Solving the problem of reformation S poisoning
Thread Content
What is the sulfur content in the gas phase after reformation sulfur poisoning? I remember reading that previously the sulfur content in the gas phase was three times that in the liquid phase. But in practice, after production under reduced temperature and pressure conditions, analysis after 24 hours showed that the sulfur content in the gas phase was more than 50 times that in the liquid phase (over 100 ppm in the gas phase, compared to 2–3 ppm in the liquid phase during sulfur poisoning). Could this be due to the release of sulfur from the catalyst, or is there an issue with the analytical methods? If more chlorine is added after S is poisoned, how many times is that usually the amount of chlorine added before?
Sulfur should have been removed; if possible, some new hydrogen can be introduced to replace it, and that will do. The sulfur content in the feed must be reduced; that’s necessary.
It was finally determined that it was an error in the laboratory analysis; it was just a false alarm
It can be analyzed using a portable analyzer
