China's first improved heavy diesel 95% point online analyzer developed successfully

This instrument was independently developed and designed by Lanzhou Petrochemical Automation Research Institute and is a key project in the scientific research and technology development of Lanzhou Petrochemical. It has been three years since the project was established in 2015. Through the phased research work of analysis mechanism research, mechanism prototype design and molding prototype construction, the project has made technological breakthroughs in analysis methods, analysis systems, control systems and peripheral systems.

"The main improvement point of this instrument is the improvement of analytical methods, the sample consumption is reduced by 33%, the power consumption is reduced by 57%, and the flushing process is added, which effectively alleviates the internal coking of the instrument and prolongs the service life of the instrument. The all-metal hollow design replaces the original glass metal structure, improves the performance of the analyzer and reduces the assembly technical requirements. The third is the improvement of the electric heating rod, which replaces the DC metal straight tube with the AC ultra-fine spiral heating coil, completely eliminating the original DC. The failure of the power supply.” On the morning of August 28th, Zhao Li, technical director of the 95% point online analyzer project group of Lanzhou Petrochemical Automation Institute. Through the implementation of a series of improvement measures, the vacuum core effect, energy saving effect, core component life and other instrument core indicators of the improved heavy diesel 95% point online analyzer increased by more than 50%.

The improved heavy diesel 95% point online analyzer project has been applied for from the pre-research to the results, and has applied for 16 national patents and 9 national patents. The research results in December 2017 were officially put into use in the Changsan Petrochemical 5 million tons atmospheric and vacuum distillation unit. The real-time analysis data of the instrument has become an important basis for equipment process optimization and quality control. The estimated annual economic benefit is about 2 million yuan. . The research results of this project are advanced in technology, the analysis data is real and effective, and the core performance is improved significantly. The future project team will combine the on-site requirements of the equipment to promote the project research results and improve the overall operation level of the online analytical instruments of Lanzhou Petrochemical Company.
