    On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. SO 2 emissions and abatement. SO 2 emissions are dependent upon coal sulphur content, since virtually all coal-sulphur is oxidised to SO 2 during combustion (with some SO 3 formation). Power requirements and reagent utilisation within Flue Gas Desulphurisation (FGD) plants is therefore primarily dependent on coal sulphur content.

    Centrifuges are next, which subject the material to high centrifugal forces through high-speed rotation, forcing further separation of the coal from moisture. On ultra-fine material, moisture reduction is achieved via a filter press to lower the moisture content and produce a filter cake that allows for further solids handling of the material.
