Mathematical Modeling of an Industrial Naphtha Reformer with Three Adiabatic Reactors in Series
Authors
Abstract:
A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehydrogenation, hydrogenation, ring expansion, paraffin and iso-paraffin cracking, naphthene cracking, paraffin isomerization and hydrodealkylation of aromatics. The kinetic model was fine tuned against industrial plant data using a feed characterized by PIONA (Paraffin, Iso-paraffin, Oleffin, Naphthene and Aromatics) analysis. The final outlet results of the reformer such as RON (Research Octane Number), yield and outlet reformate compositions have shown good agreement with actual conditions of Tehran Refinery reforming unit.

The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are clas...
full textModeling and Simulation of an Autothermal Reformer
The steady–state operation of the autothermal reformer is simulated as two reactors in series by means of a detailed mathematical model. An input-output model is selected to describe the upper combustion chamber. The possible occurrence of homogeneous steam reforming and watergas-shift (WGS) reactions is considered. The catalyst bed is represented through a one-dimensional heterogeneous model, ...

Manufacturing industry has witnessed a gradual transition from being a heuristic-driven labor-intensive set of processes to a sophisticated set of automation and model-driven processes where each operation unit in the production chain is automatically controlled and operated at a preset optimum regime. While incremental improvements in overall manufacturing efficiency have been steered by advan...
