ABSTRACT
Because sulfuric acid mist and fine particulates such as PM2.5 are difficult to capture in typical dry electrostatic
precipitators (ESPs), using a wet ESP is a viable option for the control of sulfuric acid mist and fine
particulates in a flue gas. In this study, bench-scale tests were first conducted to find acceptable methods for
achieving uniform water distribution and effective discharge. Based on the bench-scale results, a pilot-scale
wESP was designed and constructed. The pilot-scale wESP demonstrated good performance on the removal
of sulfuric acid mist and fine particulates.
