Rheological depressant additive Para DR3225

Rheological depressant additive “Para DR 3225” is a specially selected combination of copolymers in a hydrocarbon solvent and is designed to improve the rheological properties of oil during transportation through infield facilities. Improvement of rheological properties affects the depression of the pour point of oil. Additive “Para DR 3225” is produced in accordance with the current technical specifications TU 2458-013-17423242-2008 with amendments 1, 2, 3.

Transportation of oil and oil products


Additive “Para DR 3225”: is fed directly into the oil, usually after heating. Warming up the additive is especially necessary in winter conditions. It is possible to pre-prepare the working solution of the additive in a hydrocarbon solvent, followed by the supply of the additive in the form of a working solution. The additive can be used not only in prepared oil, but also in a water-oil emulsion.


The effectiveness of “Para DR 3225” depends on the type of oil being processed. The dosage of the additive depends on the specific conditions and the required rheological parameters of the oil pumped through the pipeline. Typical dosages can be considered 200-400 g/ton. It is recommended to supply the additive with a dosing pump.
