Modeling And Simulation Of The Reaction Part Of Continuous Reforming Unit

Catalytic reforming process is an important process in the refining and petrochemical industries. With the emergence of the continuous reforming technology, the revolutionary breakthroughs of catalytic reforming technology took place, and it plays an important role in the catalytic reforming process. In this paper, the multi-scale modeling and simulation research, and process simulation of the continuous restructuring are studied, and the specific content is divided into the following areas:According to reaction mechanism, first, the steady-state model of the reactor is established and the simulation is carried out from the macro-scale, and next a novel four-lumping kinetic model of continuous reforming process is proposed, whose reaction kinetic parameter k integrates furnace outlet temperature, reaction pressure, Hydrogen-oil ratio, space velocity four main process factors. Then the dynamic model of continuous reforming reaction in the four continuous reactors is developed based on the proposed kinetic model and some hypothesis. Simulation studies are performed and the influences are analyzed. The simulation results show good agreement with the industrial process mechanism.In modern society, the environment makes increasingly high demand on the industry, and the emission regulations and product quality requirements also rise up precisely to the molecular level. Compare to the macro-scale model, the study and development of the micro-scale model could show the inner disciplinarian of the complex process, and it is very useful to predict component and quality of product, and optimize production. At the micro scale, by the known kinetic equation and kinetic constants, the molecular model and simulation of the continuous reforming reaction part is established. Simulation studies are also performed and the influences are analyzed too. The simulation results show good agreement with the industrial process mechanism.Currently, the process simulation has become a hot point in the modern society. By using HYSYS, the model of the continuous reforming reaction part was established and the model was based on a seventeen-lump kinetic model proposed before. Then a steady simulation on the model is implemented. Relative curves were derived and influences were analyzed. Finally, compared with the results of the MATLAB emulation, the model proposed in this paper proved correct.
