Introduction As we all know, modern chemical industry is a continuous, large-scale production, technology-intensive, and high-risk industry. Many traditional manual on-site operations have been replaced by distributed control systems (DCS). High-quality skilled talents with solid chemical process theory and related production knowledge are increasingly in short supply, and cultivating high-quality applied talents who adapt to modernization has become an urgent issue. Therefore, optimizing the content of chemical engineering teaching courses and turning chemical engineering knowledge from books to practical applications is of great significance to the cultivation of high-quality chemical engineering technical talents. Chemical engineering simulation technology is a way to present the chemical production operation control environment in front of students through computers and construct chemical engineering theory. * A new teaching method that bridges the gap with actual chemical production. 1. Introduction to chemical engineering simulation teaching method Chemical engineering simulation technology is a technology based on actual production engineering, based on the structure and system rules of production equipment, and using mathematical models to reproduce chemical production equipment and process flows on the computer. It is a class that uses scene simulation and computer simulation to complete practical training projects of a certain comprehensive nature and cultivate students' comprehensive abilities. The entire teaching process uses simulation training software and does not focus on the training of the chemical unit operation process. Students can operate on simulated chemical equipment. The operation of chemical industry completely simulates the operating rules of real chemical equipment. Through operating software, students can strengthen their understanding of theoretical learning. * and the training of practical operational abilities. 2. Application of chemical simulation in teaching 2.1. For a chemical technical talent, the structure, working principle and simple operation room of basic chemical equipment must be mastered. However, in traditional teaching, these knowledge can only be taught through some written explanations and a few experiments. Students can meet the application requirements as they master the knowledge. For this reason, the chemical unit simulation software developed by Qinhuangdao Yuandao Technology Development Co., Ltd. introduced by our school covers fifteen units including CO2 compressor, conventional centrifugal pump, catalyst extraction tower, irrigation unit, boiler, heat exchanger, heating furnace, batch reactor unit, fixed bed unit, fluidized bed reactor, turbine centrifugal compressor, absorption analysis unit, distillation tower, liquid level control, and vacuum system, covering basic chemical equipment used in chemical production. Through simulation technology, the operation processes of starting, parking, and accident handling of each basic chemical plant are realistically simulated. Through the vivid and friendly human-machine interface operation, students not only master the basic knowledge taught in chemical engineering courses, but also learn the operation of basic chemical plant, which truly satisfies the cultivation of chemical technical talents. 2.2. Application of chemical engineering simulation in simulating typical chemical engineering processes. The working principles, technological processes, and operating procedures of typical chemical engineering processes are essential basic knowledge for chemical engineering technical talents. However, in traditional teaching, in addition to mastering the working principles, students can only be required to recite the process flow and learn * The process is extremely painful. The simulation system developed by Qinhuangdao Yuandao Technology Development Co., Ltd. introduced by our school covers four typical chemical processes: atmospheric and vacuum distillation, catalytic cracking-regeneration system, methyl acrylate imitation, and pyromellitic acid dianhydride process. Combined with simulation technology, the entire process flow can be simplified into a DCS control screen with pictures, text, audio and video presented in front of students. Students can follow the operating steps to understand and become familiar with the process flow. At the same time, they can analyze the impact of each work unit on the entire process by setting and adjusting working parameters. This not only deepens the understanding of the equipment and the entire process, but also stimulates students to learn. * interest, effectively improve classroom teaching efficiency and quality, and strengthen students' engineering awareness. It has laid a good foundation for cultivating qualified chemical technical talents. 3. The role of chemical engineering simulation teaching in cultivating students’ abilities 3.1. Building theoretical studies * The bridge with practical operation A qualified chemical technical talent should have a solid theoretical foundation in chemical engineering and be able to operate and control basic chemical equipment. The traditional teaching method pays more attention to the teaching of theoretical knowledge, while the practical training can only be through a few simple experiments and a few days of superficial training. Chemical engineering simulation technology can just fill this gap. While operating the simulation software, students enhanced their knowledge and understanding of theoretical courses. On the basis of mastering theoretical knowledge, enhance the understanding of chemical production and learn by operating simulation software. * The operational skills of chemical equipment can further enhance their understanding of theory and solve practical problems with theory, thus building a theoretical foundation. * A bridge to practical operations. 3.2. Strengthen the understanding of theoretical courses and the basis of practical chemical production training. The knowledge involved in chemical engineering professional courses is closely integrated with actual production. The courses involve many variables, complex formulas, and different types of equipment. If students are still learning in middle school, * way to conduct simple theoretical study * , it is difficult to achieve the desired effect. Combined with chemical engineering simulation technology, students can be introduced into the chemical production environment. This lively teaching method can improve students' learning. * interest and strengthen the understanding of theoretical knowledge. The chemical engineering simulation software contains many typical chemical engineering processes and realistic chemical engineering scenes. Students can conduct simulation training on it, so that students can have an immersive perceptual understanding of real chemical industry production and be able to perform practical operations on it, thus enhancing students' practical operation ability. After simulated training, students are then brought into the enterprise for chemical production training, which makes the superficial training become "flesh and blood" and truly brings into play the significance of the training. 4. Conclusion DCS chemical simulation technology can vividly and intuitively display the working principle, process flow and production process operation of chemical production equipment. Introducing it into chemical engineering teaching can enable students to strengthen their understanding of theoretical classes while operating the software. * An important bridge has been built between it and practical operation. In addition, the operation of simulation software can also lay a good foundation for chemical engineering training. Chemical engineering simulation teaching not only improves the teaching effect, but also improves the cultivation of students' comprehensive abilities, providing a good platform for cultivating outstanding chemical engineering technical talents.
