Introduction

This specification is based on JJF 1001-2011 "General Terms and Definitions of Measurement", JJF 1059.1-2012 The determination and representation of certainty, JJF 1071-2010 "Rules for the preparation of national metrological calibration specifications" was compiled. Editing In the process, reference is made to SH/T 0689-2000 "Total sulfur content of light hydrocarbons and engine fuels and other oils. Determination of Methods (UV Fluorescence) and ASTM D5453-2016 "Ultraviolet Fluorescence Method for the Determination of Light Hydrocarbons, Spark Ignition Test Method for Total Sulfur Content in Engine Fuels, Diesel Engine Fuels and Engine Oils (StandardTest) MethodforDeterminationofTotalSulfurinLightHydrocarbons,SparkIgnitionEngine Fuel, DieselEngineFuel, andEngineOilbyUltravioletFluorescence) and other documents Technical requirements and test methods.

SH/T 0689-2000 Determination of total sulfur content of light hydrocarbons, motor fuels and other oils Light method) ASTMD5453-2016 Determination of light hydrocarbons, spark-ignition engine fuels, diesel fuel by UV fluorescence Test Method for Total Sulfur Content in Engine Fuels and Engine Oils (StandardTestMethodforDeterminationof TotalSulfurinLightHydrocarbons, SparkIgnitionEngineFuel, DieselEngineFuel, andEngineOilbyUltravioletFluorescence) For dated references, only the dated version applies to this specification; any undated quotation The latest version (including all amendments) applies to this specification.

3 Overview

The instrument is widely used to determine the total sulfur content of petrochemical products such as refined oil, crude oil, distillate oil and petroleum gas. The measuring principle is as follows. the hydrocarbon sample is directly injected into the cracking tube or the injector, and the sample is sent to the high temperature combustion by the injector. tube. Under oxygen-rich conditions, the sulfur in the sample is oxidized to form sulfur dioxide gas, which is converted into ultraviolet light by water. It is excited state. Fluorescence is emitted when sulfur dioxide is returned from the excited state to the ground state, and is detected by a photomultiplier tube. Sulfur content. The instrument consists of a sample introduction unit, a pyrolysis unit, a drying unit, an ultraviolet light source, a reaction chamber, and a detection unit. And the display unit composition, as shown in Figure 1. Figure 1 Structure diagram of the ultraviolet fluorescence analyzer

4 Measurement characteristics

The metering performance of the instrument is shown in Table 1.
