process of turning flue gas into calcium bicarbonate

Water hardness

By adding calcium chloride CaCl 2 into water, we artificially increase its hardness. As mentioned above, CaCl 2 causes permanent (i.e. unremovable by boiling) water hardness. And the first part of the experiment demonstrated this fact: with boiling, no noticeable precipitation occurs on the walls.

grinding sodium bicarbonate

The kinetics of neutralization can be increased by grinding sodium bicarbonate to a speci-fic particle size, using a determined contact time and controlling the temperature of flue gases (between 150C and 400C). When sodium bicarbonate is injected into hot flue gas, it turns into activated sodium carbonate with a higher specific surface area.

Sodium bicarbonate

Sodium bicarbonate reacts spontaneously with acids, releasing CO 2 gas as a reaction product. It is commonly used to neutralize unwanted acid solutions or acid spills in chemical laboratories.

Soda lime is a solid off-white mixture of calcium and sodium hydroxides used in scuba rebreathers, submarines, anesthesia, and other closed breathing environments to prevent the poisonous accumulation of CO2 gas. The mixture acts as a sorbent (a substance that collects other molecules), turning into calcium carbonate (limestone) as it amasses CO2.
