Thermodynamic Models ( I ) ÊPregenerated models for 40 systems: yAmine systems yCaustic systems yAcid systems . Whatever process simulator software you are using (Hysys, Aspen Plus, ChemCad, Pro II), the first step is to open a blank worksheet and add a pieces of process equipment: column, condenser, reboiler (as part of the column or separate), pumps and valves and add a streams between them. The mathematical simulation includes (1) a thermodynamic model of the cylinder refrigerant gas based on the principles of conservation of energy and mass, (2) a heat transfer model to predict the transient . These models are also referred to as K models because relative volatility, K i , can be determined by VLE calculations, K i = y i /x i , where y i PVrepresents external free energy. Selection of the appropriate thermodynamic package is one of the first steps when building the mathematical model. Selection of Steady-State Process Simulation Software to Optimize ... Given a process design and an appropriate selection of thermodynamic models, ASPEN uses mathematical models to predict the performance of the process.
