Sasol to build R1,1bn gas compression station

By Olivia Spadavecchia, Engineering News, 05/02/2008

Sasol, iGas and Compania Mozambicana de Gasuduto, as joint partners in the Republic of Mozambique Pipeline Investment Company (Rompco), on Tuesday announced the construction of a R1,1-billion gas compression station, in Komatipoort.

The station would facilitate a 20% expansion of natural gas delivery from Mozambique to South Africa by the end of 2009, increasing gas delivery capacity from the current 120-million gigajoules a year to about 147-million gigajoules a year.

Sasol, which has a 50% shareholding in Rompco, said that construction would start by mid-2008, and that the engineering, procurement and construction management contract had been awarded to Foster Wheeler South Africa.

It explained that two gas-turbine-driven compressor units, and ancillary equipment, would be used at Komatipoort to increase gas flow rates in Rompco's 865-km-long transborder pipeline that transports the natural gas from the Pande and Temane gasfield in Mozambique to Sasol's operations at Secunda and Sasolburg, in South Africa.

The additional gas would be used as part of the first phase of a planned 20% expansion of Sasol Synfuel's capacity at Secunda over the next eight years.

Three-quarters of the eventual additional Synfuels capacity would use natural gas as feedstock with its more benign effects on the environment and the balance would be based on fine coal reserves.

Some of the first phase additional gas is earmarked for the gas-turbine-driven electricity generators recently ordered by Sasol Synfuels in Secunda. Commissioning of both the pipeline compressor station as well as the gas turbines is expected by late 2009.

The pipeline forms part of the $1,2-billion Natural Gas venture, inaugurated by former Mozambican President Joachim Chissano and President Thabo Mbeki on June 1, 2004. It is designed to have the capacity to transport 240-million gigajoules of gas a year.

The project is expected to provide short-term employment for about 450 people of whom about 150 will be skilled artisans and 300 local workers.

The Rompco shareholding partners are the South African government through iGas with a 25% stake, the Mozambican government though Companhia de Mocambicana de Gasuduto with 25%, and Sasol Gas with a 50% shareholding.
