Introduction
GB/T 34100—2017 Standard Interpretation
Foreword: In the process of petroleum refining, even trace amounts of sulfides in the raw materials can cause poisoning of certain processing catalysts. This standard is applicable to the determination of sulfur content in processing raw materials and products, and can also be used for the determination of sulfur content in the control analysis of intermediate products.
1. Scope
| Scope of application | Sulfur content determination range | Sample type |
|---|---|---|
| Light hydrocarbons, motor fuels and other oils (such as gasoline, diesel, biodiesel, etc.) | 1.0 mg/kg to 8000 mg/kg | Naphtha, distillate oil, ethanol, fatty acid methyl ester (FAME), jet fuel |
Instrument and working principle
The combustion furnace temperature is controlled at 1075°C ±25°C to ensure complete oxidation of the sample. The combustion tube is made of quartz and supports both syringe direct injection and boat injection. At high temperatures, sulfur is oxidized to sulfur dioxide (SO₂), which is then irradiated with ultraviolet light to excite a fluorescent signal.
Method Overview
The sample burns at high temperature and in oxygen-rich conditions to generate sulfur dioxide. After the moisture is removed by the drying tube, the sulfur dioxide enters the detector, and its fluorescence intensity is proportional to the sulfur content.
Instrument Preparation and Calibration
| Instrument Equipment | Key Parameters | Calibration Requirements |
|---|---|---|
| Combustion Furnace | 1075°C ±25°C | Check system performance using standard solutions every day |
| Flow Controller | Oxygen Flow Rate: 450~500 mL/min | Establish a linear calibration curve (R² ≥ 0.999) |
Implementation Suggestions
1. Use standard substances for regular calibration to ensure detection accuracy. 2. Pay attention to the uniformity and volatility of the sample and choose an appropriate injection method. 3. For samples with high sulfur content, use volume dilution to avoid overloading.
Precision Requirements
| Sulfur Content (mg/kg) | Repeatability r | Reproducibility R |
|---|---|---|
| <5 | 0.2 | 0.6 |
| 5~100 | 0.6 | 1.9 |
| >100 | 3.4 | 10.9 |
Result Calculation and Reporting
Sulfur content (X) is calculated according to the formula, and the reported value is retained to 0.1 mg/kg or 1 mg/kg according to the test results. Quality assurance and control requires daily analysis of QC samples.
