How should a rotary extractor tower for phenol-ammonia recovery be controlled to ensure that the phenol content in the phenol-containing water is within the specified limits?
The rotary disk extraction tower is primarily used for extracting monophenols and polyphenols from dilute phenol-containing aqueous solutions. By properly controlling parameters such as the temperature of the feed stream, the rotation speed of the rotary disk, and the phase interface, it is possible to extract the phenols more effectively, ensuring that the effluent meets the required standards.
It is important to control the extraction temperature, pressure, rotation speed of the rotor, and the amount of ether used. The pH of the feed material is also crucial; this depends on the operating conditions of the previous tower.
Original poster, may I ask a question about an extraction tower? Are the rotating disks of a rotary extractor tower smooth on both the upper and lower surfaces? Is it sufficient for the shear force generated by the rotation of the turntable to ensure thorough contact between the materials?
Sulzer possesses technology for phenol recovery rotary towers
I’ve heard of it for the first time; I’m not sure if it’s used in phenol recovery units Actually, it seems that the limitation of current phenol recovery units does not lie in the rotary disk extraction tower.
Some points were already mentioned in the earlier sections; I’d like to add a few more: 1. The speed of the rotating disk also has a significant impact on the extraction efficiency – uneven mixing leads to poor extraction results. 2. The upstream system needs to ensure that the water flow is within an appropriate range. 3. It would be better to use a more advanced extraction technique; why use a rotating disk? It’s difficult to control, causes uneven mixing, and the short residence time of the materials also affects the efficiency of extraction and separation.
