What is “Process Simulation”?
Q: What does the word “simulate” mean?
Building a process model Predicting how a process would actually behave Performing an experiment (on computer)
Incentives: Highly cost effective Reasonably accurate Proactive approach

Sequential modular approach Individual equipment blocks may require
iterative solution algorithms
Overall process solution is sequential & not iterative
(Turton et al., 1998)
