The invention discloses a process for preparing sulfur by reducing sulfur/nitrate iron-carbon and recovering desulfurization/nitration agent. High - concentration SO2 flue gas generated by sulfate calcination and NOx generated by nitrate heating and decomposing can be combined with iron-carbon. The carbon material is directly reduced to elemental sulfur steam and N 2 by reaction at high temperature, and then the sulfur is recovered by the sulfur recovery device after successively going through the processes of dust removal, cooling and fine dust removal. ) agent raw material, this process can realize the recycling of desulfurizer and denitrification agent. |
