H2S Removal's Significance
Hydrogen sulfide is a highly toxic gas second only to cyanide. Its molecular formula is H2S. At low concentrations, it smells of rotten eggs and is highly toxic. Hydrogen sulfide is a flammable and hazardous chemical. It can form an explosive mixture when mixed with air, which can cause combustion and explosion in case of an open fire and high heat energy.H2S gas not only seriously threatens people's life safety and pollutes the environment but also causes serious corrosion damage to metal equipment and tools. Therefore, the removal of hydrogen sulfide is very important!

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.The used desulfurizer can be regenerated, but considering the quality of the regenerated desulfurizer, regeneration cost, regeneration conditions, and other factors, regeneration is generally not recommended. If the customer insists on regeneration, he must strictly follow the operation manual and control the regeneration conditions.Desulfurization stage: Fe2O3

Why us?
The history of iron oxide desulfurizer was first developed and used by European and American countries, and it was originally used for the removal of hydrogen sulfide (H2S) gas in coal gas. The initial desulfurizers were less efficient, with a sulfur capacity between 5% and 6%, and low porosity. Through continuous improvement and tackling, the quality of iron oxide desulfurizer has been continuously improved, and the sulfur capacity has been gradually increased.Mingshuo Group is derived from a state-owned catalyst factory and is a large-scale iron oxide desulfurizer production base in China. Over the years, Mingshuo has solved technological problems through continuous research and development, and developed MT-1 type iron oxide desulfurizer with a sulfur content of more than 12%, and MT-2 type iron oxide desulfurizer with a sulfur content of more than 20%. The sulfur capacity of ferric oxyhydroxide desulfurizer has reached more than 30%, and the sulfur capacity can be adjusted freely within the interval. The sulfur capacity adjustment of our iron oxide desulfurizer can be produced according to customer needs, which can meet the needs of different customers in different industries!
