Operation of the converted foam combination tower
Thread Content
The conversion foam combined tower has been overhauled several times in our company; it deforms due to high temperatures, which increases its resistance
Don’t your foam towers have temperature measurement points to control the temperature? The only solutions are: 1. Increase the water inflow, 2. Reduce the HCL content in the mixture, 3. Replace it with a larger foam tower that is suitable for the production capacity. Also, when there is an excessive amount of temporary HCL, the water inflow can be reduced or stopped, while increasing the water flow to the subsequent washing towers. It’s necessary to find a way to handle things flexibly based on the actual circumstances.
Thank you. I’ve learned it. When there is an excessive amount of HCL temporarily, can we reduce the water flow or even stop it? Is that possible?
The 2nd floor is conditional and only temporary. First, the temperature of the foam tower rises sharply; as a compromise measure to prevent the tower trays from collapsing due to excessive temperatures, it is also necessary to increase the water flow rate in the wash tower. During this period, it is also necessary to monitor the temperature of the alkali scrubber to ensure that subsequent equipment is not exposed to acid. In any case, it is essential to reduce the HCL content (or, in other cases, the total amount) to address the issue fundamentally.

Preventing high-temperature tower damage during startup and shutdown: Adjust the valves to reduce air intake, decrease water supply, or shut it off. Pay close attention to the temperature measurement in the bubble section; once it stabilizes, adjust it back to normal. Material: If the tray is made of FRP, it generally will not deform even at 100 degrees for a short period of time. The bubble cap CPVC material is also fine. The reason for high air resistance could be that the packing section is blocked, or the overflow weir of the bubble cap tray is set too high; if there is packing for foam removal in the upper part of the tower, it might be blocked as well.
