Changes in hydrogen sulfide content after the ammonia-based desulfurization tower in coking plants

Sampling after the desulfurization tower (zinc-ammonium complex solution): Comparison of hydrogen sulfide levels in gas with and without desulfurization solution; reasons for the increase in hydrogen sulfide content in gas after desulfurization
The same is true in our factory: desulfurization takes place before the fan, and after passing through the fan, the material goes on to ammonium sulfate and benzene extraction. The analysis shows that the hydrogen sulfide level at the exit of the benzene extraction process is about 30% higher than that at the fan’s exit. What could be the reason for this?
