The activity loss modeling of catalytic reactor of sulfur recovery unit in South Pars Gas Complex (SPGC) 3rd refinery based on percolation theory

摘要

Claus process is one of the processes that used in gas refineries to convert hydrogen sulfide to elemental sulfur. With respect to importance of activity of catalysts, which plays determinant role in keeping total efficiency of this process, modeling and simulation of catalytic bed and prediction of the time period for deactivation of beds may essentially contribute to better exploitation from the given unit.
