Not sure where to post this, C02 removal
« on: October 01, 2015, 01:29:16 AM »
I was just wondering if anyone had any knowledge or ideas about how one would go about removing absorbed C02 from

Soda lime( The main components of soda lime are

Calcium hydroxide, Ca(OH)2 (about 75%)
Water, H2O (about 20%)
Sodium hydroxide, NaOH (about 3%)
Potassium hydroxide, KOH (about 1%).

without compromising the Soda lime?

Im a amateur if you can tell haha

Depends what you mean by compromising.

Sodalime and quicklime (CaO) absorbs carbon dioxide by forming limestone (calcium carbonate CaCO3). CO2 can be removed from limestone by heating it to around 900 °C resulting in quicklime. After that quicklime can be hydrated to sodalime by adding water.
Chemists do it periodically on table.

By compromising i mean having the Sodalime still in the good condition to what is was before absorbing the CO2 after it has been extracted from it. 

so Sodalime absorbtion of CO2, CO2 extracted from Sodalime, Sodalime left to its original form.

The only approach I can think of is to roast and slake, no idea if you would consider the lime after these two operations "uncompromised".
