Lime Processes – Alpha Thermal Process
Lime Processes. The dissociation of limestone (calcium carbonate) into quicklime and carbon dioxide at temperature is a process known as calcination i.e., CaCO 3 = CaO + CO 2 ΔH = -760 BTU/lb CaCO 3. Magnesium Carbonate, which is found in some quantities with limestone deposits, also dissociates according to the reaction: MgCO 3 = MgO + CO 2

What is soda lime and its formula?
Soda-lime is a granular solid produced by slacking quicklime (CaO) with a concentrated solution of sodium hydroxide, NaOH (aq). In chemical reactions, soda-lime acts as sodium hydroxide but, unlike sodium hydroxide, it is not deliquescent and does not attack glass. Soda lime reacts with CO2 being respired by the organisms in the soil.

Drgersorb 800+ – Soda Lime
Thanks to its unique pellet form, Drgersorb 800+ does not undergo channel formation. Our soda lime absorbs CO 2 evenly and is effectively utilized. Its pellet form and high porosity create an optimal surface. Drgersorb 800+ is therefore able to absorb more CO 2 and lasts longer than conventional soda lime.
