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.
Claims8
A method of removing hydrogen sulfide and hydrogen polysulfide from liquid sulfur, comprising the steps of:
- injecting a first sparging gas through a plurality of circular holes in a multi-chambered sparging gas mat;
- agitating the liquid sulfur with the sparging gas in a first cell;
- transferring the agitated liquid sulfur to a second cell;
- injecting a second sparging gas through a second multi-chambered sparging gas mat and agitating the transferred liquid sulfur in the second cell;
- and
- removing hydrogen sulfide gases and hydrogen polysulfide gases from a headspace in communications with the first cell and the second cell.
