Circulating fluid replacement cycle of the absorption tower
Thread Content
The spray towers we use currently employ water for absorption processes. After being in use for a while, the water may reach a state of relative saturation, at which point the treatment efficiency **decreases. The key question is: how can we determine when it’s time to replace the absorption water? Replacing it regularly in this way will yield better results.
Determine the replacement amount based on the amount of pollutants removed and the concentration of the circulating fluid!
We are engaged in wastewater evaporation – let’s communicate more!
Usually, there is already a slight excess of water, and the excess water overflows from the lower water seal.
Normal operation is controlled in this way; I’m just wondering if there are any calculation methods or other information available to determine how often the circulating absorbent liquid needs to be replaced. This makes it easier to control
In your case, I think it’s necessary to use a certain value as a criterion for making a decision – such as the pH or density of the water, or other parameters. When these parameters reach a certain level, it’s necessary to remove some of the water and add fresh water in its place
It can be calculated using the phase equilibrium equations of the absorption process
I think the same, but I don’t know where to start with the calculations. Relying on post-production testing is also not practical.
This formula is used during the design phase, but calculating the replacement cycle proves to be rather difficult.
Calculations are only a guide; practice is what truly matters. Since it’s already in operation, it’s better to directly test at which points liquid should be drained
The key point is that we cannot conduct the testing ourselves; we need to turn to professional testing companies, and the costs are relatively high.
