Paratene™ S620

Paratene™ S620
Paraffin Dispersant

Technical Data Sheet


Paratene™ S620 is a solvent based blend of anionic and non-ionic surfactants designed to disperse sludge deposits found within crude oil storage vessels, pipelines and well tubulars.

Paratene™ S620, when mixed and circulated with hydrocarbon sludge, will aid in converting the sludge back into a marketable crude oil.

Typical sludge deposits are composed of a mixture of waxes, asphaltenes, water, light hydrocarbons and solids. Paratene™ S620 acts to disrupt paraffin micelles that constitute the major source of viscosity for most typical hydrocarbon sludge.

Paratene™ S620 is produced in a highly concentrated form and is typically applied at a rate in the order of 500 ppm based on the sludge volume.

Features and Advantages
- Permits the recovery of crude oil from tank bottom sludge
- Acts as a pour point inhibitor for some waxy crude oils.
- Promotes solids settling and demulsification.
- Contains no products detrimental to refinery operations.
- Excellent wax dispersant for oil well clean-outs.

Typical Physical Properties

Methods of Application
Paratene™ S620 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 light naphtha, crude oil or an aromatic solvent. 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 are allowed to settle. The clean crude can then be pumped out of the vessel.

For oil and gas well clean-outs, Paratene™ S620 is applied by batch or squeeze methods in concentrations between 250 – 20,000 ppm within an aromatic solvent.

Paratene™ S620 can be combined with other Paratene™ products depending on composition of the sludge deposit to achieve maximum effectiveness. Consult with the Woodrising laboratory to determine the best application for your problem.

Safety and Handling
Paratene™ S620 is a combustible liquid. Avoid contact with heat and open flames. Always handle with gloves and eye protection. Refer to the material safety data sheet for more detailed information.
