Guangzhou Petrochemical's rapid analysis technology made another breakthrough

"It only takes 5 minutes to detect the octane number of isooctane with near-infrared, and the sample volume is less than 1 ml.
Compared with the traditional method, it not only greatly improves the work efficiency, but also reduces the sample volume
.
" July 19, Huang Xiaoying, director of the production equipment room of Guangzhou Petrochemical Inspection Center, introduced the achievements of Ding Mei's innovation and innovation studio to carry out rapid analysis of technical breakthroughs
.

Since the beginning of this year, Ding Mei Innovation and Effectiveness Studio has earnestly implemented the thematic action requirements, and closely focused on the urgent issues of production and the expectations of employees, and carried out rapid analysis and technical breakthroughs in analysis projects
.
Among them, the near-infrared detection of the octane number of industrial isooctane is one of the technical research topics
.

As an important component of automotive gasoline, industrial isooctane has an average monthly analysis volume of more than 30 batches
.
The traditional analysis method is cumbersome and requires 1000 ml of sample to analyze one data, which takes two hours, and the whole process needs to be guarded by special personnel, which is not conducive to the rapid optimization of production parameters, and also affects the work efficiency of team members
.

"Everyone first scans the spectrum, collects data, and prepares for the establishment of a near-infrared prediction model
.
" As the leader of the studio, Ding Mei took the initiative to provide technical support for the research team
.

After a month of preliminary preparation, at the beginning of July, the research team completed the establishment of the near-infrared model of the octane number of the industrial isooctane sample.
A total of 96 sets of infrared spectra and measured data were collected, 80 sets were used for modeling, and the remaining 16 sets were used for modeling.
Data validation after modeling
.

After dozens of verifications, the new model predicts that the deviation of the octane number of the sample meets the precision control requirements of the standard method.
After the model is put into use, the rapid detection is realized in 5 minutes
.

"Continue to collect data, and strive to build the near-infrared models of other 6 projects such as aromatics, olefins, and benzene content of industrial isooctane, so as to realize multi-purpose and simultaneous detection of one machine
.
" After the detection, the members of the research team immediately discussed the next plan to tap the potential of the near-infrared analyzer
.

The inspection center takes the Model Worker Innovation and Creation Studio as the carrier, and actively mobilizes the backbone of technical skills to participate in the development and application of rapid analysis technology.
Among them, four key research tests, including the application of inductively coupled plasma mass spectrometry in refining metal analysis, and the determination of gasoline composition by rapid chromatography, have been completed.
Breakthroughs have been made and successively put into production and played a role, escorting the safe, green and high-quality development of enterprises with accurate data
