Sulfur dioxide oxidation
Thread Content
Why does sulfur dioxide enter the tower at the top and sulfur trioxide exit at the bottom during its catalytic oxidation? Seeking advice from experts
Because: 1. Gas flowing in from above and out from below is more stable, making short circuits less likely, just as with water which flows in from below and out from above； 2. Sulfur trioxide is heavier than sulfur dioxide
Isn’t it easier for gas to enter from below and exit from above, as gas naturally moves upward?
In fact, the main concern is the risk of carrying out catalyst powder, whereas this problem does not exist when going from top to bottom. If you think it makes sense, please vote for the best response: handshake
