Effect of O2 Concentration on the Reaction Furnace Temperature and Sulfur Recovery Using a TSWEET^® Process Simulator

Asadi S, Hamed Mosavian MT and Ahmadpour A

In the present study, effect of a parameter for increasing the reaction furnace temperature and sulfur recovery of Claus sulfur recovery units (SRUs) is investigated by TSWEET process simulator based on Gibbs free minimization. The effect of oxygen enrichment on the reaction furnace temperature and sulfur recovery has been studied by proposed simulator. In the case of the effect of O2 concentration, temperature of main burner increased monotonically. It is found that sulfur recovery (in the O2 high concentrations) increases up to a maximum value and then decreases with increase of O2 concentration, while this is not the case for O2 low concentrations.
