3 Clean Technologies / Eco-innovation Make the link between technical, economic and environmental issues > Industrial development of eco-innovative projects > Life Cycle Analysis of processes > Sewage recovery Selection of the Best Available Technologies Directing of strategic choices Decision aid tool Enhancement of the value of investments /3

4 Hydrothermal technologies > A family of processes coupling Pressure and Temperature P subcritical Supercritical 22,1 MPa Point critique existing technologies 374 C T SCWO: SuperCritical Water Oxidation/ hard conditions special wastes WAO: Wet Air Oxidation special wastes /4

5 Hydrothermal technologies Temperature/pressure WAO 0,4-30 MPa Pressure too high to maintain the reaction in liquid phase C SCWO > 22,1 MPa usually around 30MPa T>374 C, Usually C Chematur - Aquacritox Waste COD g/l to assure autothermicity g/l to assure autothermicity Properties Partial solubilities of organic compounds and oxygen Limitation -> mass transfer of oxygen Reaction time minutes seconds Gas phase (exit) CO2, O2, N2, CO2, O2, N2 Liquid phase (exit) HCl, H3PO4, organic acids (acetic, formic), minerals, metal oxides, NH3, Total solubilities of organic compounds and oxygen (supercritical media) Corrosion and salt precipitation problems Minerals, metal oxides, HCl, H3PO4 in function of waste composition Materials Inox 316, Inox 304 Titanium, Inox 316L, Inconel, Hastelloy 400 C / 250 bar 1100 kg/h Hanwha Chemicals Veolia - ATHOS (Brussels, BE) 230 C / 40 bar 24 m 3 /h Bayer- LOPROX 160 C / 18 bar Catalyst Fe m 3 /h 370 C / 250 bar kg/ day

6 Wet Air Oxidation Process H2O Hydrothermal conversion Processes coupling pressure and temperature o WAO: wet air oxidation o SCWO: supercritical water oxidation 85 to 95% Organic matter 5 to 15% Liquid efflluents Compressor Pump Heat exchanger Bubble column To separation units Temperature C Pressure MPa Residence time 30min-3h COD reduction : 70% - 99,5% No NOx, SOx, furan, dioxin Potentially recoverable solid residues Potentially water recycling Very intensive process Operating cost (processes without energy integration)

7 A partnership in an R&D project : We offer Demonstrate the added value of WAO in the Oil and Gas sector. Selection of the best avalaible technology for a specific effluent : Environmental improvment (LCA) Specific experimental testing Technical and economic feasability Engineering in innovative processes
