Application & Dosage
Specifically designed to prevent wax and paraffin deposition, RXSOL Paraffin Wax Dispersant Rx keeps them dispersed preventing downstream plugging of flowlines and formations. This unique and innovative surfactant blend also enhances penetration of existing deposits aiding in their removal.
Application of Paraffin Dispersant:
- Crude-oil production wells
- Production tubing
- Flowlines
- Gathering lines
- Crude-oil pipelines
- Transfer lines
- Storage tanks
- Crude-oil tank bottoms
- Separators
- Pumps and valves
- Wellhead equipment
- Production manifolds
- Heat exchangers handling waxy hydrocarbons
- Hydrocarbon processing equipment
- Tank and pipeline cleaning operations
- Offshore and onshore production facilities
An excellent oil soluble paraffin wax, sludge, heavy fuel oil HFO dispersant. Effectively absorbs the complete sludge and clears pipelines, tanks, etc.
RXSOL Paraffin Wax Dispersant Rx is typically applied at concentrations of 250 –1000 ppm. It can be added directly to the sludge, but it is more typically used in combination with a diluent such as a light naphtha, crude oil or aromaticsolvent. The resulting mixture is circulated for several hours until all of the sludge has been dispersed. The circulation is then stopped and the solids and water allowed to settle. The clean crude can then be pumped out of the vessel.
RXSOL Paraffin Wax Dispersant Rx can be combined with Rxsol PPD depending on composition of the deposit to achieve maximum effectiveness.
Typical starting range:
- For pipelines, equipment or isolated sections containing hardened paraffin deposits:
- Remove free oil where operationally appropriate.
- Introduce Paraffin Wax Dispersant neat or diluted in a compatible hydrocarbon solvent.
- Ensure maximum contact with the wax deposit.
- Allow sufficient soaking time.
- Circulate where possible to increase mass transfer.
- Flush displaced wax and contaminated solution from the system.
- For continuous treatment, Paraffin Wax Dispersant may be injected using a chemical dosing pump.
- The injection point should preferably be located:
- Upstream of the wax deposition zone
- At the wellhead
- Downhole where technically suitable
- Upstream of flowline restrictions
- Before pipeline temperature falls substantially below WAT
- Upstream of separators or transfer systems where wax deposition is observed
- Uniform distribution of the chemical in the crude oil is important for maximum effectiveness.
- Determine the approximate amount and location of wax accumulation.
- Where practical, mechanically remove excessive bulk deposits before chemical treatment.
- Introduce the product neat or diluted with a compatible hydrocarbon solvent.
- Circulate the cleaning solution through the affected section.
- Maintain adequate contact time.
- Moderate heating, where equipment and operating procedures permit, can substantially improve wax dissolution.
- Continue circulation until the required flow improvement or deposit removal is obtained.
- Displace the spent cleaning solution and loosened wax into an appropriate recovery system.
- Laboratory testing is recommended before large-scale treatment.
- Sprayed onto wax deposits
- Added to a hydrocarbon circulation medium
- Recirculated through the tank
- Applied as part of a soak-and-circulate cleaning procedure
