Thermal oxidizer: VOC-laden waste-gas incineration — a PENG-ROBINSON process flowsheet
A dilute VOC-laden air stream preheats and combusts completely at typical thermal-oxidizer operating temperature (~1100 K / 827degC, in the 750-870degC range these units commonly run at for reliable VOC destruction), destroying toluene (a standard VOC surrogate) to CO₂ + H₂O (C₇H₈ + 9 O₂ → 7 CO₂ + 4 H₂O, exactly mass-balanced) at 99.9% destruction-and-removal efficiency (DRE) — the real regulatory benchmark figure widely cited for thermal oxidizers/incinerators (e.g. the hazardous-waste-incinerator DRE standard), not a fabricated number. This is generic combustion-based air-pollution-control technology, not Linde-proprietary IP — built the same way already models fuel-gas combustion, applied here to a waste-destruction duty instead of a process-heating duty.
Modeling assumptions & limitations
- 1No NOx formation chemistry is modeled (matching fired_heater's own disclosed bounded scope), and heat recovery (regenerative/recuperative preheat of the incoming waste-gas stream, standard on real thermal oxidizers to cut fuel demand) isn't modeled — the preheat duty here is a plain utility heater, not a heat-integrated exchanger.

Flue-gas desulfurization: venturi wet scrubber
A coal/oil-fired power-plant stack gas (SO₂ in a hot N₂/CO₂/O₂/water flue) is cleaned in a high-energy venturi wet scrubber before the stack — the classic flue-gas-desulfurization (FGD) front end. The new venturi_scrubber unit op accelerates the gas through a throat where injected scrubbing water is atomized, and a stated fraction of the soluble SO₂ is absorbed into the drops and carried out as a slurry while the cleaned gas goes up the stack. Two cited pieces are computed: the momentum-exchange pressure drop ΔP = ρ_L·(Q_L/Q_G)·v_gt² (Calvert 1968; de Nevers — the L/G here is ~1.4 L/m³ and the throat runs 90 m/s, giving ~11 kPa, a real high-energy venturi), and the SO₂ removal (92% at this water rate) that drops the stack SO₂ to a fraction of the inlet.
Polymerization reactor comparison: CSTR cascade vs. tubular (PFR)
The same monomer feed, split 50/50 into two trains at equal total reactor volume: a 3-stage CSTR cascade (each stage blending its own new polymer with the MWD already carried by the stream from the stage before it) versus a single tubular (PFR) reactor. Both converge to a real, different Mn/Mw/PDI — the PFR reaches higher conversion at the same total volume, but its cumulative polydispersity is measurably broader than the cascade's, because chain length drifts continuously with conversion along the tube while each CSTR stage makes its own local production under one fixed monomer concentration. See the 'Polymerization Reactors' docs page for the full reasoning.
Helium liquefaction (Linde-Hampson cycle)
A Joule-Thomson liquefaction loop: helium is compressed, aftercooled, precooled well below its ~40-51 K JT-inversion temperature, then throttled through a valve into a flash drum that draws off liquid helium while the cold vapor recycles back to the compressor suction — the same JT-cycle physics as the platform's LNG/refrigeration loops, run on a fluid whose inversion curve makes precooling mandatory before the throttle can cool it at all.
Cement kiln calcination + CO2 liquefaction
Preheated limestone (CaCO₃) enters an indirectly-heated rotary kiln that calcines it toward CaO, releasing a CO₂-rich off-gas; the gas passes a knockout drum, then is compressed and cooled to liquefy the CO₂ for transport/storage.
NGL fractionation: single-shell Petlyuk dividing-wall column
A natural-gas-liquids cut (ethane / propane / n-butane) split into three on-spec products by ONE thermally-coupled dividing-wall column instead of two columns in series. This uses the native Petlyuk unit op: a prefractionator whose reflux and boilup are supplied by the main column (the single condenser + single reboiler), solved by an outer Wegstein loop that converges the bidirectional vapor/liquid coupling to self-consistency — the coupling legacy sequential-modular solvers approximate with two connected columns whose recycle fails to converge.
