Calcium Oxide (CaO) is commonly referred to as quicklime. Calcium Oxide is a high Calcium derivative of Calcium Carbonate, or limestone. Calcium Oxide is produced by heating Calcium Carbonate to very high temperatures, which causes the Carbon Dioxide to separate as gas from the Calcium Carbonate.
CaCO3 + HEAT → CaO + CO2
Hydrated Lime (Calcium Hydroxide) (Ca(OH)2), or slaked Lime, is an inorganic mineral compound mined from the Earth. To form Hydrated Lime, Calcium Oxide (CaO) reacts with water to form a white powder, containing less than 1% moisture.
CaO + H2O → Ca(OH)2
Both Pebble and Hydrated Lime come in many different sizes and grades, and can be used for many different processes including water treatment, flue gas desulfurization, construction, chemical manufacturing and industrial applications.
W.K. Merriman can provide Pebble and Hydrated Lime at different production points throughout the United States. Our quality processes are carefully monitored, and we are able to supply multiple grades of Lime that meet and NSF-60 standards.
