Is the sampling ratio for the sulfur content in the high-exchange reaction effluent lower than that for the sulfur content in the light fraction oil?

Why is the sulfur content in the samples taken from the high-temperature exchange reaction effluent lower than that in the low-temp fractionated oil? For sampling at high temperatures, the drain blind cap was removed – could it be that the sulfur evaporates along with the oil and gas at high temperatures? I would like to ask the seniors for advice
I don’t think so. Are you working with hydrogen sulfide or organic sulfur? Organic sulfur does not evaporate
The content of different sulfur types in the boiling points of various components varies, which may be related to the composition of the sulfur. This is what I think, but my skills are also just average; I suggest you keep seeking advice from those more skilled, and let me know once it’s done
I believe that when sampling at high temperatures and then reducing the pressure of the oil, hydrogen sulfide evaporates, and most of the hydrogen sulfide in the lower fraction is removed, though some remains dissolved.
The analysis on the 5th floor makes sense. The key point is that leaks in the heat exchangers located in high-pressure areas can only occur from high pressure to low pressure; therefore, temperature is the determining factor for sulfur content. Moreover, at lower temperatures, all the sulfur that can vaporize does so, and what remains is sulfur that is difficult to vaporize or is dissolved in ammonium salts and thus not easy to vaporize；
