Basic requirements for desulfurization equipment

Desulfurization equipment generally refers to a series of equipment used in the power industry to remove sulfur from coal and prevent SO2 from being generated during combustion. Sulfur pollution to the environment is relatively large, sulfur oxides and hydrogen sulfide pollution to the atmosphere, sulfate, hydrogen sulfide pollution of water bodies, is currently the focus of environmental protection work. In the production process of thermal power plants, a large amount of coal is burned, and coal often contains a certain amount of sulfur. After burning, these sulfur elements will release a large amount of SO2, which will cause great harm to the environment if not treated. Therefore, the current power industry generally uses desulfurization equipment.

So, what are the requirements for actual production of desulfurization equipment?

1. Oxygen content: The oxygen content is required to be small to ensure safe production. The oxygen content is high and the side reaction is increased. Generally, the oxygen content in the gas should be less than 0.5%, and the lower the better.

2. Carbon dioxide: The carbon dioxide content is generally stable. If the content is too high (such as shifting gas desulfurization, etc.), more sodium carbonate will be consumed. Decreasing the pH of the solution is not conducive to the absorption of hydrogen sulfide and has an adverse effect on regeneration. The content should be measured. As one of the basis for adjusting the total alkalinity.

3. Cyanide: The semi-water gas and coke oven gas contain hydrogen cyanide. When contacted with the alkali solution, sodium cyanide and sodium hydrosulfide are formed to consume alkali. Therefore, the content should be measured to adjust the alkalinity and predict the consumption of raw materials.

4. Hydrogen sulfide: The content of hydrogen sulfide in different raw materials varies greatly. The size of the production load depends on the amount of gas on the one hand and the hydrogen sulfide content on the other hand. The content range should be accurately measured to adjust Solution components, regeneration conditions, operating conditions, etc.

5. Organic sulfur: Generally, wet desulfurization can only remove part of organic sulfur, but it will be converted into hydrogen sulfide in the later process transformation, which is also unfavorable for production. The determination of organic sulfur content can provide desulfurization for subsequent process sulfides. Real reference data
