The Paraho Development Corporation developed new vertical shaft kiln hardware and process techniques and confirmed new technology in the 1960s by building three large commercial lime kilns. In the 1970s the company adapted their lime kiln technology to oil shale retorting.
Lime is manufacture in various types of kiln by one of the following reactions; CaCO3 + heat CO2 + CaO ( high calcium lime) CaCO3.MgCO3 + heat 2CO2 + CaO.MgO ( dolomite) The heart of a lime plant is the kiln. There are various types of kiln. The two main types that are commonly employed are the vertical shaft and rotary kilns.

On vertical kilns, the limestone moves downward and the hot gases flow upward through the limestone. These kilns usually use limestone sizes between 0.13 to 0.2m and operating temperature is between 900 to 1000°C. Vertical kilns are fuel efficient but limited in capacity. On horizontal kilns, the kiln …

The next most common type of kiln in the United States is the vertical, or shaft, kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary
3) Lime Calcining (Conversion of limestone (CaCo3) to lime (CaO)) Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required.
