Abstract
A novel system and method for degassing H2S and H2Sx from liquid sulfur (sulphur) is disclosed. The system includes a degassing vessel with a plurality of cells. The cells include a sparging gas mat with a perforated surface at the bottom of the cell to allow the release of air bubbles (or sparging gas) into the cells. A catalyst may be used during the process. As a result, hydrogen sulfide and hydrogen polysulfide are efficiently and effectively removed from the liquid sulfur.
