Increased energy demand worldwide has caused faster depletion of sweet feedstock and
increased exploitation of sourer hydrocarbon fuels. These fuels often contain acid gases (H …

Hong Kong is highly vulnerable to energy and economic security due to the heavy
dependence on imported fossil fuels. The combustion of fossil fuels also causes serious …

Natural gas, refinery gas, and coal gas contain acid gases such as hydrogen sulfide (H2S)
and carbon dioxide that must be removed from the gas stream due to the toxicity of H2S and …

The modified Claus process is the major technology for the recovery of elemental sulfur from
H2S and SO2. A number of commercial technologies for the recovery of sulfur from acid …

Raw natural gas and crude oil contain a variety of sulfurous species such as H 2 S, COS, CS
2, mercaptans, and organosulfur complexes that lead to the formation of SO 2 and other …

Abstract Hydrogen sulfide (H 2 S), encountered in sour natural gas and in fossil fuel
refineries, has adverse health and environmental impacts, but also the potential to be a …

The principal technologies for H 2 S removal are reviewed herein. Two technologies in
particular, adsorption and catalytic oxidation, are considered as promising for desulfurization …

The development of accurate, flexible and robust dynamic reduced order models (ROMs) is
an important step towards greater commercialization of entrained flow gasifiers (EFGs). This …

H2S adsorption from dilute streams containing He, N2, CO2, CO, and H2O was studied
experimentally and by simulations for zeolites X and Y to evaluate their potential for Claus …

Hydrogen production from the thermolysis of undesirable hydrogen sulphide (H 2 S)
represents a viable means of extracting energy from it while enhancing the efficiency of …
