英文摘要: Molecule management for petroleum refining industry is an opportunity for efficient conversion at molecular level from crude oil to high value-added products, and also can solve the problem caused by the resource degradation under stricter environmental regulations. Implementing molecule management for refining, as one of the modern development directions in the petroleum industry, is complex system engineering. In this project several fundamental theories for molecule management in the refining process will be studied. First, a characterization method for predicting equivalent molecular composition of any petroleum fraction will be proposed based on available analytical information. Then the transformation rules of petroleum fractions will be revealed by developing free-radical kinetic reaction networks. As an integrated example, the molecular level simulation for the hydrocracking process will be performed based on the detailed composition characterization analysis. Further, an innovative and critical separation technology in refining process will be analyzed and developed, and the separation sequence by superstructure modeling will be optimized. Finally, the optimization model of the molecule management of multiple operating units in the refinery will be built. This model is a multi-layered structure system and will be solved by developing a new decomposition-coordination algorithm. The outputs of this proposal will build a solid theoretical foundation for the on-demand, on-time production planning optimization of modernized refineries in China.
