PRIMARY OIL REFINING AND HEAT EXCHANGER APPARATUS

Different technological processes are applied in the field of modern oil refining. Each of the processes in turn is implemented by many technological schemes and methods. In petroleum refining and chemical production, these technological processes provide the basis for many simple processes. In this way, the learning of the processes is facilitated. They process oil and its products by applying various processes. Oil refining and its main organic synthesis plants are composed of a collection of various technological processes and general plant farms. Depending on the number and quality of the products received from the factories, great attention is paid to the supply of hardware and equipment. It is through these equipment and devices that technological processes are carried out. Heat exchangers are among the most commonly used devices in the oil refining industry. The most common type of heat exchangers are shell-and-tube heat exchangers. Shell and tube heat exchangers are technological in the oil and gas industry pretreatment to improve properties and reduce viscosity of streams stages are widely used. Distribution of shell-and-tube heat exchanger design reliability and due to the variety of types and versions to work in a wide range of temperature, pressure and corrosive environment. At the current stage of production development, an important trend is increasing the efficiency of the used technological equipment, ensuring high energy efficiency in relation to heat exchange equipment. Flat cross-sections of different configurations are used to organize the cross current in the inter-tube space of the heat exchanger and to increase the cooling speed. The presence of such partitions significantly complicates the flow pattern of the cooling liquid, and is reliable for the flow around the tube bundle. Currently used methods of heat exchanger heat calculation based on criterion dependencies do not take into account all characteristics of the flow.
