In 2023, the company implemented energy-saving and high-efficiency rectifier transformers, permanent magnet synchronous motors, circulating water cooling tower turbines, energy-saving and high-efficiency circulating water pumps and other equipment energy efficiency improvement transformation, which can save 5.8 million kilowatt-hours of electricity and reduce carbon dioxide emissions by about 3,307 tons per year.
Safety and environmental protection improvement:
1. Solidly promote process safety management and further improve intrinsic safety
(1) During the overhaul in November 2023, the company carried out safety instrument transformation for the first-class major hazard sources (liquid chlorine and chloromethane storage tank units) in accordance with the requirements of the national three-year action plan, Order No. 30 of major hazard sources, and 20 major hazard judgment standards, especially those involving high-risk media such as chlorine and liquefied hydrocarbons. In the process of transformation, the hazardous media in each storage tank were emptied, purged and replaced, and the operation was carried out after passing the analysis, and more than 70 SIS and DCS emergency shut-off valves were added to the inlet and outlet of the storage tank, and the intrinsic safety automation transformation and commissioning were successfully completed.
(2) Carry out actions to improve the automatic control rate of old equipment and instruments. The company's methane chloride plant has been put into production for more than 15 years, and in 2023, it will focus on upgrading the automatic control instrument of the distillation post of the device, improving the accuracy of the control valve, improving the control effect, and the automatic control rate will reach more than 92%, further improving the safety production stability of the process device.
(3) The new project adheres to the strategy of "mechanized substitution, automation and reduction". In 2023, the company's new project 803 high-quality hydrogen peroxide (hydrogen peroxide) purification workshop passed the on-site audit of Suzhou Bureau of Industry and Information Technology. Up to now, the company's three production units (styrene propylene sizing agent, 803, 709 chloromethane workshop) have passed the "intelligent workshop" audit, the production process adopts the whole process of automatic control, and the site is inspected by one person per shift, and the company will apply for an intelligent factory in 2024.
2. Digital intelligence empowerment to build compliance management for special operations
