神华包头特大煤制烯烃项目通过最后评估

项目在“五一”前夕通过国家正式核准之前的最后一次评估。评估工作由国家发改委委托中石化经济技术研究院组织实施，随着此次评估的顺利进行，中国首套煤制烯烃工程开工将为期不远。此项目的实施，以煤代油发展煤制烯烃产业，对我国煤化工产业科学及可持续发展具有重要示范作用。

Development and Application of Heat-integrated Aromatics Fractionation Process

The PRO/Ⅱ process simulation software was applied to carry out simulated calculation of the aromatics fractionation unit and the heat integrated rectification process was proposed for the aromatics fractionation section of the 1.0 Mt/a toluene disproportionation unit at the Zhenhai Refining and Chemical Company. The optimized operating parameters were obtained through the energy utilization analysis,process simulation,heat exchanger calculations and comparisons of utility consumption. The operation of commercialized unit has revealed that the design parameters of each rectification column were consistent with the operation results,and the utility consumption was about 47% lower than the traditional heat integrated process.
