In this work, the utilization of iron(II) hydroxide (Fe(OH)(2)) slurry as the absorbent in wet flue gas desulfurization was investigated. The most important reason for selecting Fe(OH)(2) is that iron sulfate, formed by captured sulfur dioxide, can be converted back to Fe(OH)(2). First, in the experiments, a bubble column was used with continuous gas and liquid flow. Second, perforated plates were used in the same column. Lastly, a magnetic field was applied to this multiplate bubble column so that the flow of Fe(OH)(2) slurry could be affected by the magnetic field because of the electric charge of Fe2+. It was found that the multiplate bubble column performed better than the single-stage bubble column, and application of the magnetic field further enhanced the absorption efficiency.
