Hydrogen Sulfide is a very volatile dissolved gas and readily escapes as a gas into the air causing unpleasant odors. Once hydrogen sulfide leaves the dissolved phase and enters the gas phase it can cause odor and corrosion.

Desulfuration active carbon is widely used in flue gas desulfurization in thermal power plants, oil refining, petrochemical industry, chemical fiber industry, raw gas desulfurization in chemical fertilizer industry, gas desulfurization, natural gas desulfurization and other chemical industry.

We can provide two types of activated carbon for desulfurization:

Pellet Activated Carbon (PAC) Wet Adsorption. Water with concentrations of Hydrogen Sulfide below 1 mg/l , can be directly treated by coal pellet activated carbon.

Impregnated activated Carbons. Chemically impregnated carbons are typically coal based and impregnated with a caustic such as potassium hydroxide, sodium hydroxide or potassium iodide. The addition of an impregnate significantly increases the carbon’s Hydrogen Sulfide removal capacity. These carbons have Hydrogen Sulfide holding capacities of 20% to 25% by weight or about 3 to 4 times those of conventional activated carbon.

KeHuaYuan can provide pellet activated carbon and impregnated activated carbon to solve different conditions of H2S and other acid gases.
