Secunda
From Wikipedia, the free encyclopedia
Secunda is a fairly new town built around coalfields in Mpumalanga, South Africa.
The town of Secunda was built from scratch when the construction of Sasol Two commenced. Sasol Two (1980) and Sasol Three (1982) produce synthetic fuel, diesel, and related fuels and petrochemicals from coal gasification.
The town has 40,000 inhabitants, with an additional 245,000 people living in the nearby Embhalenhle community. The town has experienced significant growth in the past 5 years due to the expansions underway at the Sasol complex.
The highest structure in Secunda is the 301 metre high chimney at the Sasol Three plant. The chimney is an Eskom type chimney comprising four 301 metre high refractory brick lined concrete flues of 4.6 metre diameter each. The windshield is 292 metres high with an internal diameter of 26 metres. The chimney was constructed by Concor as part of a contract to construct the Sasol Three steamplant with Hochtief. The foundations of the chimney comprised vertical and raked piles. This chimney happens to be the tallest free-standing structure in the Southern Hemisphere.
