What exactly does gas desulfurization mean?
Thread Content
I would like to ask, in gas desulfurization by conversion, which gas is being transformed, and which gas turns into which other gas? Desulfurization – is it removing hydrogen sulfide? Thank you all for your advice, thank you. . !
CO+H2O=CO2+H2
CO2 gas is extracted through pressure swing adsorption or low-temperature methanol washing, while H2 is sent to the ammonia synthesis system for ammonia production
The transformed gas contains hydrogen sulfide, and this gas needs to be removed! What undergoes transformation is the active gas; CO and steam are converted into hydrogen and carbon dioxide.
It means exactly what it says: the gas that has been transformed is called transformed gas. This transformed gas needs to be purified before it can proceed to the next processing step, so that harmful gases such as hydrogen sulfide, which are not needed in subsequent steps, can be removed.

I wonder where the hydrogen sulfide gas comes from after the gas is transformed; I only see CO+H2O=CO2+H2, but no SO2
