Abstract:
A method for treating a hydrogen sulfide-containing waste gas stream comprising the steps of:a. introducing hydrogen sulfide-containing liquid sulfur into a containment vessel to partially fill the containment vessel and create a hydrogen sulfide-containing liquid sulfur phase and a hydrogen sulfide-containing vapor phase; b. treating a portion of the hydrogen sulfide-containing liquid sulfur phase to produce a liquid sulfur-containing phase and a gaseous hydrogen sulfide-containing phase, the gaseous hydrogen sulfide-containing phase having a pressure of at least about 60 psig; c. withdrawing a portion of the hydrogen sulfide-containing vapor phase using at least one eductor driven by a motive fluid, where the motive fluid is the gaseous hydrogen sulfide-containing phase; and d. treating the hydrogen sulfide-containing waste gas stream exiting the eductor to reduce the hydrogen-sulfide content of the waste gas.
