The project of Development and Industrial Application of Sinopec’s New-Generation Green and Intelligent Integrated Aromatics Technology, jointly researched and developed by Engineering Construction Corporation, Research Institute of Petroleum Processing, Jiujiang Petrochemical and other institutions, has passed the official appraisal of the China Petroleum and Chemical Industry Federation.
This new-generation green and intelligent integrated aromatics technology has developed advanced new-generation p-xylene adsorbents and ethylbenzene-converting xylene isomerization catalysts. It has formed innovative technologies including a novel single-column simulated moving bed adsorption separation process, special internal components, intelligent control systems, inter-column heat integration of distillation towers, steam pressure boosting and process coupling, as well as complete supporting equipment. To date, 25 national invention patents have been granted by the National Intellectual Property Administration.
At present, the technology has been applied to the 890,000-ton-per-year aromatics project of Jiujiang Petrochemical. It has lifted the low-temperature heat utilization efficiency of aromatics by over 50%, reduced the comprehensive energy consumption per unit product by 27%, and the overall technology has achieved an internationally leading status.
