| Group Five Engineering and Construction Services (E&CS) was
awarded this engineer, procure and construct (EPC) contract
for Exxaro TSA Sands in December 2011. The contract involves
harnessing furnace off-gas to generate electrical power using
gas engines. Total plant electrical output will be 15 MW. The
contract started in June 2012, with the expected completion
date in June 2013.
All construction work has to be undertaken whilst the existing
plant is in production, with the resultant safety requirements
of a working site in place.
The contract involves collecting the furnace-generated off-gas,
which is presently being flared into the atmosphere and using
this fuel source to run gas engines capable of generating
electrical power. The off-gas will be collected, mixed, scrubbed,
cleaned and the moisture removed before being used in the
gas engines. The group has been responsible for the detailed
engineering and design for the gas handling and the complete
power plant.
The technology to be used draws on the group’s long term
relationship with global power group General Electric, in
particular their range of “Jenbacher” industrial gas-powered
generators.
During 2011, the group constructed a similar plant for Exxaro
at their Beatrix Mine.
The contract is a good fit with the group’s sector
focus on power and demonstrates the group’s
ability, particularly the EPC packaging of small
to medium power plants using industrial waste,
gas and liquid fuels. |
