process of turning flue gas into calcium bicarbonate

SIMULATION STUDY OF PRODUCING NH4HCO3 FROM THE FLUE GASES

This simulation methodology being pioneer in Pakistan can produce ammonium bicarbonate (NH4HCO3) a fertilizer from the flue gases of brick kilns that does not contaminate the underground water. This technology if implemented can also generate 31331 tons carbon credits per year from the flue gases of brick kiln, a step towards sustainability.

Limewater Wikipedia

Limewater is the common name for a dilute aqueous solution of calcium hydroxide.Calcium hydroxide, Ca(OH) 2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste.

Carbon Capture Journal

With their carbon-capture method, flue gas is bubbled through the solution, causing CO2 molecules to stick to the BIG sorbent and crystallize into a sort of organic limestone. This solid can then be filtered out of the solution and heated at 120 degrees C to release the CO2 so it can be sent to permanent storage.

Carbonation Simple English Wikipedia, the free encyclopedia

When rain passes through the atmosphere, it takes in or mixes with carbon dioxide, turning it into a weak carbonic acid.When the rain falls in limestone, it dissolves the calcium carbonate in the rock, turning it into calcium bicarbonate and taking it away. Holes and large cracks can form in the rock. Such a place is called karst.If a stream or river passes through it, it could be swallowed up
