Yangzi Petrochemical's pre-developed cracking depth control zone in the new area has been applied to the cracking depth control of four 100,000-ton/year cracking furnace on-line chromatographs, and the yield of ethylene has been steadily improved. The depth control of the four new cracking furnaces in the old district is also under intense development. Soon these four cracking furnaces will also use depth control technology to add new means for the company to save energy, reduce consumption, increase production, and increase production.
On-line analysis of pyrolysis furnace exports is a very difficult task in petrochemical production. For many years, there is no mature technology, maintenance is difficult, and the operation effect is poor. For this reason, in 2007, the group company listed this problem as the only instrument technology research project. In order to deeply carry out energy conservation and consumption reduction work, and actively respond to the severe market situation, professionals from Yangzi Petrochemical Olefins Factory and Electrical Apparatus Branch actively carry out on-line chromatographic analysis and operation of pyrolysis furnaces' export products. Through the unremitting efforts of technical research team members, soon The on-line chromatographic technology of the pre-crack gas export has finally achieved gratifying results, and all the eight on-line analysis systems of the cracking furnaces listed as the research projects are operating normally and stable. The main research results include the effective improvement of the instrumentation air system of the chromatograph, the addition of corresponding voltage stabilization and steady flow technologies, and the addition of a vortex refrigeration device, which makes the sample gas components entering the chromatograph more stable, thus making online Chromatographic measurements are more accurate and stable, and the maintenance workload of the entire analysis system is greatly reduced, reducing operational risks.
