Development of A Procedure to Improve The Efficiency and Yields of The Gasoline Production Process Through Pseudo-Dynamic Kinetic Modeling and Optimization

Different sets of experiments were designed and conducted in a pilot plant to determine the effect of different operating conditions on the process efficiency and deactivation of the catalyst in the naphtha catalytic reforming process. Based on the experimental results, a kinetic model was developed and adapted for the purposes of prediction. The developed model represents the impacts of all input variables – including operating conditions, physical properties of feedstock, and chloride injection – on research octane number (RON), the yields of reformate l, and outlet reactor temperatures. Finally, by applying the model and an optimization algorithm, a pseudo-dynamic optimization of the process was carried out to minimize energy usage and improve the process efficiency by determining an optimum operating plan that also maximizes the yields of the average octane number and the liquid product. Also, by minimizing the increasing rate of weight average bed temperature of the reactors, the average energy consumption throughout a definite period was minimized. Finally, it is also estimated that by applying this method, the average conversion and average RON could be improved by ۶% and ۲.۵ units respectively.
