John Thompson APC wins new de-dusting contract at PPC’s De Hoek plant
Company News Tuesday, August 11, 2015: JOHN THOMPSON A division of ACTOM (Pty) Ltd
ACTOM Group business unit John Thompson Air Pollution Control was recently awarded a multi-million rand contract by leading cement producer PPC Ltd to replace the original finishing mill 6 electrostatic precipitator (ESP) with a bag filter at its De Hoek factory in the Western Cape.
The reverse-pulse bag filter will reduce dust emissions to the required legislative limits.
The replacement of the ESP with a higher performing dust control system is similar to an upgrade John Thompson APC – then known as ACTOM Air Pollution Control – performed at De Hoek three years ago to enhance the de-dusting system of its kiln 6 and raw mill 6.
As with the earlier upgrade, the new contract has been commissioned to ensure that dust emissions
from finishing mill 6 are maintained at less than 30 mg/Nm3 in accordance with the current environmental regulations. The contract was awarded in November last year for completion in March 2016, with a phased implementation due to cement demand.
The new bag filter, which will have a design air-moving capacity of 41 000 actual m3/h, will incorporate a variable speed drive induced draft (ID) fan and materials handling equipment consisting of a screw conveyor and rotary valve that will discharge the collected dust into an existing product conveyor.
