Subtitle: Determining Loss of Oil Properties
When oil has been in storage for a long time, it is important to assess the condition of the oil to see if it has lost its properties. The oil's properties can be evaluated by examining the physical and chemical characteristics of the oil, including viscosity, flash point, acid number, and sulfur content.
Viscosity is a measure of the oil's ability to resist flow. When the viscosity of the oil is measured, it should be compared to the expected viscosity for the oil. If the viscosity is lower than expected, it may be an indication that the oil has lost some of its properties.
Flash Point is the temperature at which the oil produces a flash of light when exposed to a flame. If the flash point of the oil is lower than expected, it could indicate that the oil has degraded.
Acid Number is an indication of the amount of acid present in the oil. If the acid number is higher than expected, it could mean that the oil has become acidic due to oxidation.
Sulfur Content is a measure of the amount of sulfur present in the oil. If the sulfur content is higher than expected, it could indicate that the oil has been contaminated with sulfur compounds.
By examining the physical and chemical characteristics of the oil, it is possible to determine if the oil has lost its properties. If any of the characteristics are outside of the expected range, it could indicate that the oil has been damaged or contaminated. It is important to regularly inspect stored oil to ensure it is in good condition.
