Total Sulfur Analysis in Base Oil Samples Using TS 7000 According to ASTM D7183

Oil refinery and clouds in sky.

Base oils having applications to manufacture products including lubricating greases, motor oil and metal processing fluids and is produced by means of refining crude oil. During the refining process, light and heavy hydrocarbons are separated – the light ones can be refined to make petrol and other fuels, while the heavier ones are suitable for bitumen and base oils. 

By using hydrogenation technology in this process, in which sulfur and aromatics are removed using hydrogen under high pressure, extremely pure base oils can be obtained, which are suitable when quality requirements are particularly stringent. The sulfur content in these high-quality base oils will be very low ppm or ppb level. This application note describes the principle of operation and performance of the TSHR 7000 Total Sulfur Analyzer for the determination of Trace Level Total Sulfur analysis in these type of base oil samples according to ASTM D7183 methodology.
