- Calcium oxide (CaO),
commonly known as burnt lime, lime or quicklime, is a widely used
chemical compound. It is a white, caustic and alkaline crystalline
solid. As a commercial product lime often also contains magnesium oxide,
silicon oxide and smaller amounts of aluminium oxide and iron
oxide.
- Calcium oxide is a
crystalline solid. Its crystal structure is Isometric with space group
Fm3m. It is generally unstable when 553 moisture is present and exhibits
a large exothermic reaction with water to form aqueous
Ca(OH)2.
- Calcium oxide
is produced by heating calcium carbonate to 2000 deg F where carbon
dioxide disassociates as a gas from the calcium carbonate.
- CaO is
representative of group II oxides (MgO, SrO, etc). It can be prepared by
intense roasting of the corresponding carbonate or hydroxide. The
formation is reversible in the presence of CO2 or H2O,
respectively.
- Lime processes
mainly contains the following basic steps: Winning of limestone ,
Limestone storage and preparation , Fuels storage and preparation ,
Calcination of limestone , Quicklime processing , Quicklime hydration
and slaking , Storage, handling and transport .
- More than 90% of the
lime (burned or hydrated) produced in the United States is used for
basic or industrial chemistry. 70 The primary use is for steel
manufacture (30%), metallurgy, air pollution control and water and
sewage wastewater 71 treatment (24%), cement and mortar, chemical
manufacture, manufacture of glass and paper, diluents and carriers of 72
pesticides such as lime-sulfur and Bordeaux mixture, and bleach
production and other chemical manufacture.
- Lime typically sells
for A$100 to A$120 per tonne implying a total value of production of
$80m. Import competition largely decides the price of lime.
- The lime industry is
a captive industry to Western Australia. Lime producers are competitive
through ready access to limestone, cheap energy, economies of scale and
in particular by international freight that acts as a barrier to trade
in both directions for this low value product. Though import competition
serves mainly to determine local prices, it is possible if not probable,
that the quality of lime produced in Western Australia will increase
with increasing demand from resource companies especially those close to
north western ports where import competition is inevitably greatest and
with the future supply of higher grade lime from Swan Portland
Cement.
- Like other calcium
compounds, calcium oxide is used for many construction purposes, as in
the manufacture of bricks, mortar, plaster, and stucco.
- Among the many other
applications of calcium oxide are its uses in the production of pulp and
paper, in the removal of hair from animal hides, in clarifying cane and
beet sugar, in poultry feeds, and as a drilling fluid.
- Calcium oxide is
also used in dehairing hides, deodorising vegetable oils, in water and
sewage treatment, in flue gas purification, and in the beet sugar
processing industry. Finally, it is used in food for pH-control, and as
a texturising, firming, and anticaking agent
