Design Of Experimental Simulation Training System For Diesel Catalytic Hydrogenation

As one of the important processing techniques in the petrochemical industry,the catalytic hydrogenation process has been widely used in the refining process of oil.Many universities have also carried out relevant experimental research.In the modern industrial development environment of digital and informationization,the country has put higher requirements on the safety of industrial production.Due to the existence of many flammable,explosive,high-temperature high-pressure,and toxic and harmful substances in the production process of catalytic hydrogenation,as well as the complexity of equipment unit,once any mistake in any production processes occur,it may lead to an accident,which often triggers a domino effect and exacerbates the consequences of the accident.Based on the research on safety accident cases of chemical enterprises and university laboratories,human error is the main cause of accidents.Therefore,strengthening the cognition of production process and safety operation awareness of workers is a key measure to prevent accidents.According to the drawbacks of previous chemical safety practical training,such as dull content,poor intuitiveness,and low participation of trainees,this paper takes a small-size catalytic hydrogenation experimental device as the simulation reference object.By utilizing the advantages of visualization technology to design virtual twin models,simulation interaction scripts,and process mechanism algorithm,a catalytic hydrogenation experimental simulation system is developed based on Unity 3D.Through the studies of the principles of catalytic hydrogenation experiments,the processes of experimental equipment,the operating logic of units,and the risk identification of the production process,the actual needs of simulation experiment training are determined.Based on the needs analysis,the system is developed,which realizes dynamic interactive operations,virtual simulation of equipment,experimental process simulation,risk identification interaction,as well as auxiliary functions,including theoretical learning,user management,data management and others.It provides support for the integration of safety systems engineering,industrial process simulation,and digital information technology,and provides high-fidelity,strong immersion,safe and efficient,user-friendly training methods for experimental training personnel,effectively improving their knowledge of process and safety practice level.
