Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature . The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium ...

The process is known as basic because fluxes of calcium oxide or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter. [2] The process was invented in 1948 by Swiss engineer Robert Durrer and commercialized in 1952–1953 by the Austrian steelmaking company VOEST and ÖAMG.
Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. [1] It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
For about one hour late Friday, day-ahead prices on ERCOT's website jumped as high as $688 per MWh. Texas power prices briefly soar 1,600% as a spring heat wave is expected to drive record demand ...
First calcium oxide (lime) is produced from calcium carbonate (limestone or chalk) by calcination at temperatures above 825 °C (1,517 °F) for about 10 hours at atmospheric pressure: + The calcium oxide is then spent (slaked) by mixing it with water to make slaked lime (calcium hydroxide):
