Calcium Looping Process - an overview ScienceDirect Topics

The calcium looping process removes CO2 from flue gas at 675 C 1250 F by carbonating calcium oxide CaO to calcium carbonate CaCO 3 through the following reversible reaction CaO CO 2 = CaCO 3 The captured CO 2 is released at 925 C 1700 F by calcining the CaCO 3, the heat being provided by the oxy-combustion of coal.

Calcium Bicarbonate - an overview ScienceDirect Topics

Carbonation is the process in which the alkaline calcium hydroxide Ca OH 2 in the concrete reacts with carbon dioxide CO 2 to produce calcium carbonate CaCO 3 and also a limited amount of calcium bicarbonate within the concrete matrix Hunkeler, 2005 . The reaction is at least a two-step process: 2.6 CO 2 H 2 O ⇔ H 2 CO 3

Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water. Calcium carbonate crystals are referred to as calcite.

Calcium carbonate - Wikipedia

Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid , but excessive consumption can be hazardous and cause poor digestion.
