Process twinning Research Center compares ASPEN PLUS and other foreign process twinning industry software products, develops physical property databases of different kinds of substances in process industry material transformation and general and special unit operation models based on accurate physical property databases. It provides integrated computing requirements for process physical property analysis, data integration, parameter regression, energy exchange, reaction simulation and separation simulation under industrial network environment for the construction of process twin system, and supports the digital twin of oil refining, ethylene, aromatics, steel, cement and other industrial processes.
