DETERMINATION OF TOTAL BASE NUMBER IN MARINE ENGINE LUBRICANTS BY ELEMENTS

The present invention provides a method for determining the TBN of a used lubricating oil by measuring with a single device at least one element, such as sulfur, and correlating the measured amount to the oil's TBN. Preferably, a spectroscopic device is used to make the measurement. L'inve...

Zusammenfassung:	The present invention provides a method for determining the TBN of a used lubricating oil by measuring with a single device at least one element, such as sulfur, and correlating the measured amount to the oil's TBN. Preferably, a spectroscopic device is used to make the measurement. L'invention concerne un procédé permettant de déterminer l'indice de base total d'une huile lubrifiante utilisée, qui consiste à mesurer, à l'aide d'un unique dispositif, au moins un élément, tel que du soufre, et à mettre la quantité mesurée en corrélation avec l'indice de base total de l'huile. L'on utilise de préférence un dispositif spectroscopique pour effectuer ladite mesure.
