Question: Why are absorption towers needed? What is the absorbent in the absorption tower? Answer: The function of the absorption tower is to absorb hydrogen sulfide from the exhaust gases, ensuring that the SO2 emissions meet the **allowed emission standards. At the same time, it allows hydrogen sulfide to be recovered, thereby increasing the sulfur recovery rate of the facility. The absorption tower uses a 30–50% methyl diethanolamine solution as the absorbent.

Since the lean gas contains gasoline components, it is necessary to use a reabsorbent in the reabsorption tower to absorb these components, thereby increasing the yield of gasoline and reducing oil contamination in the dry gas. Diesel is used as the reabsorbent in the reabsorption tower.
The absorption tower is the equipment used to carry out absorption operations. They are classified into three categories based on the gas-liquid phase contact pattern. The first category includes plate towers, bubble absorption towers, and stirred tank bubble absorption towers, in which the gas is dispersed in the liquid phase in the form of bubbles ； The second category consists of ejectors, venturi tubes, and spray towers in which the liquid is dispersed in the gas phase as droplets ； The third category consists of packed absorption towers and falling film absorption towers, in which the liquid comes into contact with the gas phase in a film-like manner. Light diesel is used as the absorbent.
The function of the scrubber is to absorb hydrogen sulfide from the exhaust gases, ensuring that the SO2 emissions meet the specified standards; at the same time, hydrogen sulfide is recovered and reused, thereby increasing the sulfur recovery rate of the facility. The absorption tower uses a 30-50% methyldiethanolamine solution as the absorbent.
