Ecuador Amazon Region Hydro blasting Petromaxinto crude tank sludge samples to mobilize the sludge and eliminate sticking to surfaces

3. About Petromax Products Breaking water out of produced oil • Petromaxproducts are • water-based proprietary • non-toxic, • non-flammable, and • environmentally safe formulations • designed to remove hydrocarbons from surfaces in such a manner as to not allow the oils to re-attach. Breaking mature fine tailings emulsion from Suncor’s Pond One in Alberta, Canada

4. Petromaxapplications are a combination of • specific chemical components and • related mechanical applications. Petromax tailing pond remediation testing at the University of Southern California USA Environmental Laboratory

5. Categories of Use Before After • Crude tanks • Waste pits & Lagoons • Railcars • Tankers • Surface cleaning • Sand cleaning Unocal Remediation Effort at Guadalupe Beach, CA , USA Valero Refinery, Wilmington, CA , USA Tank Cleaning

6. Resource remediation and recovery are evaluated as part of any solution and a Petromaxapplication may be combined with conventional technologies to enhance their existing processes.

7. Petromaxcan be utilized to enhance, or de-bottleneck, existing sophisticated sludge handling/remediation facilities ........ aimed also at improving end products and disposal components. Initial testing introduced by hydro blasting sludge in enclosed 5 gallon buckets followed by bench top centrifuging.

8. Cleaning Clays in Ecuador Lab testing oil contaminated clays for hydro carbon removal at ambient temperature ……… at the University in Ambato, Ecuador This laboratory clay sample testing was conducted using Petromaxand a hand held mixer at ambient temperature.

10. Cleaning Soils in Ecuador 1 Oil contaminated soil 2 Hydro blasting with Petromaxsolution 3 Oil rises to water surface Recovered Sand & Clays Preparing to do a field sample test using a hydro blaster In this field test the oil has been hydro blasted off the soil with a Petromaxwater-based solution at ambient temperature. After the application the oil is floating on top of the water. The oil is removed from the soil in seconds and will not re-attach to the solids within the aqueous solution.

11. An Environmental Breakthrough for the Oil and Tar Sands Bitumen Recovery Industry • The following two slides are from ongoing work related to the oil sands and tar sands petroleum industry. • The objective is to utilize a Petromaxcold water process to remove bitumen in both water-wet and oil-wet conditions. • Further, such a Petromaxsand cleaning/oil recovery process will not create a tailings emulsion. • Water recovery, soils/clay compaction, and energy savings becomes a dramatic plus over the current process in Alberta, Canada.

The removal of hydrocarbons (light oils) was accomplished in less than a minute using a water-based formula at ambient temperature.

15. Crude Sludge Mobilization, both up stream and down stream, is typically the first problem encountered in crude waste handling. The final objective is often focused on remediation and recovery and therefore Petromaxseeks to optimize at each step along the way. A few key enhancements gained from our application as listed below: • Once the crude sludge is mobilized/conditioned it will not stick within hoses or secondary containment. • The minimized waste stream will remain suspended and pumpable. • Heat is not required as part of the application. • If inorganics are within the waste stream then partial cleaning of these solids will have already began.

17. What is clean-up going to be like?

18. Recovery or Disposal? One opportunity for recovery is to enhance a decanter or centrifuge operation. That is to say, the crude sludge that has been mobilized with a Petromaxapplication will have already started the oil, water, solids separation process and will continue to do so in a mix tank just prior to the mechanical separation equipment or with added inline shearing. The mechanical separation process will now be more efficient. The resulting cake will be more liquid free and cleaner.

19. Oil Recovery Secondary Containment • The Petromaxconditioned crude sludge that will be held in secondary containment (awaiting the decanting/centrifuge process) will remain mobilized for easy transferring to a mix tank. • The footprint of such an operation will be smaller since the waste stream has been significantly minimized as compared to a conventional waste handling process.

20. Solids/Liquid Separation Sludge Testing Tests completed by US Filter showed that Petromaxconditioned sludge did not require the addition of polymers during a dewatering process. This allows the dewatering technician to more easily dial-in his process, as well as, reduce the dewatering costs. The net results, as tested by US Filter on their dewatering equipment, yielded a significantly drier cake. Instead of the usual 30% to 40%liquid content on typical filter tests, the conditioned sludge yielded result of 17.5%.

21. Paraffin and Asphaltene Sludge Crude sludge of this nature are particularly problematic to handle. Conventionally, a combination of heat, diluents, and high volume circulation are used to blend and transfer these types of sludge. Some heavies will remain in a tank and entry will be required for sludge removal prior to inspection. Petromaxutilizes a low volume micro encapsulation application (without the use of heat) to rapidly mobilize, within seconds, and remove this type of sludge.

22. What are we trying to accomplish with these tough sludges? • Our chemical solution is water-based (does not contain surfactants) and does not mix with the crude, nor do we want it to. • What we have done is rely upon the hydro blasting pressure and close proximity chemical impact to break up the paraffin or asphalt sludge for the purpose of encapsulation.

23. The result is a very pumpable slurry without added heat to the application. This is a successful water-based application on a very waxy crude sludge sample from Petronas refinery in Malaysia.

24. Since there are variations from one sludge to another we must test representative samples to determine proper formulation. Ongoing sample testing Pemex Salinas Refinery, Mexico

28. Coker Unit Crude Sludge Recovery Within an oil refinery both T&D and handling costs for crude waste streams are high. • Conventional methods of sludge removal and processing are both manpower and equipment intensive. • These methods create costly repetitive and laborious activities. • When such methods are utilized, the sludge literally has to be double handled (again outside the tank) at a cost significantly greater than the original removal cost.

29. Petromaxadvantages of disposing to a refinery coker: • PetromaxSludge Conditioning is a waste minimization process without the cost of dewatering when taken to a refinery coker unit. • Fewer temporary storage tanks are required. • Conditioned sludge remains suspended and pumpable throughout the refinery coker injection transfer schedule. • Time consuming and additional waste generating vacuum truck wash outs are all but eliminated. • The conditioned sludge handling application allows the operational tank to be returned to service safer, faster, and in oil free condition.
