Getting to Know Demulsibility

By Dustin Flynn on Thu, Mar. 25, 2021

Demulsibility

What is Demulsibility?

Demulsibility is the ability of oil to separate from water. Oil and water naturally separate because like molecules attract each other. Oil sticks with oil, water sticks with water. Oil is "hydrophobic", or "afraid of water," which is a benefit when it comes to fluids like turbine oil.

An Aluminum Refinery Faces Premature Gearbox Oil Changes

By Jim Harlan on Wed, Dec. 14, 2016

The Application

An Australian aluminum refinery was consistently performing premature gearbox lube oil changes on seven base drive units due to oil and particulate contamination.

With an average operating ISO code of 20/18/16 and average water levels of 4742ppm, the 360 liters / 90 gallons of ISO VG320 gear oil was being changed far too often. Cost per gearbox oil change (excluding crane, lost production, labor) is $17,962.60 which adds up to $125,738.20 for all seven units.
