【Learning from Others’ Successes】Jiujiang Petrochemical Develops Its Own Software to Overcome Challenges in Gasoline Analysis

Thread Content

Based on the concept of molecular refining, Jiujiang Petrochemical utilized intelligent technologies to develop accurate and rapid detection methods for gasoline components, and after 3 years of effort, it successfully created a rapid evaluation system for gasoline. This system enables efficient testing by completing 12 key physical property analyses within 22 minutes, significantly improving testing efficiency and quality while reducing the workload on employees and equipment costs. At 8:06 on September 11, Wang Zhihui, a chromatography technician at the testing and analysis laboratory of the Jiujiang Petrochemical Inspection and Metrology Center, tapped the analysis system of the gasoline rapid evaluation software and inserted the newly collected gasoline distillate sample into the automatic chromatography sampler. Subsequently, the injection needle automatically took samples for analysis, and the property analysis spectra appeared instantly, rising and falling like waves. At 8:28, the quick analysis software automatically retrieved the data from the calculation diagram to generate a gasoline property analysis report, which was then uploaded to the system. “This is incredibly convenient – it only takes 22 minutes to complete the analysis of 12 physical properties. ”Wang Zhihui sighed, \"This type of analysis needs to be completed at least 3 times a day; the quick-review software helps us reduce the workload.\" ” Traditional analysis methods suffer from issues such as complex procedures, long processing times, high costs, and large sample consumption. Analyzing just the octane value alone takes over an hour, and there are more than 10 other key properties of gasoline components such as boiling range and density, which require 4 specialized laboratory analysts to use different instruments for analysis simultaneously. Focusing on this pain point, Jiujiang Petrochemical utilized intelligent technologies to develop advanced methods for the precise and rapid detection of gasoline components, and after 3 years of effort, it successfully created a software for rapid evaluation of gasoline quality. Based on the concept of molecular refining, they combined domestically produced high-performance gas chromatographs with intelligently developed algorithms of their own, continuously optimizing both the hardware configuration and software parameters of the instruments. They innovatively adopted a three-instrument testing method, established a rigorous data verification system, and through numerous comparison experiments, developed and validated analysis models specific to over 10 different types of materials, thereby creating an efficient detection approach. The gasoline evaluation software has enabled the inspection and metering center to operate with one person per device. After applying this software, the analysis time is reduced to just 8% of the previous value, the amount of sample used is only 0.1% of the previous level, and the costs associated with labor and equipment are reduced by 80%. First-hand insights □ Gui Yuying, senior engineer at Jiujiang Petrochemical Inspection and Metrology Center: The gasoline rapid evaluation system links analysis data closely with production optimization, providing unprecedented real-time data support for plant adjustments. This enables more precise and agile production control, significantly reduces testing costs, and enhances the scientific basis of production decisions. By integrating intelligent algorithms with detection instruments, this system liberates people from repetitive tasks.
