refractory selection guide for sulphur recovery units
Sulphur Recovery UnitEnggCyclopedia
The basic process used in sulphur recovery unit (SRU) is Claus Process which involves combustion of a part of H 2 S gas to form SO 2.Later this SO 2 is reacted (conversion) with H 2 S in presence of catalyst (Cobalt / molybdenum / aluminum oxide ) to form elemental sulphur and steam.. The main chemical reactions involved are 2H 2 S 3O 2 → 2SO 2 2H 2 O (Combustion reaction) 4H 2 S
