A well-maintained wet scrubber can absorb what percentage of SO2 in the flue gas?

A well-maintained wet scrubber is highly effective at removing sulfur dioxide (SO2) from flue gases. These systems utilize a liquid, typically water or a neutralizing solution, to absorb pollutants. The correct percentage of SO2 absorption that a wet scrubber can achieve is around 90% under optimal operational conditions.

This level of efficiency is due to the design and function of the wet scrubber, which allows for greater interaction between the flue gas and the absorbent liquid. Factors such as the type of scrubber, the flow rates, and the chemical properties of the absorbent can influence performance, but a 90% removal rate is a common benchmark in the industry.

While options indicating lower percentages might suggest less effective systems, established technology can reliably achieve high absorption efficiencies, reaffirming that a properly maintained wet scrubber can reach up to 90% in removing SO2 from flue gas emissions.
