What is the relationship between sulfur dioxide conversion rate and exhaust gas emissions in sulfuric acid production?
Thread Content
What impact does the conversion rate of sulfur dioxide have on the sulfur dioxide content in the exhaust gases? Are there any corresponding calculation formulas or curves for the two?
A high conversion rate of sulfur dioxide means a low level of sulfur dioxide in the exhaust gases
QS02 = 2.86 V exhaust C2 (1) Q sulfuric acid mist = V exhaust C3 × 10-6 (2) V exhaust = 228.57(1 – 1.5C1x) / (C1x a) Where: QS02 ———— emission of sulfur dioxide in exhaust, kg/t of sulfuric acid； Q Sulfuric acid mist —— Emissions of sulfuric acid mist (industrial/mining SO3) in exhaust gases, kg/t of sulfuric acid ； C1————Sulfur dioxide concentration in the converter, % ； C2————Sulfur dioxide concentration in exhaust gases, % ； C3————Sulfuric acid mist content in the exhaust gases, mg/Nm3; x————Total conversion rate of sulfur dioxide, % ； a————Total absorption rate of sulfur trioxide, % ； V is the volume of exhaust gas emitted per unit of sulfuric acid produced, in Nm3/t of sulfuric acid.
