On March 5, a Shenghong Sierbang Petrochemical EC/DMC unit successfully produced high-grade products on its first attempt. With international leading technology and the company's own high-quality raw materials, the project produces high-end battery-grade EC/DMC (vinyl carbonate/dimethyl carbonate), further extending the new energy new material industry chain, and also marking another new breakthrough in Shenghong's "1+N" cluster innovation.
Seize the high point of innovation. New materials create a new market pattern.
EC/DMC is an important solvent for the manufacture of lithium battery "blood" - battery electrolyte. In recent years, the rapid development of China's new energy vehicle industry has driven a sharp increase in the demand for battery electrolyte solvents. For Lithium batteries using EC/DMC electrolyte solvents, while the safety performance is greatly improved, the charging and discharging performance at low temperature is also significantly improved, and they has a better cycle life. Battery-grade DMC has extremely high requirements for purity, usually requiring a purity of 99.99% or even over 99.999%. Such a high process threshold means only a few domestic enterprises that can produce battery-grade DMC, and there is a structural shortage of high-end products in the market. Relevant institutions predict that the global demand for battery-grade solvents will exceed 1.8 million tonnes in 2025, of which the demand for battery-grade solvents in China will reach more than 800,000 tonnes, with a compound growth rate of more than 35%.
Adhering to the idea of “frontier layout, hardcoretechnology, and cutting-edge product", Shenghong Petrochemical designs and builds EC/DMC devices based on international first-class standards, and innovates processes and catalytic technologies. All economic and technical indicators have reached the international advanced level. The project can produce 70,000 tonnes of battery-grade DMC and 38,000 tonnes of battery-grade EC per year. At the same time, it can produce 47,000 tonnes of EG (ethylene glycol) per year. The successful commissioning of the project can greatly reduce the localization gap in the high-end market. While extending the high-value-added industrial chain, it will further enrich the company's product matrix and improve the core competitiveness and risk-resistant operation ability of the enterprise.
Build a green negative carbon ecology and explore a new path for industrial transformation
At present, China's petrochemical industry is in a critical period of transformation and upgrade, and it is also a new starting point for the development of the high-end chemical new materials industry. Shenghong Petrochemical focuses on the new opportunities of the "Dual Carbon" Strategy and the new development pattern of "Double Cycle", gives full play to the innovation advantages of "Chain Master" enterprises, actively explores technological innovation and achievement Transformation From Low-Carbon, Zero-Carbon To Negative Carbon, And always takes the lead and demonstrates in promoting the new journey of Chinese-style modernization, and leads the green transformation of the industry.
Carbon negative, that is, to actively capture carbon dioxide for resource utilization through disruptive technological innovation. At present, Shenghong Petrochemical has innovatively built a green negative carbon industry chain of "carbon dioxide capture and utilization - green methanol - new energy materials". A 100,000 tonnes/year carbon dioxide-making green methanol unit has been successfully put into production, and the industry's first "Green Carbon Negative Industry Chain White Paper" has been released, providing a new green carbon negative model for the industry to refer to and learn from
As an expansion and extension of Shenghong's green negative carbon industry chain, the EC/DMC project undertakes the supply of high-quality raw materials for the enterprise's epoxy ethane (EO) device and carbon dioxide-making green methanol unit, and adopts industry-leading technology to actively recycle carbon dioxide in the exhaust gas of the EO device, directly consuming 70,000 tonnes of carbon dioxide/year, realizing the transformation of carbon dioxide into high-end new materials from the product end, reducing carbon emissions by "turning carbon into treasure" and extending the EO industry chain. Thus, it can further balance the existing EO production capacity of the enterprise, and achieve the harmony of social benefit, economic benefit and environmental benefit.
Focus on the high-end industrial chain and accelerate "1+N" cluster innovation
After years of development, Shenghong has built and completed the "1+N" innovative industry pattern based on the "core raw material platform" and the "new energy new material cluster". Focusing on the core of "1", we will continue to solve problems with "new", open the way with "new", continue to do long, deepen and refine the downstream "N" high-end new energy new materials industry chain, and strive to promote the development of "Full-chain, matrix-style, clustered" development.
The Shenghong Sierbang Petrochemical EC/DMC project is an important carrier for implementing the development idea of "improving the upstream and strengthening the downstream" of enterprises, while accelerating cluster innovation in the "1+N" mode. At present, Shenghong is making every effort to promote the new downstream energy storage project. By equipping downstream deep processing units with leading global scale, technology and energy consumption, it realizes efficient penetration and deep linking to the consumer market from the application stage. The commissioning of the EC/DMC unit can provide reliable raw materials supply for energy storage projects. It has significant integrated supporting research and development advantages, together with those of scale, cost and comprehensive development, which will inject vigorous vitality into the high-quality development of Shenghong industry.
At the same time, DMC, as a "new cornerstone" of organic synthesis, has excellent environmental protection performance and a variety of reaction properties. It has a wide range of applications in downstream renewable energy, 5G technology, integrated circuits, medicine, new additives and other cutting-edge fields. It will further help optimize Shenghong's product coverage in the high-end new materials market, and continue to give vitality to new technologies and new industries with rich and wider application scenarios.
Be advanced and strive for first-class. Shenghong Petrochemical will closely follow the green development pulse of the times, aim at national strategic emerging industries, have the courage to innovate and practice, rely on the development layout of the whole industry chain, accelerate the deep integration of technological and industrial innovation, make every effort to build a world-class new energy and new materials industry cluster, and strive to write the "Shenghong Answer Paper" of high-quality development in promoting the "strong, rich, beautiful and high" in new Jiangsu’s modernization practice.
