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.

View & openThermal oxidizer: VOC-laden waste-gas incineration
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.
