Study of the Effect of Physi̇co-Chemi̇cal Properti̇es on the Rheologi̇cal Properti̇es of Hi̇gh-Paraffi̇n Oi̇ls

For the first time, the joint effect of magnetic field, Difron-4201 depressor additive, new composition with conventional name N-1 and N-1 + magnetic field on paraffin deposition and freezing temperature in high-paraffin oil was studied. Laboratory experiments on paraffin deposition were performed by the “cold tube” method and the surface temperature of the tube was 5, 10, 15, 20, and 25 °C. The greatest decrease in the amount of paraffin deposits at different temperatures was caused by the influence of the combined method. The physical, chemical and physico-chemical effect on the freezing temperature of high-paraffin oil was carried out according to a known standard method. At this time, 600 g/t of Difron-4201 depressant additive and 500 g/t of N-1 composition were considered as the optimal usage rate. As in paraffin precipitation, the most effective influence on freezing temperature was with the presence of N-1 + magnetic field composition. It was also determined that the effect of magnetic field, Difron-4201 depressor additive, new composition with conventional name N-1 and N-1 + magnetic field on the effective viscosity of high-paraffin oil was obtained by the combined method. In order to study the bactericidal property, the effect of the new composition N-1 on the development of sulfate-reducing bacteria was also studied in laboratory conditions in Postgate-B nutrient medium for fifteen days, and its bactericidal effect was calculated. It was found that composition N-1 shows the highest bactericidal effect at a concentration of 500 g/t, and at this time the value of S is 97 %. Thus, it is possible to carry out pipeline transportation of highly paraffinic oils in cold climates without heating by using electricity at intermediate stations. This, in turn, provides energy savings. On the other hand, environmental protection is ensured by reducing the corrosion rate to a minimum, increasing the service life of pipelines and eliminating possible hydrocarbon losses. The possibility of reducing paraffin deposits by using the developed combined method can be applied when application fuel oil in heat and power generation. Bibl. 25, Fig. 3, Tab. 5.
