The 865-km cross border pipeline from the Temane gasfield to Sasol's synfuels plant at Secunda, near Johannesburg began operations in February, 2004, when the first gas arrived at Secunda on 21st of the month. The capacity-expansion project primarily involves the installation of a new compressor station, including two new gas-turbine-driven compressor units and ancillary equipment to increase the pipeline gas flow rate, at Komatipoort in South Africa. The existing pressure protection system at Secunda will also be upgraded to accommodate the increased gas flows.
