If the catalyst appears red to the naked eye, what does that usually indicate? This phenomenon can occur in some situations
It indicates the presence of iron; iron oxide is red
Catalyst iron poisoning causes the catalyst to turn red. We have experienced catalyst iron poisoning before, due to excessive sulfur content in the raw materials, which accelerated corrosion in the atmospheric and vacuum distillation systems and led to a large amount of iron entering the catalyst.
Use the catalyst as a indicator for heavy metals; if the iron level is high, replace the balance agent as soon as possible.
It is iron poisoning; in the case of a vacuum distillation unit, it’s as mentioned on the third floor. If there is a fractionation tower for distinguishing between light and heavy components, check whether the electrodesalination process was not effective enough, or consider changing the type of demulsifier
That makes a lot of sense; if possible, conducting a metal analysis or element analysis and comparing it with that of the new agent will give an approximate idea.
We experienced the same situation a few days ago: the catalyst became poisoned, which caused a drop in our yield. After replacing the catalyst, the situation improved significantly, and this is mainly related to the metal content in the raw materials!
