IDAES + Pyomo process flowsheets - REE recovery, leaching, solvent extraction, diafiltration. Live IPOPT solve is the default tier (~seconds); bake / cache / surrogate land in later phases. Refusals are 200 OK responses with a code, not error paths.
Flowsheet coverage
CMI (Critical Materials Innovation) rare-earth-magnet recycling: Nd2Fe14B feed → copper-nitrate dissolution → S/L filter → pH adjustment → oxalate precipitation → S/L filter → calcination to Nd2O3. A hydrometallurgical alternative to UKy's primary recovery and to hydrogen decrepitation's physical pre-treatment.

Two-salt diafiltration (LiCl + CoCl2) through a single membrane module. Feed + diafiltrate mix, contact the membrane, and split into a retentate (Co-enriched) + permeate (Li-enriched). The separation target is high Li recovery in the permeate with low Co contamination.

Get started
These run live IDAES + IPOPT solves through the agent. The first few are quick single-point solves; the later ones sweep, optimize, or compare recovery routes.

KPIs

Hydrogen decrepitation of end-of-life NdFeB permanent magnets from HDDs: 2.5"/3.5" drives → shredder → H2-atmosphere furnace at ~170°C / 1 atm. The H2 ingress fractures the magnet matrix into friable powder, the canonical first step in REPM recycling. Reports Nd2Fe14B recovery, H2 consumption, furnace size, and heat duty.

Multi-stage Li/Co diafiltration cascade with precipitators. Unlike the single-module 'diafiltration' flowsheet, this is a cost-minimization: the cascade DOF is unfixed and IPOPT picks the cheapest operating point (membrane areas, feed splits) that clears the requested Li/Co precipitator-recovery floors. Tune cascade size (stages/tubes), feed, and recovery targets.
