abstract = "The presence of contaminants in the acid gas produced from natural gas sweetening has a significant impact on the operating conditions of Claus furnace required for maximum sulfur recovery. Carbon dioxide, nitrogen, and water vapor are the most common contaminants that accompany hydrogen sulfide in the acid gas stream. In this paper, equilibrium and chemical kinetic analyses are conducted on acid gas that contains carbon dioxide, nitrogen, and water vapor along with hydrogen sulfide. The objective of the equilibrium investigation is to find the optimum operating temperature for the Claus furnace that provides maximum sulfur recovery for different acid gas compositions. On the other hand, the objective of the chemical kinetic analysis is to study rigorously the reactions that occur in isothermal and adiabatic Claus furnace in order to compare the behavior of both reactors. Our equilibrium investigations indicate that the presence of contaminants decreases the optimum operating temperature and the sulfur conversion efficiency. Meanwhile, our chemical kinetic analysis revealed the main reaction that is responsible for the reduction of sulfur recovery in adiabatic Claus furnace and the factors that has a direct effect on this reaction. Equilibrium and chemical kinetic analyses are based on numerical simulations.",
