Method for substantially complete removal of hydrogen sulfide from sulfur bearing industrial gases |
| abstract |
Hydrogen sulfide is substantially completely removed from a sulfur bearing industrial gas stream by absorbing the H 2 S into a liquid absorbent, stripping the absorbent of absorbed H 2 S and reacting it with SO 2 in a ratio of H 2 S/SO 2 greater than the stoichiometric ratio of 2.0:1.0 to produce elemental sulfur and water, leaving a tail gas containing an excess of hydrogen sulfide but no sulfur dioxide. At least the last stage of the reaction is carried out in a liquid reaction medium at a temperature not greater than 160° C. The excess H 2 S assures complete reduction at these temperatures of all SO 2 to elemental sulfur. The remaining excess H 2 S is then recycled in the tail gas back into the original industrial gas stream prior to the point of contact of the industrial gas stream with the liquid absorbing solution. |
