INTRODUCTION
Hydrogen sulfide is present in numerous gaseous waste streams from natural gas plants, oil refineries, wastewater treatment, among other processes. These streams usually also contain carbon dioxide, water-vapor, trace quantities of hydrocarbons, sulfur and ammonia. Waste gases with ammonia are called sour gases, while those without ammonia are called acid gases. Sulfur must be recovered from these waste streams before flaring them.
Sulfur recovery from sour or acid gas typically involves application of the famous Claus process (1) using the reaction between hydrogen sulfide and sulfur dioxide (produced in the Claus process furnace from the ...
