How Millar Western’s pulp operations employed a mobile oil-cleaning unit to enable online filtration
An issue with continuously dirty filters recently led to detailed investigation of an online filtration system at Millar Western’s pulp mill in Whitecourt, Alberta.
Aaron Chambers, CLS, the condition-based monitoring (CBM) coordinator at the Whitecourt mill, says that in September 2018, his team discovered the slab press’s hydraulic system had electrostatic discharge occurring as it filtered oil through a machine-mounted kidney loop.
The cost to replace the oil altogether would have been approximately $28,000.
