What to do if the phenol content in the circulating oil is above the limit?

Where does the phenol in the circulating wash oil come from? What to do if it exceeds the limit? How to keep it from exceeding the limit?
Does no one know? I would be extremely grateful if some expert could give me some guidance~
Are you willing to carry out some technical upgrades for resource utilization?
How is it that no one knows? I’m confused; I don’t have any experience or theory in this area, do I?
Is the recovery of higher-grade phenols lower during naphthalene distillation?
We removed the naphthalene oil extraction side stream and only produce crude benzene. Previously, the tonnage of benzene consumed, the mass of benzene, and the mass of the washed oil were all good, but recently the phenol content has increased sharply, while at the same time it has also started to decline above 300 degrees. I’ve looked up a lot of information, and it all says to control the phenol content, but I don’t know how to do that How does the amount of phenol increase? Is the decrease before 300 degrees caused by an increase in phenol? Thank you very much for your reply; I hope to get your help!
