Introduction to Chemical Engineering-II

Doesn’t dodge the messy bits, but the labs assume you’ve already got MATLAB and Aspen wired up; that tripped me for an hour. After that, the material clicked. The McCabe–Thiele walkthrough in the distillation chapter stuck, especially the moment where they force a bad reflux choice and show the stage count blow up. That’s the kind of failure-mode thinking I expect in prod, not just tidy equations. The heat exchanger section tying LMTD back to fouling felt like infra obs, not theory. I’m not shipping PRs for k8s here, but the arch thinking translates. It nudged my baseline from “adequate” toward actually competent without pretending chemicalpharmaceutical work is clean.

the McCabe-Thiele distillation lecture stuck; the VLE plot clicked, but I wasn't sold on the rushed reactor design homework.

The bias toward doing things the right way instead of shortcut math shows up early, which I tend to value when material bleeds into real systems. It frames Chem Eng II less as plug-and-chug and more like an arch problem, mapping assumptions, constraints, and failure modes—similar to how prod infra behaves when RPS spikes. The moment that stuck was Chapter 4’s McCabe–Thiele walkthrough on benzene–toluene, especially the step where the operating line shifts after changing reflux; that’s the kind of concrete knob-turning I remember. Mostly works, though I wasn't sold on the pacing around mass transfer coefficients; it jumps a bit and could use one more sanity-check example. There’s a steady emphasis on checking units and bounds, which felt like CI for equations, not flashy but keeps bad PRs out of the repo. It got across ideas I usually end up pulling from a senior in the hallway, minus the calendar ping.
