Carbon monoxide treatment When CO is the by product of certain reactions( burning of coal under limited air supply), how is it treated before releasing in the atmosphere or is it converted to some other form? Can that byproduct be used to synthesize some other compound ?
AFAIK, production scale processes are highly optimized, producing just traces of $\ce{CO}$. There traces are either not managed, or can by passed through catalyzators.
On the other hand, burning coke with limited air or oxygen $\ce{2 C(s) + O2(g) -&gt; 2 CO(s)}$ or passing water vapour through burning coke $\ce{C(s) + H2O(g) -&gt; CO(g) + H2(g)}$, are used intentionally, to produce $\ce{CO}$, eventually with hydrogen, for further synthesis.
