Lanzhou Petrochemical online spectrum detection technology applied successfully

On September 9th, the “online spectrum analyzer prototype” developed by Lanzhou Petrochemical Research Institute was successfully applied in the styrene-butadiene plant of the rubber plant. This technology fills the domestic gap and is an innovative technology with independent intellectual property rights. Online spectral detection technology replaces traditional manual detection technology and is faster, more accurate, and easier to operate.

Based on the actual needs of production equipment and the research results in the field of spectroscopy, Lanzhou Petrochemical Research Institute applied spectrum technology to the field of online testing for the first time. Since the styrene-butadiene rubber production device adopts the manual sampling analysis method, the oxygen content of the recovered butadiene material is analyzed every 4 hours, the operating pressure of the device is micro-negative pressure, and the infiltrated air cannot be found in time, and the device urgently needs a continuous fast online. Analytical apparatus and means for detecting oxygen content in butadiene.

The online spectrum analyzer is used to detect the oxygen content of butadiene in the styrene-butadiene plant of the rubber plant, and can directly detect the oxygen content and data curve of the raw materials online. At the site of the device, the researchers used the national standard method and the online spectrum analyzer to measure the accuracy and repeated tracking and comparison. The results of the two measurements are completely consistent. The online spectrum analyzer is superior to the manual measurement in terms of fast, accurate and easy operation.

It is reported that the safety of laser radiation of the online spectrum analyzer has passed the evaluation of the “National Explosion-proof Electrical Product Quality Supervision and Monitoring Center”, and the safety meets the site requirements. The successful development of online spectral detection technology will provide reliable safety monitoring methods for chemical industry production, which is of great significance for reducing safety risks and improving the control capabilities of production equipment.
