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. Honesty note: the 95% phenol destruction used here is representative of published WAO performance at adequate severity, not a fitted rate law -- there is no cited kinetic model in this codebase for phenol WAO, so (matching the fixed-conversion-reactor posture used throughout this codebase when kinetics aren't available) this is a fixed-conversion reactor, not an Arrhenius rate expression.
