Problems with the refining tower in polypropylene plants
Thread Content
In the molecular sieve tower of the double-loop pipe polypropylene plant, the temperature at the top is about 10 degrees lower than that in the middle and lower sections. Could someone please help explain this? It refers to the secondary drying tower. Thank you
:) Generally, heat is generated during the adsorption by molecular sieves. So your question is hard to explain ； Ask the experienced teachers at your facility. I have the answer, let me know
It can’t be the case of an internal leak at the top of the flare, right? You can check the process. Also, is there a problem with your temperature sensor, or is the installation location incorrect? Let’s give it a repair
The adsorption of water by molecular sieves generates heat, but in a tower the temperature difference isn’t that large; it’s at most about 1 degree. I think there’s a problem with the thermocouples – you should check them. Internal leakage at the top should not cause any problems, unless it’s a static tank
