1. Explain with the chemical reactions listed below why the desired oxygen/hydrogen sulfide ratio in the feed to the Burner Reactor used in the Claus Process should be 1/3 of the stoichiometric oxygen/hydrogen sulfide ratio to theoretically achieve a complete removal of all sulfur species so that no H₂S or SO₂ would be leaving The Claus Unit. Note: Stoichiometric ratio (O₂/H₂S) for complete combustion of H₂S = 3/2. 30 pts

H₂S +(3/2)O_2 -->H₂O +SO₂ (1) Combustion Reaction

2H₂S +SO_2-->2H₂O +3S (2) Conversion Reaction
