Description
Suspension of ultra-high molecular weight polymers in a special combined carrier (non-solvent). It is used for transporting oil, heavy oil, for transporting diesel fuel and gas condensate. Depending on the grade, the composition of the product includes indirect materials:
- SNITREN™ grades 1110, 1111, 1112, 1113: propan-2-ol, butan-1-ol, ethane-1,2-diol.
- SNITREN™ grades 3110, 4110: produced on the basis of low molecular weight alcohols. The active substance content in the commodity form of the product is from 25% to 45% (4110).
- SNITREN™ grade 5111: propan-2-ol, butan-1-ol.
Purpose
The product is designed for use in oil production industry:
- SNITREN™ grades 1110, 1111, 1112, 1113: to facilitate transportation, pumping oil by reducing the hydraulic resistance of the flow of the pumped liquid in transporting oil pipelines.
- SNITREN™ grade 3110: for transport and pumping oil in accordance with GOST R 51858.
- SNITREN™ grade 4110: for transport, pumping diesel fuel by reducing the hydraulic resistance of the flow of the pumped liquid in the pipelines.
- SNITREN™ grades 5110, 5111: for transport, pumping gas condensate by reducing the hydraulic resistance of the flow of the pumped liquid in the pipelines.
Features
- allows you to significantly reduce the pressure in the pipeline;
- increasing flow rate up to 70%;
- reduces investment in the construction of loopings and additional pumping stations;
- reduces energy consumption for pumping;
- reduces the risk of emergencies;
- does not change the physical and chemical characteristics of hydrocarbons, does not affect the quality;
- not adsorbed on the surface of pipelines;
- does not have an impact on preparation of oil emulsions;
- can be used together with oil-field chemials.

DRA
DRA is dosed by special automatic dosing stations, that were built by MIRRICO Group and meet all requirements of the Customer.
Constant dosing into pipelines (oil pipelines, condensate pipelines) is recommended, the optimum dose is determined based on the results of pilot tests on site.
