PROJECTS & CONTRACTS
Illovo Sugar appointed Bosch Projects as engineering, procurement
and construction management (EPCM) consultants for its subsidiary
Zambia Sugar’s Nakambala expansion project.
This contract, which involved the expansion of the raw house
production capacity and the installation of a new sugar refinery,
sugar conditioning plant and packing plant, was commissioned in
May 2016, on time and within budget.
“Scope of the project for Bosch Projects encompassed the design
and construction of a modern, high specification refinery, required
to more than double the factory’s annual refined sugar production
capacity, to 90 000 tons,” says Steve Rosettenstein, director: sugar,
Bosch Projects, part of the Bosch Holdings group of multidisciplinary
engineering companies. “As a result of the factory upgrade and
implementation of the latest processing technologies, annual sugar
production capacity at Nakambala is expected to increase from
420 000 to 450 000 tons.”
Bosch Projects was also awarded the contract to design
and supply sugar processing equipment for the project, which
was manufactured to pristine quality standards in Durban and
transported by road to Zambia.
State of the art processing equipment was designed in-house by
the Bosch Projects team for high productivity, cost efficiency and
extended service life at Nakambala.
This equipment includes a continuous vacuum pan (CVP), clear
juice heaters, a vacuum seed receiver, condensate flash vessels,
condensers and a press water clarifier. A refinery evaporator, a
50 m high refined sugar conditioning silo and a lime and liquor
wheel were also supplied.
During construction of the PAAR project, over 1 200 tons of
structural steel was erected, 1,6 km of piles were installed and
3 400 m³ of concrete was poured.
Expansion of the Nakambala sugar mill and refinery has
consolidated Zambia Sugar’s position as Africa’s single largest cane
sugar producer and forms part of Illovo Sugar’s strategy to focus on
growth within its domestic and regional markets.
This project has also boosted the development of small holder
cane farmers in the area and provides employment opportunities for
the local community.
Bosch Projects received a CESA commendation award for the
Nakambala Product Alignment and Refinery project, in the category
of ‘Best International Project’. The annual CESA Excellence Awards
event gives recognition for engineering excellence.
Apart from sugar and ethanol engineering, Bosch Projects also
offers solutions in water and waste water, energy and industrial
plants, roads, land and building developments, as well as ports
and terminals.
