Product Description

 

Product Description

Chelated Iron Wet Desulfurization Redox Scrubber for Sulfur Removal/ Absorption
The MC type chelated iron desulfurization catalyst is independently developed and produced by our company. It is primarily used for the removal of hydrogen sulfide from biogas, natural gas, semi-water gas, coke oven gas, petroleum refining gas, and other gases. This chelated iron desulfurization catalyst contains iron ions and has a weakly alkaline solution. It boasts a high sulfur capacity, strong resistance to fluctuations in hydrogen sulfide concentration, and a high removal efficiency for hydrogen sulfide. The single-pass removal effect can reach up to 99%.
The ML type chelated iron desulfurization complexing agent is also independently developed and produced by our company. It is mainly used for the removal of hydrogen sulfide from biogas, natural gas, semi-water gas, coke oven gas, petroleum refining gas, and other gases. The product is primarily composed of a small molecular complexing agent and a selective pH buffer. It plays a role in stabilizing ferrous ions and promoting electron transfer during the regeneration process in the binary structure system of the chelated iron desulfurizer.
