The removal of hydrogen sulfide from natural, industrial of bio gas is an operation that is frequently encountered in process industry. Driven by tight sulfur specifications and the everlasting need for cost reduction a considerable research effort is made in this field,\ud
sprouting numerous new developments in desulfurization technology.\ud
The procede desulfurization process is a regenerative process that is capable of removing H2S from a gas stream without the uptake of CO2. The removal of H2S is selective since the absorption process is based on the precipitation reaction of H2S with metal ions present in an aqueous solution under the formation of metal sulfide
