摘要

The removal of hydrogen sulfide(H2S)from produced gas,oil and water has been a challenge to producers for many years.H2S is a highly toxic,corrosive and undesired component,produced alongside both liquid and gaseous hydrocarbons.It originates from either biological or geological processes,which occur in the reservoir formation over long periods of time.H2S is relatively widespread and must be removed prior to export of hydrocarbon gas and fluids.Produced gas can,quite commonly,have many thousands of parts per million(ppm)H2S,and in some areas can reach tens of percent(in some Canadian gas wells there is more H2S than methane).Chemical removal of H2S,which is the major focus of this article,is typically constrained to gas concentrations of 5,000 to 10,000 ppm of H2S.Beyond these concentrations,other methods are used,such as amine recycling units or steam stripping units.
