How Do Absorption Towers Purify Waste Gas? Gas-Liquid Contact and Pollutant Removal Processes
Views:0
In an absorption tower, waste gas comes into full contact with a liquid absorbent, causing pollutants to transfer from the gas phase to the liquid phase or to undergo a chemical reaction with the absorbent. Waste gas enters the lower section of the tower and flows upward, while the absorbent is sprayed downward from the top, creating a counter-current contact pattern within the tower. Pollutants are either dissolved or chemically converted into the liquid phase; the purified gas then passes through a mist eliminator at the top of the tower—which minimizes the entrainment of liquid droplets—before being discharged. The absorption liquid, upon exiting the bottom of the tower, can be recirculated, replenished with additional reagents, or drained as waste, depending on specific operational requirements. The choice of absorbent, the gas-to-liquid ratio, and the circulation method must be determined based on the composition of the waste gas and the required treatment standards.
