Catalytic Cracking Unit Compressor Modeling And Simulation

To meet the need of developing the simulator of the whole flow sheet of the mathematical Plant, mathematical model and simulation software of the plant is developed.In the process of modeling, thermotical character and mechanical character of centrifugal compressor are emphased. Thermotical character is about section parameters and character curves; Mechanical character is about rotor's vibration and axial force. In order to describe thermotical character and mechanical charater of compressor, mechanism model is developed according to the construction and principle of compressor. This model may substitute the usual regress model and logic model, and more roundly describes the running law of centrifugal compressor.The experiment of simulation indicates that the model is in reason, method is right, and the model can describe the centrifugal compressor. Consequently, it has reference value to operators and designers.
