Abstract
A system and method including a sulfur recovery system (SRU) having a Claus system, reacting hydrogen sulfide and oxygen in a furnace to give sulfur dioxide, performing a Claus reaction in the furnace to give elemental sulfur, performing the Claus reaction in a Claus reactor to give elemental sulfur at a temperature greater than a dew point of the elemental sulfur, performing the Claus reaction in a Claus cycling reactor to give elemental sulfur at a temperature less than a solidification temperature of the elemental sulfur, depositing the elemental sulfur as solid elemental sulfur on catalyst in the Claus cycling reactor, and regenerating (heating) the Claus cycling reactor thereby forming elemental sulfur vapor from the solid elemental sulfur.
