|Abstract:||The present work undertakes simulation of the separation loop of a typical Continuous Catalytic Reformer (CCR)' process, using detailed analysis of feed and product streams on a steady state simulation software HYSYS of MIS 'HYPROTECH. The main aim of the present work is to develop a simplified model and to evaluate the utility requirements in the separation loop of CCR the process for various feed compositions. The data provided by M/S E.I.L., R&D Center Gurgaon for the CCR separation loop has been used as the base for the process simulation. The results of this simulation have been used to modify the base problem in order to meet the process requirements. Since the feed stock to the separation loop consists of more around thirty compounds, critical analysis of utility requirements for various feed stocks an extremely difficult task. Hence this problem has been simplified by lumping the feed components into five groups and replacing these compounds by pseudo-components there by reducing the number of compounds in the feed stream. The next stage of the present investigation was to carry out simulations on the simplified model for various feed compositions and evaluate the utility requirements for various equipments in the separation loop. The compositions of the five pseudo-component groups have been varied by ± 10% from the base case compositions. It was observed that, there is no interaction between the lump groups on prediction of utility requirements. The utility requirements change linearly with change in reactor effluent composition for different lumped groups and there is a good agreement between the results obtained for the actual problem and pseudo component problem. Hence pseudo components can be used to replace the actual feed stock components without any significant changes in the simulation results.|
