Dry Iron Oxide Desulfurizer of Mt Series
The most common method in dry desulfurization is iron oxide desulfurization. By passing the feed gas through the desulfurizer bed at room temperature, the H2S in the feed gas contacts the active iron oxide to generate iron sulfide and ferrous sulfide. When the sulfur content of the outlet gas exceeds the standard, the desulfurizer should be replaced with new ones.
MT series of iron oxide desulfurizer is mainly used for the removal of hydrogen sulfide produced by city coal gas, chemical fertilizer plant, coking plant, citric acid factory, brewery, metallurgy, textile industry, light industry and environmental protection industry. This series of products has the characteristics of convinent operation, fantastic adaptability and small resistance in use.
The principle of desulfurization and regeneration is as follows:
Fe2O3 · H2O+3H2S=Fe2S3· H2O+3H2O
According to the above equation, we can see that the absorption of H2S into Fe2S3 by Fe2O3, with the continuous generation of biogas, ferric oxide absorbs H2S, when the absorption of H2S reaches a certain amount, the removal rate of H2S will be greatly reduced, until the failure.
Fe2S3 can be recycled, and O2 and H2O chemical reaction can be reduced to Fe2O3, the principle is as follows:
2Fe2S3 · H2O+3O2 = 2Fe2O3 · H2O+6S
Combined with the above two reactions, the biogas desulfurization reaction is as follows:
H2S+1/2O2 = S+H2O: (Reaction condition is Fe2O3 · H2O)
From the above chemical reaction equation can be seen, Fe2O3 absorption of H2S into Fe2S3, Fe2S3 to be reduced to Fe2O3, requires O2 and H2O, through the air compressor in the desulfurization tower before adding air to the biogas can meet the desulfurization agent to restore O2 Requirements, biogas contains saturated water can fully meet the desulfurization regeneration of water requirements.
