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...

Quality of sulfur deposits collected from hydrogen sulfide combustion has been examined. Experimental conditions representing selected practical systems have been investigated. Combustion of hydrogen sulfide was allowed to occur under the different conditions with sulfur deposits collected for...

A reduction strategy of hydrogen sulfide/oxygen reaction mechanism is conducted to simplify the detailed mechanism. Direct relation graph and error propagation methodology (DRGEP) has been used. A novel approach of direct elementary reaction error (DERE) has been developed in this study. The...

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....

Results are presented to examine the combustion of acid gas (H2S and CO2) in hydrogen-fueled flames using a mixture of oxygen and nitrogen under Claus conditions (Φ=3). Specifically the effect of oxygen enrichment in the above flames is examined. The compositions of acid gas examined are100%...

Investigations on the effect of acid gas (H2S and CO2) addition in hydrogen/air flame are presented. The specific equivalence ratios examined include Claus conditions (Φ=3.0) as well as stoichiometric conditions (Φ=1.0) and fuel-lean conditions (Φ=0.5). Two different acid gas compositions of...
