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.

The analysis has been carried out and the laws of occurrence of emergency threats at pipeline transport facilities associated with the sequential damage of structural elements have been established. When an emergency situation develops, blocking of a separate system node is associated with simultaneous transition to a state of inoperability of all pipelines converging into the zone of that node. Such damage to the point element of the network structure prevents product flows from passing through that point. The ability of a system to withstand a progressive blocking depends on its composition, structure, and is characterized by an indicator of persistence, the value of which is calculated using a simulation method. An example of the use of cluster schemes in solving the problem of structural synthesis and the selection of the best protection option for a pipeline transport system has been considered.

The article deals with the problem of transportation of agricultural products. The main causes of problems in this area are identified. The mechanism of creating favorable conditions in the system of globalization relations of the modern economy is analyzed. The fundamental elements in the transport system are competition orientation and information ownership over a certain period of time. Globalization involves the integration of different types of transport systems at the sectoral characteristics. The purpose of the research is to study the essence, meaning and prospects of the concept of “economic transport space in the national food supply system" in the processes of food market globalization. The main indicators of the “economic space" are: first, to determine the parameters that characterize the economic transport space, and secondly, to determine the prospects for using its structural elements in the system of transport supply relations, depending on the temporal and spatial components in the modern sector of the economy to provide food for the needs of society.

Analysis of a computer simulated case study of the nonlinear thermoelastic behavior of the joint between the column and the knee in a milling machine is presented. Significance of this behavior on the thermal deformation of contacting structural elements is evaluated. Computer simulation is performed by applying the approach based on recognition of interactions taking place at the joint. Through successive iterations, a convergence to the state of equilibrium is reached. Convergence is verified on a simplified model. The results indicate the significance of considering the behavior of the joint in predicting the thermal deformation, as the effect of this behavior extends throughout the structural elements. For the case under study, deformation of the structure differs noticeably from that without considering interactions at the joint. Distribution of the contact pressure, thermal contact conductance and heat flux along the joint indicate high degree of nonuniformity, which is responsible for the effect the joint has on the thermal deformation. Convergence to the state of equilibrium is reached in an oscillatory manner, as shown by the deformation of the knee. The simulated case is treated under the steady state conditions, however the approach can be extended to the transient state as well.

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.
