Capstone: Pinch Analysis Diagnostics
Hands-on: diagnose eight process-integration call-outs — cross-pinch heat transfer, infeasible matches, wrong utility placement, threshold problems and over-complicated networks — then calculate, verify and prescribe the fix.

You've learned to classify streams, build composite curves, run the problem table algorithm, apply the golden rules, match and split streams into a feasible network, target the minimum number of units, and choose ΔTmin economically. This capstone puts you in the role of the process integration engineer — targeting new designs and auditing existing plants against the numbers this method gives you. The thread through every case: find the true minimum utility target before designing anything, and never let heat cross the pinch. Most of the value in this discipline comes from two things — calculating a number nobody had calculated before, and spotting a violation of a rule that's easy to state but easy to miss on a real,…
