Providing a \"China Coal Solution\" for the high-quality development of the coal chemical industry. Author/Source: Sinochem News Network. Date: November 15, 2022. Clicks: 28. As a central state-owned enterprise in the energy and chemical sector, China Coal Shaanxi Yulin Energy Chemical Co., Ltd. aims to unleash the \"primary driving force,\" activate the \"primary resources,\" and ignite the \"primary momentum\" by accelerating innovation in science and technology, thereby achieving a high level of self-reliance and strength in this field. This approach is intended to make positive contributions to promoting the advanced, diversified, and low-carbon development of the coal chemical industry. As the first large-scale modern coal chemical enterprise established by China National Coal Group in Shaanxi, since the * era, China National Coal Group Shaanxi Company has earnestly implemented the innovation-driven development strategy. By focusing on integrated technological innovation, high-end technical equipment, and digitalization of smart factories, it has built a complete industrial chain that transforms coal into methanol and then into polyolefin products, turning what was once \"black\" into \"white\" products. It was the first in the industry to pursue digital transformation, actively developing compact industrial chains, value chains, and safety frameworks. In the process of creating a modern coal chemical industry characterized by multiple energy sources working together and featuring green and low-carbon principles, it has developed its own unique approaches and models. China Coal Shaanxi Company emphasizes both the renovation of energy-saving and carbon-reduction projects and their management, continuously improving the energy-saving and carbon-reduction performance of its production facilities, and striving to become a leader in energy conservation and emission reduction within the industry. Since the 1.8 million tons per year methanol plant and the 600,000 tons per year polyolefin plant came online in July 2014, various energy-saving and emission-reduction measures such as coal slurry concentration and comprehensive utilization of gasification residues have been implemented, resulting in an annual savings of 430,000 tons of standard coal – achieving significant results. By continuously working on reducing carbon at the source, during production processes, and at the point of use, we explore the management of carbon throughout the entire life cycle of coal-based olefin production. In December 2021, the \"Carbon Balance Report of the Chemical Division of China Coal Shaanxi Company\" was completed, establishing a carbon footprint system for the entire life cycle. At the same time, digital transformation is pursued comprehensively to achieve more precise energy management. Regularly carry out energy efficiency benchmarking to continuously reduce the energy consumption of the equipment. Our company’s Phase II chemical project, as a pilot demonstration project for carbon assessment in China’s coal chemical industry, has attracted attention within the sector. For this project, we have some new ideas in the area of green and low-carbon development as the next step. Although the second phase of the chemical project will still focus on the production of olefins from coal-based methanol, in line with the green and low-carbon development goals set forth*, we need to carry out comprehensive optimization of the project throughout its life cycle. By fostering strong \"core strengths\", we can achieve a new model of \"using coal, leveraging coal, and going beyond coal\", thereby promoting the green, low-carbon, clean, and efficient utilization of coal. For example, coal-fired boilers should be phased out, the proportion of electrification should be increased significantly, and drive equipment should be switched from steam-driven to electrically driven, thereby reducing coal consumption to zero ; New photovoltaic and wind power projects will be established utilizing the facilities of the chemical subsidiary and its associated Dahaize mine area; part of this ‘green electricity’ will be used to replace external power supplies ; Actively explore the core technologies of \"liquid sunlight,\" using \"green hydrogen\" and \"green oxygen\" produced by electrolyzing water with renewable energy as sources of hydrogen and oxygen for coal chemical industries ; Capturing and recovering high-purity carbon dioxide generated by chemical plants as raw materials for chemical production not only significantly reduces coal usage and carbon emissions but also increases the output of chemical products. At the same time, coal chemical plant exhaust gases are utilized comprehensively to implement a 1 million tons per year carbon dioxide utilization project, thereby creating a closed carbon loop that covers treatment from the source to recycling.
