Continuous Catalytic Reforming Unit

One of the most important processes in any refineries is naphtha catalytic reforming. In this process gasoline with high octane number is produced. In petrochemical complexes expensive aromatics such as benzene, toluene and xylene by this process are also produced. According to the importance of fuel and producing more gasoline from oil raw material and the possibility of optimization and improvement of catalytic reactor operation to increase the quality and quantity of products, simulation and checking the process parameters and improvement in its operation seems to be necessary. This process consists of three radial flow reactors, Furnaces, separator vessels, a number of heat exchangers and compressors. In these reactors more than three hundred reactions happened. To simulate these reactions the presented kinetic models should be used. In Refineries the inlet temperature of three reactors are the same but as the catalyst activity decreases this temperature increases based on the products quality. Also change in entrance feed features and its flow fluctuations affect products distribution and products octane number and make it unstable
