The system collects data from LIMS and PHD then builds models with a block that transfers lump of molecular structure to lump of NBP to realize total process simulation. The quality indexes of products are predicted by intelligent algorithm. User is guided with friendly GUI to make optimization schemes by simple operation. The system ensures the accuracy of simulation while packaging the complex process of data collecting and data processing, simplifying the operation of model with GUI. This process simulation and optimization system is successfully applied in a case study of hydro-cracking unit,which validates the convenience and effectiveness of its operation.
