Environmental pollution has attracted close attention from governments and the public around the world, and the demand for protecting the ecological and atmospheric environment is increasing day by day. Humans cannot do without 5 minutes of air, 95% of which is distributed within a thickness of 12km on the Earth's surface. The main culprit causing atmospheric damage and pollution is CO₂And SO₂Emissions. CO₂And SO₂The lower the sulfur content of gasoline, diesel, heavy oil, and other fuels used in vehicles, ships, and aircraft, the greater the reduction in atmospheric pollution caused by the combustion of power fuels. Both Europe and China have established a series of sulfur-containing standards to restrict production and emissions. SO₂It can also cause catalyst poisoning in the petrochemical industry and pose hazards such as acid rain in the atmosphere.
The X-ray fluorescence sulfur analyzer is a specialized X-ray fluorescence analyzer developed and manufactured to meet the needs of detecting sulfur content in oil products. It adopts the principle of energy dispersion and is designed with an integrated electromechanical microcomputer for fast and accurate analysis. Its repeatability and reproducibility meet the relevant requirements of national standard GB/T17040 and petrochemical industry standard SH/T0742, and also fully comply with the stricter requirements of American national standard ASTMD4294-03. It provides an important means for detecting sulfur content in crude oil or petrochemical production processes. The instrument itself is green and environmentally friendly, and its price is only a fraction of imported instruments
1.2 Main purpose
1. Measure the total sulfur mass percentage content of crude oil, petroleum, heavy oil, diesel, kerosene, gasoline, and naphtha;
2. Measure the total sulfur content in coal chemical products, such as primary benzene;
3. Measurement of total sulfur or sulfide content in other liquid samples;
4. In fine powder samples, such as petroleum coke modified asphalt, carbon, total sulfur, or SO₃Determination of content.
