Abstract
CRUDE OIL
 The article considers the possibility of changing the set of quality indicators that are currently used to determine the degree of readiness of crude oil (oil or gas condensate for the integrated relative dielectric constant) (ε), which characterizes the electrical properties of crude oil and refined products. Сontrol over the operation of crude oil treatment plants, which are of key importance in the chain of technological operations aimed at obtaining marketable petroleum products.
 It has been experimentally established that the increase in the value of (ε) is significantly influenced by the presence of formation water in the crude oil, with dissolved chloride salts and semiconductor mechanical impurities, represented by Fe2O3 particles - corrosion products of process equipment. Conversely, the presence of dielectric mechanical impurities in the crude oil (SiO2) reduces the value of the indicator (ε). This, in turn, must be taken into account when establishing the total impact of pollutants on the indicator (ε) of crude oil.
 The implementation of the proposed approach is based on the use of two-section capacitive sensors, which are installed on the pipeline with the main material flow of the installation - desalinated and dehydrated crude oil, using outlets and couplings.
 Based on laboratory studies using model media, a multiple linear regression equation was obtained, which, depending on the content of mineralized water and mechanical impurities (semiconductor and dielectric nature) in oil or gas condensate, calculates the value (ε) with the average slope at the level of 1.39% and 2.06%, respectively.
