On July 10, Wang Jingli, deputy manager of the Public Utilities Department at Dushanzi Petrochemical, activated the AI-based temperature prediction model that had been put into use at the end of June, and saw clearly that the temperature of the cooling water remained stable within the optimal range, enabling precise management that ensured \"not a single drop of water was wasted.\" In the first half of this year, the water consumption of Duhu Petrochemical’s ethylene plant remained the lowest among the refining and chemical integration enterprises within the group company.   Led by technological innovation, Duhu Petrochemical advances its green and low-carbon transformation at high standards, continuously strengthens environmental protection, and aims to create a green factory free from odors, thus pursuing a path of high-quality development that achieves benefits for both the economy and the environment. On June 28, at the 2025 Energy Industry Ecology Forum organized by the China Enterprise Reform and Development Research Association, Dushihua’s case titled “High-Standard ‘Carbon’ Pathways: Creating an Ecosystem for High-Quality Development” was selected as an outstanding example of efforts to achieve the ‘dual carbon’ goals.   In 2021, Duhu Petrochemical took advantage of its expertise in combined professional skills and information technology to independently develop an energy management platform using the MES2.0 system, expanding its scope of application. It implemented practices for quantitative energy management and established monitoring systems for energy balance, energy consumption, fuel costs, online analysis of monthly energy reports, and carbon emissions; these systems covered more than 1,200 areas where energy losses could occur, thereby creating a closed-loop energy management system across the entire process chain.   Wen Bin, the senior manager in charge of system energy at Sinopec’s Production and Operation Department, said, “Through this platform, it is possible to accurately monitor trends in energy consumption, identify areas where energy use is unreasonable or unscientific, explore opportunities for energy savings, and achieve sustained energy conservation over the long term.” ”   In 2023, Duhu Petrochemical built an intelligent water management platform to carry out intelligent management of the entire plant’s water system, enabling classified use of water quality, recycling, and reduction of losses, as well as automatic measurement and planned management of wastewater discharge.   To ensure the continuous and stable operation of the sterilization facilities, Duhu Petrochemical conducts two analyses of the residual chlorine in the circulating water daily, and adjusts the dosage of chemicals accordingly based on the results of these analyses. It also regularly evaluates and analyzes energy consumption, thereby refining the management of the circulating water system to maintain good water quality. After years of technical upgrades, the pollutants treated by Dushanzi Petrochemical have reached ultra-low emission levels, meeting the requirements set for enterprises in key industries classified as Grade A in terms of performance.   Going forward, Duhu Petrochemical will aim to promote green and low-carbon development. It will make concrete efforts in areas such as green products and services, green production and processes, as well as green culture and responsibility, in order to drive sustainable green and low-carbon transformation, and continue to contribute its own solutions to the industry’s green transition.
