When coal is burned, the sulfur combines with the oxygen in the combustion air to produce SO 2, which is emitted into the air through a plant's stacks, if not removed by a scrubber. Why does SO 2 need to be scrubbed? Sulfur dioxide is a reactive gas so when it meets other gases within the earth's atmosphere, a fine, secondary particle forms.

Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a secondgeneration carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
