Why, in the methanol distillation process, when the ammonia removal tower is not regenerated properly, does trimethylamine fail to meet the specifications along with potassium permanganate as well?

The overhead product from the methanol distillation unit in our workshop is sent to an ammonia removal tower to have trimethylamine removed from it; however, after regenerating the adsorption resin in this tower once, the trimethylamine content increased by hundreds of times, resulting in failed test results for the potassium permanganate test as well. I would like to ask the experts: what are the reducing substances present at this time?
The high-concentration trimethylamine that was separated entered the methanol. It is up to you to determine where this high-concentration trimethylamine is hiding; it’s possible that the separation solution was not completely drained after the separation process.
