Largest electrostatic precipitator
to date commissioned at Impala
The largest BATEMAN-ELEX electrostatic precipitator
installed to date by BATEMAN has been commissioned at Impala Platinum
Limited Mineral Processes’ Phokeng site near Rustenburg. With a
structural height of over 30 m, the precipitator is the fifteenth such
project to be completed by BATEMAN for Impala.
In terms of a contract for
the supply of a hot-gas cleaning system to recover the product emissions
from a spray-concentrate drier at Impala, BATEMAN designed, fabricated,
supplied, installed and commissioned the precipitator, as well as two
induced-draft fans, a glass-reinforced-plastic stack and the interconnecting
ducting.
“The precipitator recovers the product
from dust-laden gas from a 50 t/h drier and has outlet emission levels
of less than the guaranteed design parameter of 30 mg/Nm³,”
reports BATEMAN Project Engineer, Woitek Liberda. “To achieve this,
we designed a three-field electrostatic precipitator based on the latest
ELEX technology. Such high collection efficiencies can only be achieved
with the use of equipment that allows close physical tolerances between
the discharge and collecting electrodes. In addition, the equipment
was designed specifically to operate at the higher temperatures encountered
in a smelting operation such as at Impala, without any distortion of
the electrodes occurring.”
BATEMAN has supplied all of Impala’s precipitators.
It was awarded this latest project in late November 2001 and completed
it in one month less than the 12-month period projected for the supply
of a precipitator of this size.
BATEMAN-ELEX electrostatic precipitators can operate
at temperatures of up to 450°C, can handle wet and dry dusts equally
effectively and offer low energy consumption and spares cost. The largest
BATEMAN-ELEX electrostatic precipitator installed to date by BATEMAN
has been commissioned at Impala Platinum Limited Mineral Processes’
Phokeng site near Rustenburg. With a structural height of over 30 m,
the precipitator is the fifteenth such project to be completed by BATEMAN
for Impala.
