LIME CALCINATION PLANT
[EIRI/EDPR/0807] {J.C: 9421}
INTRODUCTION
Quick lime which is also known as calcium oxide or burnt lime specifically for chemical industries. Quick lime/burnt lime is obtained by calcining pure limestone at high temperature.
Quick lime is used in mortar and plaster in glass production and in metal production industries to remove impurities.
The elements calcium and magnesium that abound so widely in the earth's crust, most commonly occur in carbonate forms of rock, generally classified as lime stone. Chemically it is composed primarily of calcium carbonate, CaCO3, including varying percentage of impurities. Although these carbonates may occur in many other rocks areas and soils in its broadest interpretation a chemical prerequisite for lime stone is that it contains greater than 50% carbonate.
Limestone’s most important chemical characteristic is that when subjected to high temperature, it decomposes chemically into lime, CaO decarbonation occurring through the expulsion of CO2 gas. This primary product, known as quicklime, may be dehydrated or slaked into hydrated lime, calcium hydroxide (Ca(OH)2, the water being chemically complete bined with calcium oxide in an unimolar ratio.
It occurs in varying degrees in nearly every country. It is one of the most bare raw materials employed in industry and construction and has been compared to one leg of a six legged stool around which modern industry revolves, the other legs being coal, oil, iron ore, sulphur and salt.
Lime is one of the oldest chemicals known to man; the process of lime burning is one of the oldest chemical industries. Lime plaster and mortar were used by the Greeks, Romans, Etruscaus, Arabian and Moors. Vitruvious, a Roman Architect under Augustus, wrote the first detailed lime Specifications.
Calcium oxide is also known as lime quicklime, burnt lime, calx, unslaked lime, fluxing lime.
It is a white or gregish white hard lumps, sometimes with a yellowith or burnish tiut due to iron.
Regarding its production, calcium carbonate (lime stone) is roasted in limes until all the carbon dioxide is driven off. The impurities present in calcium carbonate, magnesium, iron and aluminium oxides.
Compared to one leg of a six legged stool around which modern industry revolves, the other legs being coal, oil, iron ore, sulphur and salt.
