Sulfonation of Lubricating Oil Fractions with Sulfur Trioxide

Lubricating Oil Additives

1.1 Lubrication (Rizvi, 2009) The principle of supporting a sliding load on a friction reducing film is known as lubrication (Ludema, 1996). The substance of which the film is composed is a lubricant, and to apply it is to lubricate. These are not new concepts, nor, in their essence, particularly involved ones. Farmers lubricated the axles of their ox carts with animal fat centuries ago. But mo...

Sulfur Trioxide and Oleum

Sulfur trioxide (SO3) and oleums are generally aggressive materials with complicated properties. They are widely used in the process industries. Their main feature is the violent reaction of SO3 and water that occurs in both the liquid and the vapor phase. Oleum (or fuming sulfuric acid) is a solution of sulfur trioxide in 100% sulfuric acid. Its strength is expressed as weight percentage free ...

Sulfur distribution in the oil fractions obtained by thermal cracking of Jordanian El-Lajjun oil Shale

The extracted shale oil by the thermal cracking process of the El-Lujjan oil shale showed that the yield of oil was around 12 wt%. The amount of sulfur in this shale oil was found to increase (from 7 to 9.5 wt%) with the increase of the boiling point for different distillate fractions. Sulfur in Jordanian oil shale was found to be mainly organic sulfur with negligible amounts of inorganic sulfu...

Oil Quality in Diesel Engines With On Line Oil Cleaning Using a Heated Lubricating Oil Recycler

Lubricating Oil Pollution Detection Sensor Design

Metal abrasive particle content in lubricating oil is an important index to judge the degree of deterioration of lubricating oil. Established a spiral electrode capacitance sensor by the finite element software ANSYS, the simulation result shows that the sensor is sensitive to the content of metal abrasive particle in lubricating oil, not affect by the metal abrasive particle itself. According ...
