Evaluation of economic feasibility for dry-type desulfurization process by iron chlorides dosing in biogas plant |
| 초록 |
Hydrogen sulfide(H2S) creats sulfur oxides by combustion. Biogas has a high concentration of hydrogen sulfide without special treatment. In order to reduce the air pollution by hydrogen sulfide, anaerobic digestion plant should take the special treatment. In this study, it was checked to validate the process influence by dosing of iron chlorides(FeCl2 or FeCl3), and the economic feasibility was evaluated for pre-treatment of dry-type desulfurization process. Iron chlorides dosing showed a good performance to reduce H2S in biogas. H2S concentration was reduced about 86% by 200kg/day iron chloride dosing. Also, the amount of biogas production and methane content increased about 25% and 6%, respectively. The total cost for operation using the dry-type desulfurization process reducd by up to 69% when the concentration of H2S was controlled with FeCl2 or FeCl3 dosing in anaerobic digester. |
