Sulfur poisoning of ammonia synthesis catalysts is a permanent form of poisoning, and its activity cannot be restored.

Boss, sulfur poisoning is permanent!

Permanent poisoning, irreversible! Where does this S come from?

Introducing sulfur into the synthesis tower is a major no-no in ammonia synthesis. In addition to the desulfurization system, the decarburization system can also absorb some inorganic sulfur, and there are also precision desulfurization tanks. Could problems have occurred simultaneously?

Then it’s completely useless; whereas CO and CO2 can still be restored in a short period of time.....

Ammonia synthesis catalysts are extremely sensitive to hydrogen sulfide; it should have been completely removed earlier
