Process water is used to cool the sulfur trioxide vapor to cause it to condense. What medium flows through the shell and tube sides? Then, for condensers like this, is it also important that the fluids in both the tube side and the shell side be in a turbulent state? Please help answer it~ I’ve been stuck here for a long time
Sulfur trioxide vapor with moisture flows in the tube side, while the opposite is true for the shell side.
Undoubtedly, the cooling water flows through the shell side, while the condensed gas flows through the tube side – this is the case both in terms of the material requirements for the condenser and from a heat transfer perspective.
Water flows through the tube side; the shell is not under pressure, which extends the equipment’s service life and reduces manufacturing costs
The coolant water flows through the tube side, while sulfur trioxide vapor flows through the shell side.
Here, the issue of corrosion is the main concern: sulfur trioxide contains a certain amount of water, which leads to the formation of acid; hence, its corrosiveness is relatively high. Therefore, it should be handled in the tube side, and corrosion needs to be taken into account in that case. If sulfur trioxide flows in the shell side, then corrosion must be taken into account for the entire equipment, including both the tube side and the shell side; as a result, the material required for the equipment becomes more expensive, and the investment costs increase significantly. Conclusion: Sulfur trioxide flows in the tube side, while water flows in the shell side.
The shell side is clean and less prone to scaling; conversely, the tube side is more difficult to clean
