 Performance and capacity of sulfur recovery unit (SRU) are greatly affected by the H2S:CO2 ratio of the acid gas stream. The acid gases in Iran contain around 35 mol% H2S and 60 mol% CO2. This low concentration of H2S calls for more complex sulfur plant, larger equipments, and higher costs. Acid gas enrichment processes (AGE) is run to upgrade low quality acid gas collected from gas treating...
