The model simulated was developed using the bond graph methodology, and MATLAB and 20-sim software were used to obtain the dynamic behavior of the flash. MATLAB was used to determine the input conditions of the separator as they were not provided by the plant information, and 20-sim was used to simulate the bond graph model.
The model of the flash separator was developed using the bond graph methodology . It corresponds to a multi- pseudo bond graph where hydraulic and thermal variables are represented explicitly.
This flash separator is a cylindrical tank of known dimensions to which propane is introduced at known pressure and temperature in thermodynamic equilibrium. The entering propane reaches this equilibrium by means of an expansion caused by a valve placed just before the tank.
MATLAB was used to determine the input conditions of the separator as they were not provided by the plant information, and 20-sim was used to simulate the bond graph model. The simulation results were validated using real operating conditions of the plant.
