Introduction

In the process of petroleum refining, even some of the raw materials contain traces of sulfide can cause some processing catalyst poisoning. This standard applies In determining the processing of raw materials and products in the sulfur content can also be used for intermediate product analysis of sulfur content determination. Light hydrocarbons and motor fuels and other oils Determination of total sulfur content - UV fluorescence method Warning --- personnel using this standard should have formal laboratory work experience. The use of this standard may involve some danger Materials, equipment and operations, this standard does not indicate all possible safety issues. It is the user's responsibility to take appropriate safety and health measures Shi, and ensure compliance with the conditions of the relevant state laws and regulations.

1 Scope

This standard specifies the method of determination of total sulfur content of light hydrocarbons and engine fuels and other oils by UV fluorescence spectrometry. This standard applies to the determination of the boiling range between 25 ℃ ~ 400 ℃, the kinematic viscosity at room temperature 0.2mm2/s ~ 20mm2/s Total liquid sulfur in liquid hydrocarbons, including naphtha, distillate, engine oil, ethanol, fatty acid methyl esters (FAME), and motor fuels such as steam Oil, Oxygenated Gasoline (Ethanol Blends, E-85, M-85), Diesel, Biodiesel, Biodiesel Blending and Jet Fuel. Total sulfur content measurement The range of 1.0mg/kg ~ 8000mg/kg. This standard applies to the determination of halogen content of not more than 100mg/kg total sulfur content of liquid hydrocarbons. Note. If the sulfur content is low and the nitrogen content is high, the nitrogen content has an influence on the sulfur content determination result.

3 Method summary

The syringe can be used to inject the sample directly into the high temperature combustion tube; it is also possible to inject the sample into the sample boat and push the boat to high temperature Burning tube. Under high temperature, oxygen-rich conditions, sulfur in the sample is oxidized to form sulfur dioxide (SO2). The gas generated after the combustion of the sample passes first Removal of water from the device in the gas water, and then by ultraviolet (UV) light irradiation, sulfur dioxide (SO2) to absorb the energy of ultraviolet light into excited state Of sulfur dioxide (SO2 *). Sulfur dioxide (SO2) from the excited state returned to the ground state when the fluorescence emitted by the photomultiplier tube detection by The resulting signal value calculates the sulfur content of the sample. Warning --- Exposed to excessive amounts of UV light harmful to health. Operators should avoid exposure of any part of the body to UV light and secondary or Scattered by the radiation of light, especially the eyes. ......
