The petrochemical industry is facing core challenges such as fluctuations in oil quality, excessive sulfur content, and low fractionation efficiency. Hengmei Electronic Technology provides a comprehensive quality control solution for every stage of petrochemical production, from crude oil entering the factory to finished oil leaving the factory, ensuring that products meet international standards and optimizing production processes.
Core Instruments and Applications
HM-CS1 X-ray fluorescence sulfur analyzer: using the principle of energy dispersion, the detection range is wide from 7ppm to 99%, meeting strict standards such as GB/T17040 and ASTMD4294. The instrument is equipped with a disposable Mylar membrane sample cup to avoid cross contamination, and its rapid analysis ability of 60-600 seconds makes it an ideal tool for controlling the sulfur content of crude oil classification, diesel, gasoline, naphtha and other oil products.
HM-LC fully automatic distillation range analyzer: designed based on the national standard GB/T18255-2000, equipped with a 1920 × 1080 pixel high-definition touch screen and a PT100 temperature sensor from JUMO company in Germany. The steam temperature detection range is 0-400 ℃ (resolution 0.1 ℃), suitable for analyzing the distillation range characteristics of natural gasoline, aviation gasoline, jet fuel, naphtha, kerosene, diesel and other products.
HM-YSZ Acid Value Tester: Combined with program-controlled heating bath technology, it realizes automatic boiling reflux and endpoint judgment, with a measurement error of less than 0.03 mgKOH/g, and can accurately evaluate the acid corrosion during oil refining process.
Specific application scenarios
Rapid evaluation and classification of crude oil: In the crude oil receiving stage of the refinery, the X-ray fluorescence sulfur analyzer (HM-CS1) achieves rapid screening of sulfur content within the range of 7ppm to 99% (60 seconds/sample), combined with an acid value analyzer to evaluate the corrosiveness of crude oil, providing decision-making basis for crude oil mixing and processing schemes.
Optimization of catalytic cracking process: Utilizing a fully automatic distillation range analyzer (HM-LC) to monitor the temperature characteristics of the distillate in real time (with an accuracy of 0.1 ℃), combined with a Karl Fischer moisture analyzer (HM-WS1) to control the product moisture content to ≤ 100ppm, optimizing the operating parameters of the distillation tower, and improving the yield of light oil.
Quality testing of finished oil products: Integrated with X-ray fluorescence sulfur analyzer, acid value analyzer, and flash point analyzer (HM-KS), a factory inspection line for finished oil products is constructed to ensure that key indicators such as sulfur content, acid value, flash point, etc. comply with GB17930 automotive gasoline standards and avoid quality accidents.
Advantages and Value of the Plan
The outstanding advantages of this solution lie in its high precision, fully automated continuous detection, and networked data management capabilities. The repeatability (r) of the X-ray fluorescence sulfur analyzer meets the strict standard of r<0.4347X ⁰·⁶⁴⁴⁶, and the temperature control accuracy of the distillation range analyzer reaches 0.1 ℃, ensuring reliable detection results. The system can complete multi parameter analysis of 20 samples per hour, and the data is automatically uploaded to the MES system to achieve real-time visualization of quality data. Long term application has shown that this scheme can reduce the quality accident rate by 60%, reduce laboratory labor costs by 45%, and significantly improve the economic benefits of refineries.
