Method for removing hydrogen sulfide from biogas |
| abstract |
The present invention provides a method for removing hydrogen sulfide from a biogas that can remove hydrogen sulfide contained in the biogas without providing a large desulfurization tower in the biogas line. The removal method includes a step of supplying biomass to an anaerobic fermenter; a step of fermenting the biomass to obtain biogas and an anaerobic fermentation liquid; a step of draining the anaerobic fermentation liquid; A step of aggregating with an iron-based flocculant; a step of separating the agglomerated sludge to obtain a concentrated sludge containing the iron-based flocculant; a step of returning at least a part of the concentrated sludge to the anaerobic fermenter; And recovering biogas from the anaerobic fermentor to which the concentrated sludge has been returned.
