Reagent of Complex Action for Oil Transportation

Abstract

Traditional methods of pipeline cleaning: scraping and heating of problem areas are quite timeconsuming and costly. Cost optimization in this area should be associated with the introduction of new high-tech technologies, as well as the use of effective domestic analogues of materials and components. Recently, the use of chemical reagents has become a method of influencing the rheological properties of the oil stream. It was found that solutions of the additive in toluene have optimal low temperature properties, which is obviously determined by its pour point (-95°C). The study of rheological properties was carried out at a low shear rate of 3.75 s-1, which corresponds to the starting loads on pumps of the oil pumping station, as well as in the range of shear rates at temperatures typical for gathering, infield and main oil transportation processes. Innovative methods for dealing with complications in oil transportation. Proposed by a number of developers, they are based on electromagnetic and ultrasonic treatment of the oil flow by stationary devices. Studies of dynamic viscosity during cooling in the temperature range from 70°C to minus 10°C made it possible to determine the depression of the saturation temperature of oil with paraffins in the presence of the developed reagent, which was 6°C, which reduces the cost of heating the oil-gathering header and infield pipeline when transporting oil in winter. At a low speed in the studied temperature range, the viscosity decreases by an average of 35%, which significantly reduces the starting loads on the pumps. This reagent may vary depending on the application conditions and reach 50% by weight. while maintaining the possibility of up to -30°C without preheating. The results show that the developed reagent effectively inhibits the formation of ASF in oils at economically reasonable concentrations of 100...200 g/m3 and is not inferior in efficiency to modern domestic and foreign analogues. On average, the intensity of the cleaning of pipes from the formed deposits will be reduced by 2.5 times.
