Extractive distillation
Thread Content
I work in UOP extraction distillation and hope to exchange ideas with everyone
Do you have any experience in dealing with leaks in stripping steam evaporators?
Tube bundle leakage is causing the evaporator liquid level to keep rising
Is there a bypass? If so, it can be switched on to use 0.35 pressure steam in place of the stripping steam
We use 2.2 MPa steam after temperature and pressure reduction from 3.5 MPa; the reboiler is made of duplex stainless steel
Can it be cut out? After cutting it, separate the floating head to find the leaking one and seal it off separately
Thank you all. The preliminary investigation showed that there was a problem with the material used for the tubes at the time of equipment procurement; the extraction and stripping steam reboiler provided by UOP has side lines that can be disconnected
