General description and relevant information |
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
