Supcon Technology has accumulated rich experience in large-scale refining and chemical integration This is an important reason why Guangdong Petrochemical chose to cooperate with Supcon Technology.”

Build the national production of the core control system

Such a large-scale refining and chemical project has extremely strict requirements on the stability and safety of the control system. Up to now, in this project, the control system has reached 170,000 I/O control points, 2165 cabinets, 1210 consoles, and 277 pairs of controllers, 13,924 pieces of I/O cards, and 178 sets of servers… set new records for the localization of core control systems in the petrochemical industry, and also witnessed the unique advantages of central control technology in the field of control systems.

In addition, PetroChina Guangdong Petrochemical Refining and Chemical Integration Project has a total of 46 sets of process equipment, and at the same time supporting the construction of 300,000 tons of crude oil docks, long-distance pipelines, crude oil transfer depots, sewage treatment and other supporting projects. What attracts the attention of the industry is that the aromatics plant, polypropylene plant, and styrene plant are all the largest single sets in the world, and the requirements for the safety and reliability of the control system are higher than those of conventional 10 million-ton oil refining projects. Xu Li said that the whole process of Guangdong Petrochemical Refining and Chemical Integration Project has been opened up, and the first condition for realizing operation is that the central control technology control system plays an important role in guaranteeing the continuous stable, safe and efficient operation of the project.

Before applying the localized control system, Guangdong Petrochemical had conducted on-the-spot research on the application of Zhongtian Hechuang’s large-scale coal-to-olefins and the National Energy Group’s Ningxia Coal Industry’s large-scale ethylene and other similar projects. Application of technical control system. (The Zhongtian Hechuang project was the largest plant-wide DCS control system application project in China at that time. It was the first time to realize the overall application of the domestic DCS control system (Central Control Technology ECS-700) in the entire process of a large-scale modern coal chemical project, and the technical indicators reached International advanced level, economic and social benefits are remarkable). From the central control technology ECS-700 control system to the new generation of full-process intelligent operation management and control system (i-OMC), the central control technology has never stopped exploring and growing in the field of control systems. In Guangdong Petrochemical Refining and Chemical Integration Project, SUPCON Technology applied the concept of i-OMC system construction to break through the integration of planning and dispatching of the whole plant, realizing top-down production synergy, optimization and integrated control.

On the coast of the South China Sea, there are towers like forests. In the invisible space, Supcon Technology, with its powerful data processing capabilities, assists in compatibility, openness and scalability, and uses simplicity to control complexity, which not only ensures the safe and stable operation of all equipment in Guangdong Petrochemical Refining and Chemical Integration Project , It also improves the efficiency of equipment operation and reduces the cost of operation and maintenance, providing a strong boost for this world-class refining and chemical base.

The whole process operation optimization management is moving towards a high degree of intelligence

This project is the only refining and chemical base at home and abroad that can process all low-quality heavy oil. It is a successful practice of PetroChina to realize the domestic refining and chemical business moving towards the middle and high end of the industrial chain and value chain. The construction of high-end and intelligent factories has become the construction of this project. Notable requirements in . As the automation system contractor of this project, Supcon Technology directly participates in the high-standard and high-quality delivery of the contents of the MAC framework to ensure the best execution of all systems, and assists users in providing technology, engineering execution, and project support for the smooth implementation of large projects. On the basis of management and other support, the use of “factory operating system + industrial APP” is used as the key path to build a smart factory. By adopting the construction concept of Supcon’s new generation of full-process intelligent operation management and control system (i-OMC), with the factory operating system as the unified data base, the control system and industrial application software are perfectly connected from top to bottom, deeply integrated and coordinated operations. Among them, including plant operating system, instrumentation management (IDM), operation data management (CDP), advanced control (APC), online analyzer maintenance and data acquisition (AMADAS), storage and transportation automation (oil blending, oil movement, Automatic loading and unloading truck/ship), operator training simulation (OTS), industrial control network security, instrument intelligence (PID evaluation and tuning, ALMS alarm management, SOE accident analysis, control system integrity, failure database, server virtualization), etc., Empower all professionals in the factory, realize the integration of control + optimization + management, and help PetroChina Guangdong Petrochemical Refining and Chemical Integration Project create a new situation in building a green, intelligent, and profitable world-class refining and chemical base.
