PRA^® Application Instructions

Downhole Situations

1. Apply Plutus PRA^® down the annulus at an initial rate of 12,5 litres per 100 metres (1 US gallons per 100 ft) of well depth to 2,500 metres (8000 ft). Wells deeper than 2,5000 metres should receive 18,5 litres per 100 metres (1.5 US gallons per 100ft) of total depth. Combine with crude from the well if desired. Do not add refined hydrocarbons. Greater volume may be required based on severity of paraffin accumulation.
2. Allow Plutus PRA^® to circulate overnight if possible to clean pump and tubing or at least for two complete rotations of tubing volume. The wax will recombine with the oil and stay in solution until the refining process occurs.
3. Perforations usually open when Plutus PRA^® is allowed to stand for a period determined by the severity of the build- up. 24 - 48 hours is normal.
4. If an unacceptable amount of build-up still remains, repeat steps 2 - 3 until satisfactory.

Note: regular use of Plutus PRA^® will lessen the frequency of downtime and maintenance.

Pipelines

1. Plutus PRA^® should be injected into the pipeline as far upstream as possible. Injected volume will depend upon severity of wax build- up in the pipeline.
2. PRA^® treated pipelines from production facilities will have less build-up than from untreated wells. Pumps stay clean and valves function properly. Less pressure may be needed to move product.

Note: Subsea and cold climate pipelines have less friction when treated with Plutus PRA^®. Pigging or scraping problems are eliminated or reduced in kinked lines.

Barges, Tankers, Wagons & Storage Batteries

1. Plutus PRA^® should be added to “dirty” tanks at 2 - 5% of the volume of the sludge accumulation.
2. Circulate Plutus PRA^® in storage tanks if time and storage conditions allow. Circulation will separate wax from the sludge. The wax will re-enter the oil phase of the crude without change in the grade of the crude. Add water when the tank is pulled down for scheduled maintenance. The bottoms may then be pumped off with little or no hydrocarbons remaining.

Note: It is not necessary to take barge or tanker compartments out of service. Normal current movement within the oil will serve to circulate the Plutus PRA^® and reduce sludge or wax volume.

Fuel Storage Tanks

1. Plutus PRA^® should be added to diesel or gasoline tanks at 0,4 – 1 litre per cubic meter (2-5 US gallons per 5,000 gallon) of tank capacity.
2. Circulate Plutus PRA^® to kill algae and mould or to break suspensions. Circulation will cause solids and water droplets to fall out of suspension. Drawdown is not required. Fuel quality and BTU value will increase. Effective treatment time is generally within 24 hours.

Note: Before beginning any treatment process, make sure all Safety Guidelines and Procedures are in place. If in doubt about correct procedure, check with Safety Officer or OSHA before proceeding. The producer, Plutus Environmental Technologies Inc. or its associated or subsidiary companies shall not be held liable or at risk for any safety violations or errors by the user.
