The point of origin is usually a mixing valve (the oil mist generator), connected to this header.
Branch lines often feed oil mist to hundreds of rolling elements in the many pumps and drivers connected to a plant-wide system.
As of April 2019, over 160,000 process centrifugal pumps are operating with oil mist as the sole bearing lubricant.
The estimated number of electric motors on pure oil mist exceeds 50,000; several of these at a Texas Gulf Coast petrochemical facility have been in flawless service since 1978.
These analyses are highlighted in Bloch/Geitner/Ehlert "Optimized Equipment Lubrication, Oil Mist Technology, and Storage Preservation," (late 2019), Reliabilityweb Publishing, Ft. Myers, Florida.
