Process simulation is a tricky skill to master.  Even with years of experience, a typical user is constantly facing new problems that they need to address.  There are many issues that can lead to unexpected and unnecessary errors with the use of process simulation tools.  Despite what simulation program you are using, many of these issues are common from one program to another.  In this presentation, we will discuss the “Most Common Pitfalls in Process Simulation“.  For each topic, we will discuss various techniques and methods to fix these troublesome problems and prevent their occurrence.  Topics to be discussed include:
  1. Bad data entry
  2. Simulation defaults
  3. Bad plant data
  4. Thermodynamic method selection
  5. Simulation tolerances and convergence
  6. Recycle identification and handling
  7. Model complexity
  8. Difficult or impossible specifications
  9. Assay pseudo-component development
  10. Assay property blending

This presentation is intended to be broad based and is applicable for both new and experienced users of process simulators.
