Not only do the natural gas and petroleum industries face the challenge of stringent sulfur compound emission limits, but it is also important to use new technologies to reduce the carbon footprint and improve energy efficiency. Herein this research

Methanol is commonly used as a hydrate inhibitor in gathering and transportation systems for natural gas streams containing H2S. While efforts are made to prevent carryover, some residual methanol can end up reaching downstream facilities. If residua

Current regulations of SO x emissions require Sulfur Recovery Units (SRUs) to achieve recoveries in excess of 99.9%. Capital cost of existing commercial Claus Tail gas clean up technologies capable of achieving that benchmark can amount to 45% of the

A stirred-glass autoclave containing liquid sulfur and solid iron oxide catalyst was used to study low-tonnage sulfur recovery from H2S-containing gas streams. The objectives were to test the feasibility of using both liquid sulfur as a reaction medi

The oxidative dehydrogenation of propane to propene at short contact times over V2O5/A12O3 was remarkably enhanced by the introduction of H2S in the feed mixture. Overall conversion of propane over this catalyst at 700 °C and 5 ms contact time was 5

Use of the equilibrium sulfur vapour system as the basis for a thermochemical solar energy conversion system is suggested. This chemical system is shown to be both thermodynamically and kinetically well suited, as well as possessing several other des

The pyrolysis of hydrogen sulfide has been studied at residence times between 0.4 and 1.6 s and in the temperature range of 800−1100 °C. A continuous perfectly mixed quartz reactor was used to acquire kinetic data on the thermal dissociation of hy

The aim of this study was to determine the major pathways leading to COS and CO formation and consumption during the processing of H2S and CO2 in the partially oxidizing conditions of the Claus furnace. Both species were found to be produced by a mul

The results of the previously reported kinetic study of the reaction between H2 and sulfur, H2 + 1/2S2 = H2S, under Claus furnace conditions (Dowling; Hyne; Brown. Ind. Eng. Chem. Res. 1990, 29, 2327), have been reevaluated using a more rigorous anal

Free energy calculations and experimental measurements have been used to show that H2S/CO2 mixtures outgassing from a prebiotic Earth's crust would have produced a reducing gas mixture containing CO, H2, H2O, and Sx as principal components. Due to ra
