Dynamic Modeling and Simulation of Catalytic Naphtha Reforming H.M.Arani1, S.Shokri2, M.Shirvani3
Abstract—In this paper, according to the recent progresses in naphtha reforming technology, dynamic modeling of catalytic naphtha reforming process is studied. The dynamic model is composed of the reforming reaction model, the heat exchanger model, furnace model, which together, are capable to capture the major dynamics that occur in this process system. Kinetic modeling of the reactions of the fixed bed reactors connected in series form the most significant part of the overall simulation effort. MATLAB software in SIMULINK mode is used for dynamic simulation. Hougen-Watson Langmuir-Hinshelwood type reaction rate expressions are used to represent rate of each reaction.The results show models are in fair agreement with the actual operating data.

I. INTRODUCTION Catalytic naphtha reforming is an important process for producing high octane gasoline, aromatic feedstock and hydrogen in petroleum-refining and petrochemical industries. Advanced process control and process optimization strategies are important to be considered in catalytic reforming of naphtha due to its impacts on refineries profit. These are achieved mostly via a reliable mathematical dynamic model. The catalytic reforming process came into operation in refineries in the late 1940s. The reforming of naphtha feed stocks over platinum catalysts was pioneered by Universal Oil Products (UOP), with the plat forming process introduced in 1947. Concerning the kinetic modeling of the naphtha processes Smith [1] firstly proposed a four lumps model by considering naphtha as being composed of naphthenes, paraffins, aromatics and light hydrocarbons (
