Process description of dry desulfurization. Dry desulfurization is precision desulfurization. The equipment's fundamental principle of dry desulfurization is oxidizing the H 2 S to sulfur or sulfur oxides, which can be described as a dry oxidation process. After the concentration of H 2 S is desulfurized to <150 mg/m 3 by wet ...
