The supply of heat to oil media pumped by pipeline transport systems is one of the main problems in the oil industry. The article describes a method for supplying heat to oil-containing media using the energy of an electromagnetic field. The possibility of releasing surfaces in contact with oil sludge under the influence of electromagnetic fields has been shown by experiment. We describe the design and parameters of a biconical horn radiator of a microwave electromagnetic field operating at a frequency of 2 450 MHz. A method for generating energy and transmitting it to the emitter by means of a coaxial cable is shown. Testing the emitter in oil placed in an optically transparent and radio-tight double-walled tank is presented. The design of the stand allows us to safely examine the thermal process using a thermal imager. The installation made it possible to heat 7 liters of oil at 15 °C in 12 minutes.

Co2 Transport

Abstract Carbon dioxide transport from capture to utilization or storage locations plays key functions in carbon capture and storage systems. In this study a comprehensive overview and technical guidelines are provided for CO2 pipeline transport systems. Design specifications, construction procedures, cost, safety regulations, environmental and risk aspects are presented and discussed. Furthermore, challenges and future research directions associated with CO2 transport are sorted out including the large capital and operational costs, integrity, flow assurance, and safety issues. A holistic assessment of the impurities' impacts on corrosion rate and phase change of the transported stream is required to improve pipeline integrity. The influence of impurities and the changes in elevation on the pressure drop along the pipeline need to be further investigated to ensure continuous flow via accurate positioning of pumping stations. Although the long-experience in oil and gas pipeline industry forms powerful reference, it is necessary to develop particular standards and techno-economic frameworks to mitigate the barriers facing CO2 transport systems. Digital twins (DT) have potential to transform CO2 transport sector to achieve high reliability, availability and maintainability at lower cost. Herein, an integrated 5-component robust DT framework is proposed for CO2 pipeline transport systems and the future directions for DT development are insinuated. Data-driven-algorithms capable of predicting system's dynamic behavior still need to be developed. The data-driven approach alone is not sufficient and low-order physics based models should operate in tandem with the updated system parameters to allow interpretation and result's enhancing. Discrepancies between dynamic-system-models, anomaly-detection and deep-learning require in-depth localized off-line simulations.

Linear Elements

It is shown that the set of all linear elements of the system can be divided into 5 subsets G1...G5, depending on which specific nodes a particular pipeline connects. It was established that the greatest influence on the growth of resistance index values is exerted by the effect of an increase in the quantitative composition of the subset G1, and the smallest one is the increase in the composition of the subset G5. In this case, the degree of influence decreases with the transition from the elements of the subset G1 to G5. During repair operations, individual fragments or pipelines are usually excluded from the current system. Such structural applications can lead to a situation where accidental damage to several or even one pipeline will lead to disconnection of some consumers from the source. The specified feature should be taken into account when planning, preparing and conducting repair work. The existence of rational and irrational network structures, characterized by the greatest and least resistance to progressive damage, is proved. The planning and organization of repair work of pipeline transport systems is recommended to be carried out with a preliminary assessment of their resistance to progressive damage and taking into account the possibility of using rational network structures.

The paper outlines the scientific fundamentals for creating and applying the knowledge bases and the data banks in the design, construction and operation of pipeline transport systems. The analysis of knowledge is carried out, the main directions of knowledge base creation and its fundamentals are considered in terms of the pipeline transport of oil and petroleum products. The knowledge bases include both the existing system of scientifically validated proposals to the structure, classification, criteria, constitutive equations for design-and-experimental assessment of strength, stability, stiffness of the load-bearing elements of pipeline transport facilities, and further development of these proposals in terms of analyzing the operation life, reliability, and damage tolerance of the pipeline transport system, analysis of its protection against crisis and emergency situations. Data banks are considered as the initial information basis for the knowledge implementation at all stages of the pipeline transport system life cycle. It is concluded that the creation of the unified system of knowledge base and data banks is of significant scientific and practical importance for the further development of pipeline transport systems with regard to up-to-date requirements for ensuring and improving their strength, service life, reliability, damage tolerance, and safety of construction and operation.

Product Pipeline

Modern pipeline systems, both main and industrial, allow transporting a wide range of liquid and gaseous substances, including a variety of solid bulk materials, minerals, building materials and mixtures. However, the development of pipeline transport systems today is hindered by the lack of theoretical developments in the implementation of practical engineering projects for the creation of both main and industrial product pipelines for various purposes. Therefore, the further development of the theory of flows of various substances in pipelines and the creation of universal methods for engineering calculations of design parameters of pipeline systems based on this theory are priority tasks for the further development of product pipeline transport. The studies were carried out in accordance with the condition of stochastic transformation of the coagulation-thixotropic structure of the gel flow into sol. Such a stochastic transformation of the coagulation-thixotropic structure can be observed both when reaching the mode that determines the turbulent motion of a viscous colloidal solution, and somewhat earlier – at the stages of the laminar flow regime of the solution. Based on the formal phenomenological analysis, it has been determined that during the transition of the laminar mode of motion of the Newton fluid flow in a cylindrical tube to the turbulent mode, the transported structured gel flow is guaranteed to collapse into a colloidal sol. Based on the example of a typical design calculation of a technological (production) pipeline for the transportation of motor oils of the SAE-10 and SAE-40 grades, the optimal conditional internal diameters of the product pipeline were determined. The compliance of the design structural parameters of the pipelines with the corresponding physical and mechanical properties of the transported liquids was established. The proposed methods of engineering calculations of design parameters for technical objects of pipeline transport should expand and supplement the regulatory documentation for the preparation of projects for the construction of both main product pipelines and technological “interoperable” production pipelines
