SO2 Scrubber – Wet Scrubbers

A SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber …

Sulfur Dioxide Scrubber: pH Control

The SO 2 within the scrubbing gases can be controlled by maintaining the level of caustic scrubbing chemicals that are commonly used. pH is a critical factor for proper operation of a scrubber. It is also difficult to measure due to 2-15% solids and tendencies towards scaling, coating and plugging.

The Chemical Aspect of NOx Scrubbing

NO2 gas has fairly high solubility and reactivity to water and in aqueous solutions or alkalis as compared with NO, and can be removed by wet scrubbing. On the other hand, gaseous NO is only slightly soluble in water and is not very reactive with typical aqueous solutions. Nitric oxide does react with oxygen as follows: 2NO+O2 = 2NO2

SO2 scrubbing with NaOH aquas solution | Physics Forums

The 'ppm' (Parts Per Million) of SO2 in the exhaust flue gas is 5.26. But, the allowable ppm for SO2 is below 5 ppm. I don't know in what ratio we need to mix the water and NaOH for scrubbing the SO2 from this exhaust flue gas. If you are already at 5.26 ppm, and you want <5 ppm, you are pretty close.
