Thiamine saturator accident

Thread Content

A few days ago, during operation of the saturator, an accident occurred in which mother liquor was spilled from the full-flow tank. What could be the causes of this? Thank you

1. Check the central tube; generally, it can withstand a pressure of 30,000, so verify whether there are any leaks in the central tube. 2. Has the color of the mother liquor turned black? Is there an increase in tar foam, and has the density of the mother liquor decreased, resulting in the liquid surface not being able to be covered? 3. Check the acidity of the mother liquor!

The lower liquid pipe is likely to leak.

It might be due to a leak in the liquid discharge pipe, or pressure buildup caused by blockages in subsequent sections

1. Check whether there is any blockage in the upstream and downstream sections, especially in the final cooling tower. 2. Check whether the nozzle of the small mother liquor pump has fallen off, resulting in excessive replenishment of liquid and an excessively high liquid level in the absorption chamber of the saturator. 3. Is the downcomer in the crystallization chamber of the saturator blocked? 4. Is the full-flow tube corroded, causing leakage and preventing effective sealing of the gas? 5. Excessive addition of acid caused the mother liquor to overheat. 6. Human error and excessive fluid replenishment time led to an excessively high liquid level in the saturator. 7. Check all the water supply valves that may feed into the saturator. 8. The crystallization pump does not produce a sufficient amount of output in a short period of time. Furthermore, I disagree with the view expressed on the first floor; although a high amount of tar can reduce the specific gravity of the mother liquor, it does not cause this phenomenon. Typically, the effective height of a full-flow tank is a little over 3 meters but less than 4 meters. If it were water, a pressure of over 30,000 units could be maintained, but even with a large amount of tar, the specific gravity of the mother liquor remains higher than that of water, so the pressure before the saturator will not be able to break through the water seal.
