Method and device for constructing oil refining whole-process simulation model at molecular level

The invention relates to a method and device for constructing a molecular-level oil refining whole-process simulation model, and the method comprises the steps: adding constructed single-device molecular level models corresponding to various production devices into a single-device molecular level model library; when an oil refining whole-process simulation model is constructed subsequently according to different oil refining production lines or different processes, reuse of the existing single-device molecular level model can be realized, zero construction of all production devices is not needed, adaptive combination and arrangement of the single-device molecular level model can be flexibly performed according to different modeling requirements, and the modeling efficiency is improved. The building efficiency of oil refining full-process simulation models corresponding to different oil refining production lines or processes can be improved; meanwhile, the model parameters corresponding to the molecular level
