Aspen Plus Notebook (Example)

This is a benchmark example entry in the Field Notes library.

The problem: In an ethanol-to-olefins concept model, should the next design sprint prioritize conversion yield or utility intensity?

The framing: System boundary, basis, and key assumptions are stated before detailed modeling.

The check: Carbon and utility reasonableness checks are applied before trusting simulation outputs.

The test: Reversal conditions are explicit: if selectivity drops below 72% or utility economics shift materially, the recommendation changes.

This example shows how to identify a binding operating constraint before over-investing in simulation detail.

What makes this entry strong:

• The decision question is stated before any calculation.
• Assumptions are named with failure conditions, not just listed.
• The math is checked against physical intuition.
• The recommendation includes explicit conditions for revision.
