The emission of SO 2 from various chemical industries is associated with particulate (fly‐ash), mostly concentrations of particulate laden sulfur dioxide in and around these plants overshoot the danger point. Prediction of fly‐ash laden SO 2 removal efficiency is very important for the selection of pollution control equipment. Experimental investigations were conducted on the scrubbing of fly‐ash laden SO 2 in the modified multistage bubble column scrubber using water. Experimental results show that almost zero penetration (100% removal efficiency) of fly‐ash laden SO 2 can be achieved in this system. A correlation was developed for predicting the percentage collection efficiency of sulfur dioxide in the presence of fly‐ash. Experimental results agreed excellently with the correlation. Enhancement of SO 2 collection due to the presence of fly‐ash was also quantified.
