Secunda CTL is a synthetic fuel plant owned by Sasol at Secunda, Mpumalanga 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 and the largest single emitter of greenhouse gas 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.[1] It has total production capacity of 160,000 barrels per day (25,000 m3/d).[2]
