The present invention includes a process for the removal of hydrogen
sulfide from hydrogen sulfide gas containing gaseous streams. In one
embodiment, the process comprises feeding a sulfide ion containing
solution to an oxidation unit. The method further comprises feeding an
oxidizing gas to the oxidation unit and contacting the sulfide ion
containing solution with the oxidizing gas under sufficient conditions to
form a polysulfide solution comprising polysulfide and hydroxide ions. In
addition, the process comprises mixing the polysulfide containing
solution with a hydrogen sulfide gas under conditions sufficient for
absorption of hydrogen sulfide and precipitation of sulfur from the
polysulfide containing solution. In some embodiments, the process
comprises separating the precipitated sulfur from liquid.
