Process for the selective removal of hydrogen sulfide from gaseous streams

Patent ·
OSTI ID:6706835
;

A process is described for the selective removal of hydrogen sulfide from a gaseous stream, additionally containing carbon dioxide, by contacting the gaseous stream with a polyvalent metal chelate solution. The pH of the polyvalent metal chelate solution is greater than 7 and is constant because the net absorption-desorption of the carbon dioxide in the solution is zero. The contacting is for a time sufficient to allow the polyvalent metal solution to oxidize the hydrogen sulfide to elemental sulfur precipitate.
