Numerical Simulation of a High-Pressure Reactive Furnace in Recovering Sulfur from Sour Gas.

Nowadays, the Claus process is one of the most efficient procedures to recover sulfur from acid gases. In the current study, the effect of working pressure and the role of initial species (sour gas, ammonia, carbon dioxide, hydrocarbon, nitrogen, and oxygen) are analyzed using COMSOL software. The reaction occurs between acid gases, which contain 88% HS, 10.
