ABSTRACT:
A method of recovering sulfur from gaseous materials containing hydrogen sulfide is provided having the steps of reacting a first gaseous material with first oxidizing gas in a first reaction step to form first products of incomplete combustion including primary gaseous sulfur, sulfur dioxide and uncombusted hydrogen sulfide; cooling said first products of incomplete combustion in first cooling means; directing a first fraction of the cooled first products of incomplete combustion to first condensing means; condensing the first reaction of the cooled first products of incomplete combustion in the first condensing means to form collectable sulfur and gaseous product; reacting the gaseous products leaving the first condensing means and the remaining fraction of the cooled first products of incomplete combustion with second oxidizing gas in a second reaction step to form second products of incomplete combustion including gaseous sulfur; cooling the second products of incomplete combustion in second cooling means; and condensing the second gaseous sulfur from the cooled second products of incomplete combustion in second condensing means to form collectable sulfur.
