Abatement of particulate-laden SO ₂ in tapered bubble column with internals

Abstract

The performance of particulate-laden SO ₂ scrubbing in a modified tapered bubble column with internals is reported in this article. The presence of particles improved the particulate-laden SO ₂ removal efficiency to about 15% that was elucidated by the facilitated adsorptive mass transport. Experimentation revealed that nearly 100% removal efficiency of particulate-laden SO ₂ was achievable without any additives or pretreatment under certain operating condition of the scrubber. An empirical correlation was developed to predict the performance of the modified tapered scrubber. Experimental values fitted excellently well with the predicted values through the correlation (within ±5% deviation). The performance of the modified tapered bubble scrubber with column internals has been found to be better than a tapered bubble column without any internals.
