2 Voraxial Separator Benefits No Pressure Drop provides a pressure increase High G force Separation of 3 components simultaneously High flow, small footprint Treats a wide range of flows, even slugging flows High performance over a wide concentration range High performance over a wide flow range Low shear impeller oils are not emulsified Non-clogging open impeller Variable speeds to optimize separation Scaleable

3 Voraxial Separator is Scalable The Voraxial Separator models Model Diameter Typical GPM Voraxial Voraxial Voraxial Voraxial ,000-3,500

5 Voraxial 8000 Separator View of Open Impeller - 8 Diameter Separation Chamber - Treats up to 100,000 BPD

6 Benefits of Technology Improvement Modification of Rotor Assembly Non-contacting, dry running technology High performance sealing & extended seal life High operating speed 6000 to 7000 rpm Increased G force over 300% Separation of 4 Components: L/L/S/G Improvement in Separator reliability Decrease in maintenance requirements

8 Technology Comparison VORAXIAL Hydrocyclones Gas Flotation Footprint Small Moderate Moderate Utilities Electrical Motor for Impeller Works off pressure drop Electrical high flow pump for induced gas. Sensitivities Low shear impeller does not re-emulsify emulsify oil droplets Sensitive to emulsion and oil droplets One unit to separate solids and liquids. Not Sensitive to flow rate or concentration changes Requires large pressure drop Sensitive to emulsion and oil droplet size Typically use separate units to separate solids and oil. Internal cone wear can be high Sensitive Sensitive to flow rate and concentration fluctuations Pump wear from solids Induction of inadequate gas Sensitive to emulsions and small droplets Will often need upstream chemical addition to get good performance Sensitive Sensitive to concentration increases Pressure Drop None Very high to create necessary G sg Small

14 Voraxial 2000 Skid

15 Complete Solution to <10ppm Oil Voraxial Produced Water Skids First stage Voraxial for bulk oil and solids separation Typically removes 50% to 90% of the oil depending on the droplet size, emulsions, etc. Second stage is the Coalescer Coalesces small droplets of <5microns to larger droplets for improves separation see previous graph Third stage is the second Voraxial to remove most of the remaining oil Typically outlet from second Voraxial is 20 to 30ppm oil or less Fourth stage polishing Solids filter followed by media to remove oil to <10ppm

18 Additional Results Performance not affected by changes in flow over a range of 2 to 1 Performance not affected by influent concentrations over a range of approximately 17 to 1

19 Polishing System Removes the final few ppm to meet <10ppm oil Media in filter cartridges or supplied as bulk media Removes 1 to 1.5 kg of oil per kg of media Removes fine droplets and emulsified oil Top to bottom flow or from outside to inside

20 Polishing, Option 2 Chemical injection on outlet of coalescer can be used Usually cationic water clarifier Approximate equivalent annual cost to solid media $50 to $100k/yr chemical consumption

21 Produced Water Skid Flexible design to provide only what is needed for each application Polishing is not always needed Solids separation is not always needed Does not necessarily need to be a skid Components can be shipped individually Individual units can be used to replace CPI or other separators Used in front of IGF or Hydrocyclones to remove solids and bulk oil Eliminates surges and improves performance of existing equipment Polishing systems available Media installed in filters or supplied as bulk

22 Voraxial 2000 Skid Testing with Gas Slugging Oil concentration varies from 0.5% to 2% Solids concentration - nominal Gas slugging up to 100% without any interference to separation performance No effect on Separation Performance

23 Project Skimmer With Oil Voraxial 1000 Separator Oil Skimmer located in pond to skim oil Voraxial connected to Skimmer. Oil is collected; water discharged back into pond

24 Oil field Applications Produced Water - Offshore and Onshore Transocean Deckwater Drainage System 2-way and 3-Way 3 Separation Tar Sands Applications Refinery Industry Pre and Post Treatment for API Separator. Pipeline De-Commissioning Pre-treatment to IGF, DGF, Hydrocyclone,, etc Bulk Separation, Including Liquid/Liquid, Liquid/Solid and Liquid/Liquid/Solid

25 Summary No Pressure Drop Produces a high G force Flexible Has high separation efficiency Has higher reliability, lower maintenance Has a lower energy consumption per flow rate Performance not affected by flow over wide range Performance not affected by concentration over a wide range Separates 4 components simultaneously
