Does carbon dioxide have an impact on the acid production process?
Thread Content
Acid is produced by the decomposition of sulfur-containing inorganic salts; the carbon dioxide concentration in the flue gas is relatively high. Some people say that this has an impact on acid production, but I’ve never heard of such a thing. Could anyone please provide an explanation? Thank you
The high heat capacity of CO2 results in a reduced temperature rise as observed.
In other words, it affects the conversion temperature; it should have little impact on the actual operations
Carbon dioxide has no direct effect on sulfuric acid production, but if the flue gas contains certain impurities in the conversion system (sorry, I’m not sure what those impurities are), such impurities can cause carbon dioxide to be reduced to carbon monoxide. Carbon monoxide then burns in the conversion system, leading to damage to the catalyst and consumption of oxygen. This is just my opinion; please feel free to correct me.
The problem is that the production of CO2 requires the consumption of O2, which reduces the oxygen-sulfur ratio and thus affects the conversion of SO2.
Are there any authoritative articles or statements that discuss this? Thank you
