Description
Dewaxol™ series chemicals for removal of asphalt, resin and paraffin deposits (ARPD) are designed for prevention and washing off ARPD from oil pipelines, downhole and oilfield equipment, reservoirs, and reduction of hydrocarbon pour point in oil production and transportation processes.
Depending on the purpose, several brands of chemicals are produced:
- Dewaxol™ 7201 is an ARPD inhibitor designed for prevention of ARPD formation. It is used as a wax crystal modifier in the crystallization centers to prevent their further growth;
- Dewaxol™ 7315 is a depressant designed to reduced the pour point of oil with a high paraffin hydrocarbon content;
- Dewaxol™ 7504 is an ARPD dispersant designed for removal of ARPD from wells, oil pipelines, reservoirs, oil field equipment. It exhibits high penetrating, dispersive and washing power. It forms a film on the surface of metal, preventing further paraffin and asphaltene deposition;
- Dewaxol™ 7604 is an ARPD solvent designed for flushing of oil pipelines, downhole and oil field equipment from ARPD deposits.
Application
Dewaxol™ 7201, constant injection into the fluid stream with dosages of 100 to 500 g/ton. The optimum dose is determined based on the results of pilot industrial tests.
Dewaxol™ 7315, constant injection into the fluid stream with dosages of 30 to 500 g/ton. The optimum dose is determined based on the results of pilot industrial tests.
Dewaxol™ 7504, dosing at concentrations ranging from 0,5 to 5% into the stream of hot oil or hydrocarbon solvent, which is used for cleaning of oil field equipment.
Dewaxol™ 7604 is used for equipment cleaning, it is not added into the oil.
Transportation and storage
