Experimental results are presented on the role of benzene addition to H2S combustion at an equivalence ratio of three with respect to H2S (Claus condition) and complete combustion of benzene. The results are reported with 0.3%, 0.5% and 1% benzene addition to H2S/O2 flame. Combustion of H2S and...

The Effect of the presence of nitrogen and carbon dioxide in H2S acid gas stream is investigated. Concentrations of up to 30% of N2 or CO2 in H2S stream have been examined. All cases were compared with the baseline case of 100% H2S acid gas stream. Temperature measurements showed that injection...

Experimental investigations on the effect of different amounts of toluene addition to H2S combustion in oxygen under Claus condition (Φ=3) are presented. Three toluene concentrations of 0.5%, 1% and 5% in H2S are presented and compared with the baseline case of 100% H2S oxygen combustion....

Investigation of sulfur chemistry of hydrogen sulfide in methane/air flame under different equivalence ratios is conducted. A range of equivalence ratios extending from fuel-lean (Φ=0.5), stoichiometric (Φ=1.0), to fuel-rich (Claus condition, Φ=3.0) are examined here. Hydrogen sulfide,...

Results are presented on the toluene destruction using oxygen enriched air as the oxidant with addition of defined amounts of H2S and toluene into H2/air flames under fuel-rich mixture conditions at equivalence ratio of Φ=3 (Claus condition). The oxygen enrichment allowed variation of...
