Problem of COS removal from raw gas – solution required!
Thread Content
The raw gas passes through a complete shift converter (equipped with 21³ cobalt-molybdenum catalyst), and the level of COS at the outlet is even higher than that at the inlet. Could someone explain why this is the case?
Sir, could you be more detailed? The water vapor ratio is around 0.2
COS reacts with water vapor to produce H2S and CO2; an equilibrium exists. If there is insufficient water vapor, the levels of H2S and CO2 become too high. Low reaction temperatures may lead to the formation of COS under the action of catalysts, especially those containing iron and manganese
Oh, thank you! I’ve learned new knowledge:D
