This regenerates the base and forms solid calcium carbonate (CaCO 3), which is precipitated out of the base solution. The precipitate is then sent to a calciner, where it is reacted at very high temperatures (about 800°C) with oxygen (O 2) from an air-separation unit, forming pure CO 2 and calcium oxide (CaO).
