MODELLING OF THE ISOMERIZATION PROCESS FOR THE PURPOSE OF ADVANCING MOTOR GASOLINE QUALITY

The isomerization process is important in the production of motor gasoline due to its role in improving light gasoline fraction applicative properties. This paper stresses the importance and application of the isomerization process advancement using modeling. A mathematical model of the chosen isomerization model was defined. While setting the model, the process was explored from the viewpoint of reaction mechanism, isomerization reactions kinetics and chemical balance parameters. The reactor simulation model has been elaborated according to the set material balances, while the model also describes the heat exchange processes, as well as those of substance exchange using separation procedures. The set simulation model has enabled research of optimal operating process conditions using simulation, and process advancement has been suggested from the viewpoint of increasing the yield of the high octane isomerization process product, as well as the yield of the product octane number. The results obtained through the simulation of the process advanced by the addition of the deisopentanizer column have shown an increased isomerate yield by as much as 42% compared with the process without advancement, while process implementation by adding molecular sieves has resulted in a considerable increase of the product research octane number of 9 units. The results of simulating the implemented isomerization process variants have shown a very good match with the experimental data of the industrial process. Although the economic aspects of the improvements are not addressed in this paper, it can be assumed that the solution involving the deisopentanizer column would probably be most economic.
