Abstract:
Catalytic reforming of heavy naphtha is an essential process in oil industries. A mathematical model isconstrcteded to describe the reactions inside the reactorsand to be applicaple for an industrial catalytic reformer unit.The industrial reformer reactor is considered as an ideal plug flow reactor. The reaction network consisted of naphthenedehydrogenation and paraffin dehydrocyclization reactions which are the main reactions that take place in the reforming process.Themodel describe conservation equations of mass and energyused to determine the outlet concentrations of paraffins, naphthenes and aromatics for the main reactions in the reformer. This model includes four sequencing moving beds of catalyst at the steadystate condition which is based on components aggregation into one group (C7). This model is used to estimate the outlet temperatures from the first and the second reactor by using the computer program Matlab. The estimated outlet concentrations and temperatures agrees very well withtheindustrial data which were shown by small percent deviation. Based on the model of the whole reforming process and process variable analysis;sensitivity analysis is conducted. the process is optimized. Therefore, the model can be used in monitoring the performance of similar reactors.
