Liquefied natural gas (LNG) is of great importance in the energy segment of the economy. Natural gas, has a higher calorific value, better fuel efficiency and is more environmentally friendly, thereby gaining more importance compared to oil and coal. Not only does LNG offer greater flexibility in supply, it also has cost advantages for transportation starting from a distance of 2,000 km (at sea) and 4,000 km (on land) respectively. Consequently, the LNG market will grow in the coming decades compared to two other fossil sources - oil and coal. To use natural gas, it is necessary to create safe and economically profitable transportation routes from natural gas deposits to end users. One possibility is to transport gas in a liquefied state, at low temperatures. To ensure safe and reliable storage of liquefied gas at minus 163 ° C, good physical and mechanical properties of the base material and weld (corresponding tank system) are required. To meet these high requirements, appropriate welding methods and welding materials are selected. The paper presents an analysis of activities on the development of new welding materials and improvement of welding technologies for the construction of LNG tanks.

“…From the point of view of corrosion, the greatest risk of destruction of the tank is water (bottom, lower belts of the tank) and gas-air mixture (roof, upper belt) due to saturation with aggressive components: hydrogen sulfide, carbon dioxide, salts. According to statistics, the main reason for the withdrawal from the operating mode of oil tanks is the corrosive wear of the surface [1][2][3][4][5], which comes into contact with the aggressive medium.…”

Inner surface of tanks is subject to corrosion due to constant contact with aggressive medium. The greatest danger from the point of view of possible corrosion destruction of steel is water (bottom, lower belts of the tank) and gas-air mixture (roof, upper belt) due to saturation with aggressive components: hydrogen sulfide, carbon dioxide, salts. Failure statistics show that the main reason for the failure of oil tanks (about 70%) is the corrosive wear of the surface that comes into contact with the aggressive medium. The application of paint coatings on the internal surfaces of steel tanks for the storage of oil and oil products is an effective measure to reduce corrosion and increase the life of tanks. However, there are a great many coatings. From the experience of tank operation, paint coatings of the following types were selected to analyze the effectiveness of corrosion protection: XC-717, EP-0020, FL-777, VN-780. To select the paint coating of the inner surface of the tank, physical and mechanical parameters were determined and calculations of the corrosion rate of the tank walls for the above paint coatings were carried out. After physical and mechanical tests, it was established that the best values of the coating are EP-0020. Thus, it is recommended to use a EP-0020 coating as a passive protection of the inner surface to ensure the durability of the tanks.

“…Heat exchangers of technological installations significantly affect the efficiency and reliability of the installation as a whole. A decrease in the reliability of heat exchangers of technological installations (condensers, reboilers) can lead to a significant decrease in the efficiency of the installation [1][2][3][4][5][6][7]. Failures in the operation of heat exchangers almost always lead to a decrease in the technical and economic indicators of the installation.…”

In modern industry, specially designed devices, called heat exchangers, are used to carry out heat exchange between working bodies (heat exchangers). They are widely used in all industries (chemical, oil and gas, food, etc.), which is due to the high reliability of the design, high productivity, simplicity of design and a variety of types and designs. The objective of the investigation is to simulate heat exchange in a shell-and-tube heat exchanger without an annular gap between the housing and segment transverse partitions and with a gap equal to 6 mm, and then determine at which of these two gaps the heat exchanger thermal efficiency is highest. The simulation was performed in ANSYS Workbench. The comparison of the energy efficiency of the apparatus was made using the Kirpichev criterion. This criterion is quite simple and does not require finding a large number of various parameters. With this criterion, it is possible to determine in which case the heat exchanger will be most advantageous in terms of energy efficiency.
