• What is flowsheet simulation?- Use of computer program to quantitatively model the characteristic equations of a chemical process
• Uses physical relationships- Mass & energy balance- Equilibrium relationships- Rate correlations (reaction and mass/heat transfer)
• Predicts- Process stream data (flowrate, composition, properties…)- Operating conditions (pressure, temperature, geometry…)
• Advantages- Plant design time- Improve current process / predict new process- Assist plant operation
• All steps needed to fully define the physical properties before the simulation- component selection and characterization- property methods and databases- property estimation / structure drawing- property analysis / data regression
