Chemical plants consolidating
Of course, efforts to enhance reliability and reduce maintenance costs always involve some degree of change or intervention. The trick is de-risking the situation by avoiding rash decisions and other common mistakes.Below are a few risk mitigation strategies: Be fully aware of machine criticality.How mistakes can be made: Mixing Incompatible Lubricants - This occurs when doing a rolling change-over to a new lubricant that is incompatible with the lubricant previously used and still in the machine.A rolling change-over is periodically adding make-up fluid on top of a previous lubricant of a different type or brand.The mistake is failing to check compatibility and failing to fully drain and flush where required.Machine-Incompatible Lubricants - In certain cases lubricants (additives or base oils) can actually attack machine surfaces and lead to sudden-death failures.Most of these are associated with cutting corners and failing to do proper lubrication engineering.
Wrong viscosity is the most common mismatch of a lubricant to a machine.
Changing a lubricant is an invasive process done by a human being capable of error.
When a completely different lubricant is applied, the risk is magnified due to the unknowns of how the machine might respond (Murphy’s Law stuff).
They have also re-engineered the precision of their lubricant specification.
There are many real and a couple of somewhat imaginary benefits to these consolidation initiatives. These include: The imaginary relates to the false reality that limiting lubricant SKUs to the catalog products of a single major brand can optimize the selection and number of lubricants in typical process industry plants and factories.
