Paraffin Deposit Inhibitor POLYDEX® AP 07

Technical Requirements TU 2458-091-53501222-2013

Purpose of Use

Paraffin deposit inhibitor POLYDEX® AP 07 is specially designed for crude oil treatment.

Paraffin deposit inhibitor POLYDEX® AP 07 influences paraffin crystal growth directly and due to its molecular structure the inhibitor has dispersive power which keeps paraffin crystals in a suspended state. It solves the problem of residual emulsion which can transport paraffin crystals into storage facility tanks.

Application Area

  • Prevention of paraffin deposits in oil wells.
  • Prevention of paraffin deposits in oil and gas condensate production lines and pipelines.
  • Protection of equipment, storage tanks, etc. from paraffin deposits.


Two grades of POLYDEX® AP 07 are available: A and V.


POLYDEX® AP 07 grade –ź

POLYDEX® AP 07 grade V

Conditions of application

Complicated conditions

Standard conditions  

Customer Benefits      

  • Possibility to eliminate mechanical cleanings from paraffin deposits.
  • The inhibitor does not influence oil treatment (oil processing).
  • The inhibitor is stable under high temperatures and high pressure.
  • High efficiency of the inhibitor allows to reduce its consumption.
  • The inhibitor is compatible with other chemicals.
  • Low freezing temperature of the inhibitor.

Process Technique

Paraffin deposit inhibitor POLYDEX® AP 07 is to be injected continuously and with a dosing pump before the point where crystallization of paraffin starts.

The consumption of the inhibitor is to be determined with laboratory tests. The consumption depends on the crude type, the temperature conditions, and the tasks to be performed. It may vary from several grams to several hundreds of grams per m3.

To select the optimal design of application and consumption rate of paraffin deposit inhibitor POLYDEX® AP 07 it is recommended to contact our specialists.
