WebS (s) + O2(g) → SO2(g) This sulfur dioxide then dissolves in droplets of rainwater to form sulfuric acid: H2SO4. When fuels are burned in vehicle engines, high temperatures are … Most FGD systems employ two stages: one for fly ash removal and the other for SO2 removal. Attempts have been made to remove both the fly ash and SO2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an e…
WebThe sulphur oxides of shipping exhausts typically consist of ~95% sulphur dioxide, SO 2 and the remaining ~5% of sulphur trioxide, SO 3. When dissolved, a reaction occurs whereby the sulphur dioxide is ionised to bisulphite and sulphite, which is then readily oxidized to sulphate in seawater containing oxygen [1].
