Sulphur dioxide removal using South African limestone ...

2010-9-1  South African fly ash and CaO obtained from calcination of limestone in a laboratory kiln at a temperature of 900 °C were used to synthesize CaO/ash sorbent by atmospheric hydration process. The sorbent was prepared under different hydration conditions: CaO/fly ash weight ratio, hydration temperature (55–75 °C) and hydration period (4–10 h).

2009-4-30  1.. IntroductionThe electricity sector plays a pivotal role in the South African economy. South Africa's generating technology is based largely on coal-fired power stations, and at the end of 1999, there were 49 power stations in the country, of which 20 were coal-fired accounting for 90% of the total capacity of 43,142 MW .On combustion, the sulphur contained in the fuel is converted to SO 2.
