About Petromax Products

Petromax products 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.

3

This application is a combination of specific chemical components and related mechanical applications.

Applications focus on waste handling minimization and rapid sludge mobilization both at the point of application and down stream.

Afterthe application the oil is floating on top of the water. The oil is removed from the soil in secondsand will not re-attach to the solidswithin the aqueous phase.

An Environmental Breakthrough for the Oil and Tar Sands Bitumen Recovery Industry

• The following slides are from ongoing work related to the oil sands and tar sands petroleum industry.

• The objective is to utilize a Petromax cold water process to remove bitumen in both water-wet and oil-wet conditions.

• Further, such a Petromax sand 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.

Crude Sludge Mobilization, both up stream and down stream, is typically the first problem encountered in crude waste handling. The final objectiveis often focused on remediation and recovery and therefore Petromax seeks to optimize at each step along the way.

A few key enhancements gained from our application:

* 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.

Recovery or Disposal?

One opportunity for recovery is to enhance a decanter or centrifuge operation. Thatis to say, the crude sludge that has been mobilized with a Petromax application willhave already started the oil, water, solids separation process and will continue to doso 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 resultingcake will be more liquid free and cleaner.

Inline Injection Module

18

The Petromax conditioned crude sludge that will be held in secondary containment (awaiting the decanting/centrifugeprocess) will remain mobilized for easy transferring to a mixtank.

The footprint of such an operation will be smaller since the waste stream has been significantly minimized as comparedto a conventional waste handling process.

Solids/Liquid Separation Sludge Testing

Tests completed by US Filter showed that Petromax conditionedsludge did not require the addition of polymers during a dewateringprocess. This allows the dewatering technician to more easily dial-inhis 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%.

• Crude sludges of this nature are particularly problematic to handle.

• Conventionally, a combination of heat, a diluent, and high volume circulation are used to blend and transfer these types of sludges. Some heavies will remain in a tank and entry will be required for sludge removal prior to inspection.

• Petromax utilizes a low volume micro encapsulation application (without the use of heat) to rapidly mobilize, within seconds, and remove this type of sludge.

Paraffin and Asphaltene Sludges

21

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.

The result is a very pumpable slurry

without added heat to the application.

This is successful water-based applicationon a very waxy crude sludge sample from Petronas refinery in Malaysia.

23

Since there are variations from one sludge toanother we must test representative samplesto determine proper formulation.

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.

28

• Petromax Sludge Conditionng is a waste minimization process without the cost of dewatering when taken to a coker unit.

• Fewer temporary storage tanks are required.

• Conditioned sludge remains suspended and pumpable throughout the 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.
