Why does sulfur accumulate inside the injector?
Sulfur accumulation inside the injector is caused by improper design, manufacture, or installation of the injector, which results in the liquid flow rate not meeting the required levels, or it is due to the liquid being sprayed at the air intake of the injector.
Are there any other reasons? My injector doesn’t have any of the issues mentioned above; could it be related to the composition of the desulfurization liquid? Please explain in detail
It is related to the composition of the desulfurization solution; generally, when there are excessive unnecessary components in the solution, coupled with a high content of desulfurizing agents and an elevated level of adsorbed oxygen, it is more likely that premature regeneration occurs. When the desulfurization solution regenerates prematurely, the suspended sulfur in the rich solution does not float easily, while the lean solution becomes turbid, allowing sulfur to accumulate in the injectors. Over time, this can lead to blockages in the desulfurization tower, as well as an increase in pressure differences.
It is related to the composition of the desulfurization liquid; this issue occurred in our facility as well, and the problem disappeared after replacing the desulfurizing agent
It is crucial that the air intake capacity of the ejector is sufficient; an adequate amount of air flow ensures that sulfur buildup has no chance to remain on the ejector. Our ejectors have an air intake capacity of over 1:5, and sulfur buildup has never occurred in them. If regeneration is inadequate or the level of by-products is too high, sulfur accumulation inside the tower can occur; however, such problems can be avoided when the catalyst is appropriate and the air intake volume of the injector meets the required standards.
Conduct an analysis to determine the nature of S; it is generally related to low air intake volume, improper use of desulfurization agents, unstable internal air flow, and backflow of air. Conduct further investigations – as we are not aware of the specifics of your process, we cannot draw any conclusions rashly

Moderator, our injectors fail to generate sufficient pressure difference one after another; I’m not sure why the intake port isn’t drawing in air! Could you please help analyze it? Thank you! ! !
The injectors in our factory tend to accumulate sulfur; are there any good ways to address this issue?
I only know that if the injector doesn’t work properly, then regeneration won’t work properly, and desulfurization won’t work properly either. It’s similar here too. I’ve never really understood injectors! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
