2 Understanding what's important to you Water is an important utility in many day-to-day refinery activities. As in all sectors, key water and wastewater management objectives are: Safety Compliance Reliability Guarantees Quality service Efficiency and aligning our resources to meet your needs With a lot of references in the Oil and Gas industry and a dedicated pool of design, construction and operations experts, Veolia Water develops water and wastewater treatment solutions worldwide. Specialists from the refining business Dedicated process expertise group Over 300 research and development staff Proprietary technologies (2, 500 patents) Operations in over 55 countries NPRA Safety Excellence Award Wastewater Process water Residuals management Veolia Water Oil and Gas 2

Whether it is potable water for human consumption, in-process water for production, or utility water for boiler feed or cooling tower makeup, Veolia Water can help.

3 Process water Typical Process Water Treatment Water is an important agent in many of the day-to-day refinery activities. As such, it is critical that the delivery of this agent be reliable, high in quality and consistent timeliness. Whether it is potable water for human consumption, in-process water for production, or utility water for boiler feed or cooling tower makeup, Veolia Water can help. Whether the water comes from a well, a river, a lake, the sea or an ocean, Veolia Water can offer the most appropriate technology for the application - frequently a proprietary technology. Sea water desalination Demineralization Cooling water treatment Thermal technologies: Multi-Stage Flash (MSF) Multi-Effect Distillation (MED) Mechanical Vapor Compression (MVC) Ion Exchange technology with counter-current regeneration Reverse Osmosis (RO) systems Condensate mixed-bed polishers Chemical dosing systems for boiler feed water Deaerators Flocculation/sedimentation Media filtration Activated carbon Hardness removal Chemical treatment systems and chemical supply For example: Actiflo TM The pre-engineered Actiflo TM system is a compact standard package plant for drinking water, process water and wastewater treatment. The process is a highly efficient and proven clarification technology, which uses a microsand ballast that functions as a seed, enhancing floc formation and settling. A process video is available at: Veolia Water Oil and Gas 3

Wastewater Typical Wastewater Treatment The processing of crude oil, from the desalter to the hydrotreater and most steps in between generates wastewater.

Veolia Water has numerous technologies available for the treatment of crude processing wastewater, ranging from simple oil / water separation to biological treatment and polishing prior to final

4 Wastewater Typical Wastewater Treatment The processing of crude oil, from the desalter to the hydrotreater and most steps in between generates wastewater. Wastewater must be treated prior to discharge or re-use. In either case, the treated wastewater must meet specially prescribed criteria - either regulatory driven or process mandated. Veolia Water has numerous technologies available for the treatment of crude processing wastewater, ranging from simple oil / water separation to biological treatment and polishing prior to final discharge. For example: Bio-Denipho TM A/O System Process Schematic The Bio-Denipho TM technology is the application of the Anaerobic/Oxic (A/O) process in an oxidation ditch layout and consists of a staged Block and Hong Anaerobic Selector followed by single or multiple oxidation ditches. The anaerobic selector performs two functions for effective treatment: filament control and biological phosphorus removal. Upon expansion, nitrogen removal can be incorporated into the treatment scheme by adding anoxic tanks and operating as an A 2 /O ditch. Oily wastewater treatment Reuse / recycling Zero liquid discharge TiPSS (Tilted Plate Separator Systems) for oil/water separation Coagulation and flocculation Floatation systems (induced air/gas, dissolved air/gas) Walnut shell and media filtration Warm lime softening Biological treatment (activated sludge, bio-filters, membrane bioreactors) VOC removal (Activated carbon treatment) Sludge management (de-watering, incineration) Coagulation, flocculation, sedimentation Membrane technologies: continuous micro/ultra filtration, nano filtration, reverse osmosis Sand filtration Evapo-crystallization (Fluorides and salts) Veolia Water Oil and Gas 4

Residuals management Veolia Water has proprietary and licensed technologies and processes that do more than simply treat for disposal:

For example: HARDTAC Veolia Water maintains an exclusive worldwide crystallization technology license from DuPont.

$CaF 2 + 2 KOH For example: Sludge treatment duct cooling water flue gas refractory lining freeboard fuel sand fluid bed wet sludge$ wind box fluidization air arch Pre-treatment (two-phase or three-phase centrifuge) Filter press, belt filter Fluidilized bed

wind box fluidization air arch Pre-treatment (two-phase or three-phase centrifuge) Filter press, belt filter Fluidilized bed

5 Residuals management Veolia Water has proprietary and licensed technologies and processes that do more than simply treat for disposal: these technologies allow you to convert waste to product that may be reused or injected into the coker. For example: HARDTAC Veolia Water maintains an exclusive worldwide crystallization technology license from DuPont. The recovery and reuse of KOH from HF alkylation processes is accomplished by this equation: 2KF + Ca (OH) 2 The use of this licensed crystallization process: Allows recovery and repurchase of regenerated KOH Avoids the expense associated with hazardous waste disposal CaF KOH For example: Sludge treatment duct cooling water flue gas refractory lining freeboard fuel sand fluid bed wet sludge wind box fluidization air arch Pre-treatment (two-phase or three-phase centrifuge) Filter press, belt filter Fluidilized bed incineration Slops, bottom oil: separation For example: Coker injection The movement and management of slop oil in a refinery is frequently inefficient and costly. Veolia Water has an efficient model incorporating a patented process that: Provides a "process owner" Inventories and monitors tank solids content Establishes "tank specific" solids content limits Implements three-phase separation of slop oil Allows injection of solids to coker Veolia Water Oil and Gas 5
