Development of a system for automated control of oil transportation in the Arctic region to prevent the formation of paraffin deposits in pipelines

Abstract

The paper introduces a unique methodology of preventing and controlling the formation of paraffin deposits in oil pipelines, which is a matter of urgency in regions with negative temperatures, including the Arctic regions. The paper presents the configuration and specific parameters of the developed measuring unit. The proposed measuring unit is capable of detecting the formation of a paraffin layer during its early stages and predicting its composition. Simultaneous use of two radioisotope sensors allows increasing the performance capabilities of the measuring unit, namely to detect the formation of a paraffin layer in the early stages and to issue a signal to amplify the control signal to control the oil pipeline paraffinisation. In addition, the use of a radioisotope unit instead of a single sensor will increase the accuracy of component-wise flow rate measurement, by making an allowance for paraffin deposits formation. The use of customized information processing algorithms also allows determining oil viscosity with high accuracy. The paper deals with an optimization of a system for automated control of a promising method of electric heating via the skin-cables, wherein safety factors of up to 36% are currently used, i.e. in most cases, 1/3 excess electric power is generated. The safety of using the radioisotope measuring technique is proven.

Sustainability of Management Decisions in a Digital Logistics Network

“…Modern mathematical methods and approaches developed by the authors provide the necessary mathematical tools not only to describe the process on linear network fragments but to obtain adequate mathematical relationships describing the process at the junction nodes of linear network fragments. Additionally, the authors applied the integral functional of the quality of the logistics network [20][21][22][23][24]. The article investigates the boundaries of the stability of an evolutionary parabolic system and a differential-difference system with distributed parameters on a selected graph [25][26][27][28][29].…”

Development of methods for determining the relative weight of physical factors in pipeline paraffinization

“…The creation of this method would allow to determine the viscosity of oil stream using the same equipment that is already contained in the sensor for signaling on pipeline paraffinisation. Therefore, one of the stages of the study was the development of a method that meets the specific requirements, discussed in greater detail in [16].…”

World experience in the application of antitrust regulation and compliance system.

“…The Italian antitrust law does not contain rules that directly regulate exemption from liability or the application of extenuating circumstances in relation to violating companies as a result of the introduction of the antitrust compliance program. At the same time, the existence of an effective antitrust compliance system in an organization can be considered by the leadership on determining the number of fines for violations of antitrust laws as an environment that mitigates the responsibility of the violating organization (Feofanovich, 2019;Kopteva et al, 2019;Tarman, 2018;Prodanova et al, 2018a, b;Dyussembekova et al, 2019). In this case, the reduction in the amount of the fine can reach 15%, but taking into account the fact that the application of all extenuating circumstances will not result in a decrease in the fine of more than 50% (Guidelines on the calculation fines for serious).…”
