Investigating the Effect of Pressure and Heating Method on the Performance of Hydrodesulphurization Reactive Column

In the new Hydrodesulphurization (HDS) process, by integrating the reaction and separation units in a single reactive column, the fixed cost and operational costs can be reduced, as well as more flexible operating conditions will be achievable. Computer simulation is necessary for investigating both the design and operating aspects of reactive columns. This study was performed in different condition such as various temperatures and pressure for gas oil feed, using the software developed in Research Institute of Petroleum Industry (RIPI) which possesses high flexibility. In this paper, the results of substitution Langmuir - Hinshelwood instead of Power low kinetic equation in model for investigating the pressure variation effect, and the results of changing the feed temperature and column heating method are presented. The achieved results show the effect of operating pressure and heating method on the performance of the HDS reactive column. Moreover, simulator capability for applying the rigorous kinetic models and computation convergence was confirmed.
