Process Simulation PET555

Process Simulation means to predict the output streams from an industrial processing facility, when it's input streams, energy exchange and layout are known. This course addresses the theory and implementation of the calculation methods involved, as well as the use of commercial process simulation software.

Learning outcome
Upon completion of this course, the student should be able to:
  1. Combine the mathematical expressions that relate the principles of thermodynamics with material models (e.g. equations of state), to produce the sets of equations that link properties of process fluids to their chemical compositions.
  2. Apply the numerical methods, construct algorithms, and implement the computer codes required to solve these sets of equations.
  3. Prepare various technical information to go as input values to process simulations.
  4. Build a simple process simulation model using programming tools, such as Matlab or Python.
  5. Build a more advanced process simulation model using commercial software, such as Unisim.
  • Introduction to software
  • Thermodynamic relations, equations of state, mixing rules.
  • Sequential-modular vs. equation oriented solution strategies.
  • Gas compression, flash calculation, phase envelope and phase checking
  • Construction of flow sheets.
