What is the purpose of the oxygen content analyzer located after the oxidation tower in the alkali solution regeneration process of the refining system?
I don’t have this gauge here; is it used to monitor the deoxygenation effect?
I think it’s because of the oxygen consumption associated with the regeneration reaction
It is necessary to ensure the proper progression of the alkaline oxidation reaction, so that all sodium thiolates are oxidized to disulfides rather than sulfur; therefore, it is required to analyze the oxygen content in the exhaust gases in real time in order to maintain a certain excess level.
It’s as if the eyes are affected; the presence of excess oxygen means that everything is converted into disulfides. So, if the amount of excess oxygen is too high, what is the chemical formula for sulfur?
If there is an excessive amount of excess oxygen, it is unsafe, as it has a significant impact on the exhaust gas treatment process, and it also results in high energy consumption. Sulfur is elemental S; if there is a small amount of NaS in an alkaline solution and the oxygen level is insufficient, it will be oxidized to elemental S.
