Phenol + acetone via the Hock process (cumene peroxidation)

The route that makes ~95% of the world's phenol — and co-produces acetone, the classic two-products-from-one-feed economics. It completes the cumene story: the existing cumene-synthesis example makes cumene from benzene + propylene; this oxidizes it onward. Two atom-balanced steps: air peroxidation (cumene + O₂ → cumene hydroperoxide, CHP) at low per-pass conversion, then acid-catalyzed cleavage (CHP → phenol + acetone, near-complete). The spent air is vented, and the crude is separated by boiling point (acetone 56 C < cumene 152 C < phenol 182 C < CHP): high-purity phenol, crude acetone as the co-product, and unreacted cumene recovered for recycle. HONEST SCOPE: rigorous atom-balanced reaction stoichiometry; cumene hydroperoxide is a databank pseudo-component (no CoolProp entry) flashed under Peng-Robinson. The purification is spec-based component-split separators (the Aspen 'Sep'-block technique), not rigorous columns. The acetone product comes out ~98% because residual dissolved air (O₂/N₂) reports overhead with it — a real plant adds a light-ends/degassing column for polymer-grade acetone; phenol comes out essentially pure. Recovered cumene is shown as an open recycle stream.

Wet air oxidation of phenolic wastewater

Liquid-phase oxidation of dissolved organics in wastewater by dissolved O₂ at elevated temperature/pressure (kept liquid, not flashed to steam) — a real, widely licensed generic technology (Zimpro and equivalents), not Linde-proprietary IP, so it's built directly from the real, exactly mass-balanced combustion reaction of a standard WAO test/design compound: phenol (C₆H₅OH + 7 O₂ → 6 CO₂ + 3 H₂O). Phenol is the compound most WAO literature uses as the reference organic for design/kinetic studies, not an arbitrary choice.
