiency and safety level of the distribution system.
