Over the past decade, great progress has been made in chemical engineering and technology; truly a testament to the prosperity and strength of China! This post serves as an opening invitation for everyone to participate in the discussion—the more participants, the livelier the conversation will be. With your involvement, this community becomes even more vibrant! This is a continuously updated compilation post on “Ten Years of Great Development in Chemical Engineering Equipment”; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html. Let us enhance our awareness of quality and strive for high-quality development. ----------------------------------------- In May 2014, the Sinopec project aimed at localizing key equipment—the “Intelligent Control System for Million-Ton-Scale Oil Refineries”—was successfully tested and demonstrated at Changling Refining & Chemical Complex. This marked the end of China’s reliance on foreign control systems for its million-ton-scale oil refining projects. This system is included in the **Special Project for the Development of Intelligent Manufacturing Equipment**, and its implementation is carried out jointly by Zhejiang Zhongkong Group and Changle Refining & Chemical Company. Cao Xianghong, an academician of the Chinese Academy of Engineering, and relevant officials from the Ministry of Industry and Information Technology attended the acceptance meeting. 　　For a long time, the high-end intelligent control systems for major petrochemical projects in our country have been largely monopolized by foreign companies; these systems are expensive, which affects the economic efficiency of enterprises as well as the security of economic information. 　　With the support of Sinopec’s headquarters, in June 2012, Changling Refining & Chemical Co., in close cooperation with the system developer Zhongkong Group, successfully completed the installation, commissioning, and operation of the intelligent control system for the 8-million-ton refining plant. This marked the first time that an intelligent control system for a major Sinopec refining project was developed domestically, breaking foreign monopolies while saving nearly 5 million yuan in investment costs at one time. 　　Based on the 10-million-ton oil refining complex at Changling Refining & Chemical, this project develops intelligent control systems and related integrated application technologies. It establishes a real-time database for the entire plant, creating a unified automated platform for production process control, safety management, storage and transportation supervision, ****, and information integration. As a result, oil refining operations shift from traditional decentralized management of individual units to centralized management of multiple units, enabling intelligent monitoring and control across the entire process. 　　The successful localization of this system has not only shortened the product delivery time but also enabled the local supply of spare parts, playing a positive role in reducing implementation risks and ensuring project timelines for major oil refining projects. 　　As the first user of this system, reports from the Changling Refining and Chemical Plant indicate that it has been operating steadily for over 600 days since its deployment; its overall technical performance is at an internationally advanced level, with advantages in terms of redundancy features and control real-time performance compared to mainstream foreign products. The 10 combined refining units at Changling Refining & Chemical utilize this system for PID optimization, achieving an automatic control rate of over 95%; the stability of unit operation and the quality redundancy of the products are further improved, resulting in annual cost savings of 15 million yuan for the company. 　　The acceptance expert group believes that the system features high security, high reliability, and high stability, and its user-friendly operation interface fully meets the requirements for process control, monitoring, optimization, and management in large-scale production of petrochemical plants. 　　By 2014, this system had been adopted and implemented in refineries such as Maoming, Anqing, and Yangzi.
