General description and relevant information

Attention:

  • Changes in the course schedule agreed with Advanced Separation Processes (Fridays, 15:00 to 19:00).

The aim of the course is to optimize processes and products using advanced mathematical programming tools and process simulation.

Continuous product and process design using process simulation:

  • General overview of process simulation: (Dis)advantages, commercial tools, basic steps.
  •  Distillation in Aspen Plus: Very basic overview, files, reactors + example.
  • Case studies: cyclohexane production, PFR reactor, ammonia, IPA dehydration, 3 component separation using hot/cold utilities, solvent ratio in extractive distillation.
Distillation in product and process design using process simulation:
  • Distillation basics: column sizing & rating fundamentals, operating window & problems.
  • Distillation in Aspen Plus: shortcut & rigorous, DSTWU + examples + tutorial, Radfrac & design specs.
  • Case studies: radfrac tutorial, MeOH+water column internals, MCV production.
Overview of the estimation of physical properties capabilities in Aspen Plus (molecular design):
  • What is property estimation?: Pure component, T-Dependant, binary parameters.
  • Molecular structure: atoms & bonds, PCES of i-BuOH and C12H9ClO, PCES of H2O+DMA & decanter.
  • Estimation with limited data: experimental data, PCES of PV for 2-BuOH.
Physical properties capabilities in Aspen Plus® (molecular design):
  • Physical properties estimation: properties = feasible = €, EOS vs gamma, Henry’s Law .
  • Expert system: property methods, expert system, examples.
  • Examples: data regression, 2 thermo models in a flowsheet, table generation system (TGS).
Decision making under uncertainty in product and process design: decision trees:
  • Basics of probabilities: coin flipping, expected value, roulette & WWTBAM.
  • Expected value in decision making: decision trees, toy example, probability distribution.
  • Posterior probabilities: EVSI, toy example, example (build a plant?).
Environmental aspects in product and process design: life-cycle assessment:
  • Fundamentals of life-cycle assessment: sustainability concepts and why LCA is needed.
  • LCA phases: 4-phases in LCA and illustrative examples.
  • More LCA aspecst: LCA limitations, LCA in product and process design, software & databases.
  • LCA in chemical engineering: questions to tackle. - Examples: material composition of a car, transport insight, PET/glass bottle, paint, bulb, bike, beer production, HDA process...

Multiobjective optimization in product and process desing: when criteria point in different directions:
  • Multiobjective optimization: scopo of MOO, MOO in supply chain.
  • MOO aproach: Pareto frontier, epsilon-constraint.
  • Case study: toy example #1 & #2.
Heat Integration:
  • Introduction to GAMS.
  • Heat integration: fundamentals.
  • Cascade diagra.
  • The transshipment model.
  • Introduction to the HEN design problem.
  • MINLP formulation for HEN design.
Molecular design:
  • Introduction to the molecular design problem.
  • Solving molecular design problems with optimization.
  • Examples of molecular design problems.
