Recently, the list of companies that led in energy efficiency within key energy-consuming industries for 2022, as well as the list of companies and industrial parks that excelled in water efficiency for the same year, were published. Among them, six petrochemical companies – Hengli Petrochemical (Dalian) Refining & Chemical Co., Ltd., Sinopec Qingdao Refining & Chemical Co., Ltd., CNPC Zhenhai Refining & Chemical Branch, Binhua Group Co., Ltd., Wanhua Chemical (Ningbo) Chlor-alkali Co., Ltd., and Qingdao Gulf Chemical Co., Ltd. – made it onto both lists. The list of energy efficiency leaders in key energy-consuming industries for 2022 was jointly released by the Ministry of Industry and Information Technology, the **National Development and Reform Commission, and the State Administration for Market Regulation. The list covers industries such as crude oil processing, ethylene, methanol, caustic soda, soda ash, and tires; a total of 43 enterprises are included on it, 27 of which are chemical companies, including Sinochem Quanzhou Petrochemical Co., Ltd., Henan Xinlianxin Chemical Industry Group Co., Ltd., Fujian Hesheng Gas Co., Ltd., Shandong Lianmeng Chemical Co., Ltd., and others. To fully leverage the leading role of energy efficiency pioneers, the Department of Energy Conservation and Comprehensive Utilization under the Ministry of Industry and Information Technology provided a detailed explanation of the typical practices and advanced experiences of such enterprises. For example, in the crude oil processing industry, Sinopec Qingdao Refining & Chemical Co., Ltd., one of the selected companies, improved its comprehensive energy consumption per unit of product by 8.86% in 2021 compared to the advanced standard values, through measures such as installing waste heat recovery systems, carrying out energy-saving upgrades to the flow area of turbines, and setting up 1.4-megawatt photovoltaic power generation systems. In the soda ash industry, the selected company, Tangshan Sanyou Chemical Co., Ltd., achieved a reduction in the comprehensive energy consumption per unit of lightweight soda ash produced by the ammonia-soda process by 8.51% compared to the benchmark level in 2021, and a reduction of 16.74% in the comprehensive energy consumption per unit of heavy soda ash compared to that benchmark level. This was accomplished through methods such as recycling waste calcium carbide slag and nitrogen-oxygen enriched exhaust gases, utilizing oxygen-enriched air for combustion, as well as adopting advanced intelligent control systems for lime kilns and control systems for the calcination process of light ash. In addition, the Ministry of Industry and Information Technology, the Ministry of Water Resources, the **National Development and Reform Commission, and others jointly released the list of key water-consuming enterprises and water-efficiency leaders among industrial parks for 2022. This list identifies 74 water efficiency leaders and parks that possess a leading, exemplary, and exemplary driving effect. Among them, more than 20 chemical companies, including Sinopec Great Wall Energy Chemical (Ningxia) Co., Ltd., Jinneng Holding Equipment Manufacturing Group Huayu Energy Chemical Shanxi Co., Ltd., and Luxi Chemical Group Co., Ltd., were included on this list. It is worth noting that Hengli Petrochemical (Dalian) Refining & Chemical Co., Ltd. leads in multiple niche industries. For example, in the petroleum refining industry, the company achieves a water reuse rate of 98.79% ； In the coal-to-methanol segment of the modern coal chemical industry, the company achieves a water reuse rate of 99.94%.
