Friends, what is the relationship between the hydrogen sulfide content in gas and the sulfur dioxide content in flue gas? Ignoring furnace leakage.
Based on an oxygen content of 3.5% in the flue gas after combustion, the theoretical oxygen demand and air volume are calculated, followed by the volume ratio before and after combustion; the calculation is done assuming that hydrogen sulfide is completely converted into sulfur dioxide
According to the law of conservation of mass, the mass of sulfur remains unchanged before and after.
Based on the molecular weight, it can be estimated that 34:64 is approximately a 2:1 ratio
The volume remains unchanged before and after combustion
Is it the emission value? If it is based on 20 mg/m3 of hydrogen sulfide, and sulfur dioxide equivalent to dry basis is about 3.5 mg/m3, then if the total sulfur level is 200, it will definitely be below 50, so it does not exceed the limit. I calculated it; it may not be accurate.
2H₂S+3O₂=2SO₂+2H₂O
Calculated based on the chemical reaction equation
