Secunda CTL is a synthetic fuel plant owned by Sasol at Secunda in South Africa. It uses coal liquefaction to produce petroleum-like synthetic crude oil from coal. The process used by Sasol is based on the Fischer–Tropsch process. It is the largest coal liquefaction plant in the world.
Secunda CTL consists of two production units. The Sasol II unit was constructed in 1980 and the Sasol III unit in 1984. It has total production capacity of 160,000 barrels per day (25,000 m3/d).
The Sasol III Steam Plant has a 301 m (988 ft) tall chimney which consists of a 292 m (958 ft) high windshield and four reinforced concrete flues which make it one the tallest structures in Africa.
As a major component of South Africa's economy, Secunda was in turn a major target of the African National Congress during the apartheid era. Two ANC attacks (and their aftermath) were dramatized in the 2006 film Catch a Fire.
