① Oxygen content: The oxygen content requirement should be low to ensure safe production. High oxygen content leads to increased side reactions. Generally, it is required that the oxygen content in the gas should be less than 0.5%, the lower the better.

② Carbon dioxide: The amount of carbon dioxide is generally stable, but if the content is too high (such as desulfurization of gas), it will consume more sodium permanganate. Lowering the pH of the solution is not conducive to the absorption of hydrogen sulfide and has adverse effects on regeneration. Its content should be measured. As an adjustment

One of the criteria for reducing total alkalinity.

③ Gasification: Half water gas and coke oven gas contain gasification hydrogen, which generates gasification sodium and sodium hydrosulfide when in contact with alkaline solution, consuming alkali. Therefore, their content should be measured to adjust the alkalinity and estimate the consumption of residential materials Hydrogen sulfide: The content of hydrogen sulfide in different material gases varies greatly, and the production load depends on both the gas volume and the hydrogen sulfide content. The content scale value should be measured relatively to adjust the solution composition, regeneration situation, and operating conditions.

⑤ Organic sulfur: Generally, wet desulfurization can only remove a portion of organic sulfur, but it will be converted into hydrogen sulfide in the subsequent process transformation, which is also not conducive to production. Measuring the organic sulfur content can provide practical reference data for the desulfurization of sulfides in the subsequent process.
