Calcium Carbonate is a chemical compound having the chemical formula CaCO3. It is a white and insoluble powder-like substance that occurs naturally in minerals, marble, chalk, limestone, shells, calcite, pearl, and other related compounds. Medicinally, we use it as an antacid or a calcium supplement. It can also be used as cosmetics fillers.

The objective of a calcium carbonate looping (CCL) plant is to capture the CO 2 in the flue gas of the referenced plant before the gases are released to the surroundings through a stack. Initially, the CCL process is carried out in a small-scale laboratory to compare the performance of modified calcium carbonate sorbents.
