A process for CO2 capture and brine salinity reduction through reaction with potassium hydroxide: A multi-stage evaluation

Study on the removal of SO42−and Ca2+from potassium chloride brineviaa method combining calcium chloride and carbon dioxide

“…The absorption of carbon dioxide can significantly be accelerated by forming carbonate ions in highly alkaline solutions. 25 The equation is as follows.2OH − + CO 2 (aq) ↔ CO 3 2− (aq) + H 2 O…”
