What are the main differences between the sulfur-containing wastewater from atmospheric and vacuum distillation units and that from catalytic cracking units?
Thread Content
I seek help from experts among my colleagues from Sichuan: What are the main differences between the sulfur-containing wastewater from atmospheric and vacuum distillation units and that from catalytic cracking units? I looked up some information but couldn’t find an exact explanation for the system
The hydrogen sulfide and ammonia nitrogen concentrations in the atmospheric and vacuum distillation sulfur-containing wastewater are lower than those in the catalytic sulfur-containing wastewater.
I’m not quite sure what you want to know – whether it’s the sulfur content or the properties of the wastewater. The sulfur content is influenced by the amount of sulfur in the raw materials as well as the efficiency of the desulfurization system； There are also differences in the concentration and composition of organic matter in wastewater.
It’s not limited to the sulfur content; it’s the nature of the wastewater
I’m a bit puzzled by this as well. What I understood at the time was that the sulfur-containing wastewater from atmospheric and vacuum distillation contained organic substances with sulfur elements, while the sulfur-containing wastewater from cracking contained hydrogen sulfide. I’m not sure if this is correct; it’s just for reference!

The sulfur-containing wastewater from catalytic units contains high levels of hydrogen sulfide, phenols, and ammonia nitrogen, while the sulfur-containing wastewater from atmospheric and vacuum distillation units tends to emulsify and contain oil.
