Lubricating Oil - an overview | ScienceDirect Topics

This article focuses on petroleum-based lubricating oils. Lubricating oils are composed of 80–90% petroleum hydrocarbon distillate with 10–20% additives to impart specific properties to the oil. The petroleum hydrocarbon distillate generally consists of paraffinic or naphthenic compounds, whose properties are listed in Table 1. Table 1.

The Re-refining of Used Lubricating Oils

The oil is boiled in a closed container to remove the water that has been mixed into it. Step 2 - Diesel stripping The dehydrated oil is then fed continuously into a vacuum distillation plant for fractionation. Lighter oils boil off first a nd are removed, followed by the lubricating oil itself.

Lubricant Additives - A Practical Guide

Lubricant Additives - A Practical Guide. Noria Corporation. Lubrication professionals often become very familiar with the base oil viscosity of their lubricants. After all, viscosity is the most important property of a base oil. Baselines for incoming oils are set and the health of the lubricant is monitored based on viscosity alone.
