Abstract
Sulfur is one of the most important products in the processing of oil and gas, which is used in important industries such as sulfuric acid production and agriculture. Hence, the improvement of the efficiency of sulfur production processes at the industrial scale has paid a lot of attention. Due to some process problems such as the presence of heavy aromatic compounds and inappropriate temperature, the efficiency of this unit decreasesTherefore, in this paper, the steady state simulation of the modified Claus process of the Sulphur Recovery unit of the first refinery of the South Pars Gas Complex using Aspen Plus software has been done. The dynamics of CO2 concentration and furnace temperature were also studied. The simulation accuracy is desirable in the stable and dynamic state, so that the average error for the simulation flow data compared to the industrial data is 2.52% and 2.11% for the dynamic and dynamic mode, respectively. In addition, the results indicate an increase for sulfur produced by increasing the furnace temperature and reducing the concentration of CO2.
