Oil Viscosity Index Standardised Using In-line Viscometer

A worldwide maker of premium base oil for lubricants, based in the western U.S., has standardised on Cambridge Viscosity (USA) process viscometers for all viscosity index (VI) refinery applications. VI indicates how the oil viscosity changes with temperature, and is a critically important parameter in lubrication oil. Incorporating VI measurement directly in their process lines allows this refiner real-time control in making lubricating oils.

“We tested the Cambridge viscometers extensively and selected them for their accuracy, reliability and ease of installation and use,” says the chief engineer for the oil refinery company. “We use two viscometers in each line to measure the lube oil at 40oC and 100oC, so that we know the VI real-time throughout the process.”

“Accurate, real-time viscosity measurement enables this refiner to monitor and control the viscosity index of their premium base oils throughout manufacture, which improves product quality and refinery throughput,” says Cambridge Viscosity CEO Robert Kasameyer. “In addition to being precise and dependable, Cambridge viscometers are small for ease of installation directly in-line or in bypass conditioning systems. The viscometer’s self-cleaning design enables the refiner to operate without costly maintenance and re-calibration.”
