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

Abstract

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 O 2 concentration, temperature of main burner increased monotonically. It is found that sulfur recovery (in the O 2 high concentrations) increases up to a maximum value and then decreases with increase of O 2 concentration, while this is not the case for O 2 low concentrations.

“…The gases leaving the sulphur condenser are reheated and fed to the first catalytic reactor, where more sulphur is produced. The Catalyst (DD-431) is the common catalyst used in sulphur recovery process (Asadi et al, 2013). The gases leaving Reactor1 are again cooled and sulphur is condensed and routed to the sulphur collector.…”
