Is it practically meaningful to maintain a stable liquid level in each dry absorption tank for production?
Thread Content
In actual production, there is a specified range for the liquid level in each dry absorption tank (assumed to be 40–75%). I wonder whether it’s better to keep the liquid levels in each tank as stable as possible and as consistent as possible, or whether it’s acceptable for them to fluctuate as long as they remain within that specified range Is it practically meaningful to maintain a stable liquid level in each dry absorption tank for production? Thank you for the guidance from the expert!
Of course, the more stable it is, the better. An excessively low level of liquid in the pump tank affects the actual head and flow rate of the circulating acid pump (submersible pump), which in turn impacts the control of process parameters. For submersible pumps equipped with intermediate bearings, the liquid level in the pump chamber must be strictly controlled; in recent times, at least 2 pump failures have been attributed to issues related to the control of the liquid level in the pump chamber.
When using a variable-frequency pump, is it necessary to install a flow meter to ensure the acid flow rate to the tower (in fact, it isn’t)?
The liquid level varies, which results in different amounts of acid in the tower (tank); with the same amount of water added, the acid concentration changes differently, affecting the stability of this concentration； Under the same frequency conversion condition, different liquid levels result in varying amounts of acid added, which in turn causes changes in the acid concentration within the system, thereby hindering its stable operation ； Therefore, it is generally required that the liquid level in the dry absorption section remain relatively stable, with minimal fluctuations and no sharp changes.
The three key elements for absorption: maintaining acid concentration, maintaining liquid level, and maintaining acid temperature. In this way, any abnormalities can be detected promptly.
The three key factors for absorption: acid concentration, liquid level, and acid temperature. Once these factors are stabilized, it is more favorable for the stability of absorption; generally, the more stable they are, the better. Maintaining an appropriate liquid level within a certain range is beneficial for improving absorption efficiency.
It’s not difficult to maintain stability; then why not strive to achieve it? Uniform liquid levels also contribute to accurate and fair calculation of production volumes for each shift
The acid concentration, temperature, and liquid level must all remain stable in order to identify problems promptly.
What is the general allowable range of variation?
