* The efficiency test was carried out with a deviation from thestandard, in order to obtain stricter conditions, the gas-condensate medium in the flasks was heated to +22 ˚С, the rods were cooled to a temperature of (minus) -3˚С. That is, the standard temperature difference was 25 degrees, and not 10, as described in the “COLDFINGER” method (gas condensate – 5 ˚С above the solidification temperature, and rods – 5 ˚С below the solidification temperature).

The total inhibitor consumption per ton of paraffinized condensate does not exceed 300-1000ppm.

Aromatic class hydrocarbons are used as paraffin solvents. The optimal proportion of solvent for dissolving paraffin is 1:5 without adding an inhibitor.

To ensure economy of solvents of the aromatic series, it is proposed to use a 0.5-1.0% solution of modifiers in aromatic hydrocarbons, which allows to reduce the solvent consumption by more than 2.5 times, reduce the reaction time of dissolving paraffins, and consequently the time for the unit operation

All products are manufactured in accordance with the approved specifications, meeting all quality and efficiency requirements, and are sold only after careful analysis of the quality of both raw materials and finished products.

Each manufactured batch is accompanied by original quality passports.
