Questions regarding oxygen concentration and sulfur dioxide concentration
Thread Content
In chemical reactions, 2 SO2 + O2 is sufficient to ensure a complete reaction. In actual production, the concentration of oxygen and that of sulfur dioxide are often in a 1:1 ratio; however, there are times when there is a lack of oxygen. For example, yesterday the oxygen concentration was 10.2 while the sulfur dioxide concentration was 9.8, which caused smoking. After adding more oxygen, the smoking stopped. I still don’t understand what the relationship should be in actual production. Seeking help – please avoid criticizing those who are new to this field
Are you referring to white smoke coming from the chimney?
This is a reversible reaction; to achieve a high SO2 conversion rate, an excess of O2 is necessary, and the equilibrium conversion rate depends on temperature and inlet conditions.
As of now, it has already doubled in quantity
The oxygen-sulfur ratio is important for the use of catalysts. Domestic catalysts require an oxygen-sulfur ratio of more than 1 for optimal reaction performance, while foreign catalysts need an oxygen-sulfur ratio of more than 0.9 in order to achieve a reaction rate sufficient for industrial use.
