The \"green, low-carbon intelligent factory for coal-based ethylene glycol\" developed with the active involvement of Zhongkong Technology by Yulin Chemical has been recognized as an \"excellent-level intelligent factory.\" 2025-12-16 13:17 · Tonghuashun Finance. The \"green, low-carbon intelligent factory for coal-based ethylene glycol\" developed with the active involvement of Zhongkong Technology by Yulin Chemical has been recognized as an \"excellent-level intelligent factory.\" ### Introduction Recently, the \"green, low-carbon intelligent factory for coal-based ethylene glycol\" owned by Shaanxi Coal Group Yulin Chemical Co., Ltd. (hereinafter referred to as \"Yulin Chemical\") was designated as an \"excellent-level intelligent factory\" by the Ministry of Industry and Information Technology and other authorities. It is the only coal chemical enterprise under provincial ownership in Shaanxi Province to receive this recognition, marking Yulin Chemical’s entry into the top tier of intelligent manufacturing enterprises in China. As an \"upgraded version\" of intelligent manufacturing, an elite-level smart factory requires efficient coordination across the entire value chain, achieving industry-leading standards in areas such as intelligent production, data integration, and AI applications. In the list of projects announced by the Ministry of Industry and Information Technology for 2025, a total of 274 enterprises across the country were rated as excellent smart factories. As a core partner involved in the project’s journey toward intelligence from its inception, Zhongkong Technology has witnessed and been deeply involved in the process of creating this outstanding achievement. Yulin Chemical’s achievements in intelligence are the result of its systematic planning and consistent investment. In recent years, relying on its own unified industrial Internet platform, the company has established a data chain that covers the entire process from raw material intake to product delivery, thereby enabling intelligent coordinated management across various stages. By using advanced control algorithms to optimize process parameters in real time, the factory’s production efficiency increased by 5.37%, with the level of automated control rising to over 95%. It also set an industry record by achieving \"black-screen operation\" for the 180 Project 2 series DMO distillation units for more than 155 days, serving as a replicable and scalable example for the intelligent development of the coal chemical industry
Behind this series of outstanding achievements lies years of close collaboration and mutual support between Zhongkong Technology and Yulin Chemical. The cooperation between the two parties began in 2020. For one of the world’s largest single-unit coal-to-ethylene glycol projects with an annual capacity of 1.8 million tons, Zhongkong Technology provided a comprehensive solution covering core control, equipment management, energy optimization, and safety interlocks, thereby establishing an integrated data intelligence system for production, equipment, energy, and safety. This system not only enables real-time monitoring of the operating status of key equipment and predictive maintenance, but also provides continuous support for energy savings and reduced consumption in the facility through process optimization models. The successful implementation of the first-phase project provided a solid data foundation and management capabilities for Yulin Chemical’s subsequent intelligent upgrades, and it also helped the company win the title of \"2023 **Smart Manufacturing Demonstration Factory\". Building on the successful trust and significant results achieved in the first-phase project, the cooperation between the two parties saw a more strategic deepening in 2025. In June this year, Zhongkong Technology successfully won the bid for Phase 2 of Yulin Chemical’s \"15 million tons per year demonstration project for clean and efficient conversion of coal based on different quality levels.\" This project is a landmark initiative in the field of clean coal conversion worldwide. It not only represents the market’s recognition of Zhongkong’s comprehensive capabilities in large-scale, complex projects but also signifies that the partnership between the two parties has entered a new phase of collaborative innovation. To date, the two parties have successfully signed the framework agreement and held a project kickoff meeting; all tasks are progressing as planned, with full construction set to begin in 2026. This phase will involve integrating a factory operating system with an industrial AI infrastructure to support N intelligent application scenarios. The goal is to help customers establish an intelligent closed-loop system for \"identification-evaluation-decision-making-execution\" across processes ranging from coal pyrolysis and chemical synthesis to product deep processing, thereby achieving deep coordination and dynamic optimization in production operations. This will enable Yulin Chemical to turn its second-phase project into a model of next-generation smart factories with enhanced capabilities in self-perception, self-optimization, and self-decision-making. Looking to the future, Zhongkong Technology is making every effort to drive the technological evolution from smart factories to Autonomous Operation Plants (AOP), thereby achieving a high level of autonomous operation in process industries – with intelligent internal control and unmanned external operations, similar to advanced autonomous driving systems. We expect that by enabling customers to achieve unmanned operation of key units, optimizing energy efficiency across the entire plant, and facilitating intelligent coordination within the supply chain, it will be possible to achieve \"safe production, improved product quality, reduced energy and material consumption, cost reduction and efficiency improvement, as well as enhanced corporate competitiveness.\" Central control technologies will continue to increase their investment in research and development, striving to implement the advanced concepts and technologies of AOP in industry leaders such as Yulin Chemical, thereby generating trillions in additional value for the industry.
