Sulfur Removal & Recovery
| Technology Overview | Flow Diagram | Project Case |
Liquid phase oxidation process for sulfur removal utilizes complex iron ions as the catalyst, hydrogen sulfide dissolves in the solution when feed gas and catalyst solution contact each other. Hydrogen sulfide-rich solution is regenerated by air entering the oxidation tower. By circulation, hydrogen sulfide will be oxidized to sulfur, and to become a filter cake through filtration. This technology can also adopt self-circulation way, combining absorption column and oxidation column, so absorption and regeneration can happen at the same time.
