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.
