Methods of Application

Elemental Sulphur
Paratene™ D770 is designed to be used undiluted for the removal of Sulphur deposits. The system should be filled with D770 and then heated above 70°C. The solution should then be allowed to soak or circulated for 4 – 6 hours while maintaining the temperature above 70°C. Additional time may be required depending on the amount of deposit.

Thioethers
Paratene™ D770 is used undiluted at temperatures above 70°C for the removal of thioether deposits from flow lines and process equipment. The system should be filled and then either circulated or soaked for 3 – 6 hours. The contact time depends on the thickness of the deposit and the application temperature. The system should then be flushed to flush out any undissolved deposits. In some case multiple applications may be required due to flow restrictions.
We recommend adding Paratene™ D731 at concentrations of 1% to 5% with Paratene™ D770 to dissolve sulphur/thioether deposits containing organic materials such as paraffins and asphaltenes.

Safety and Handling
Paratene™ D770 contains potassium hydroxide and is very corrosive to eyes and skin. Proper protective equipment and eye protection must be worn when handling the product. Refer to the material safety data sheet for more detailed information.
