The Modified Claus process is the most common method for removing hydrogen sulfide from natural gas. Despite studies conducted on the simulation of catalytic beds in sulfur recovery units, no comprehensive research has yet been carried out on the impact of sulfur capillary condensation on catalyst deactivation. In the present study, dynamic modeling and simulation of sulfur production processes in catalytic beds were performed, considering the Claus reaction and hydrolysis. After validating the proposed mathematical model, the distribution of operational parameters such as temperature, pressure, and component concentrations, taking catalyst deactivation into account, was analyzed. The results from the simulation showed that, for the current case study, approximately 80% of the catalyst deactivates after 300 days of loading in the bed due to sulfur capillary condensation, resulting in a more than 49% reduction in sulfur production.
