Intensification of the heat exchange process in technological equipment

The intensification of the heat exchange process plays a key role in modern industry. Efficient heat exchange reduces the consumption of fuel and electricity needed to maintain the specified technological modes. The faster the heat transfer is carried out, the less time and energy is spent on heating or cooling raw materials, products and equipment. More intensive heat exchange reduces the duration of individual stages of the technological cycle, allowing faster production and more production per unit time, in addition, uniform and rapid heat exchange minimizes the risks of product defects caused by uneven temperature distribution. In conditions of offshore hydrocarbon production, the processes of categorical modernization of existing equipment or the introduction of new ones are problematic due to the limited platform area, high density of installations, the complexity of transporting newly constructed elements, as well as their installation. It is possible to intensify the heat exchange process in equipment using elastic vibrations of sound waves, mechanical vibrations of an object, effects on the flow of electrically charged particles, an increase in the temperature difference of thermal carriers or a change in the geometric characteristics of the structural elements of heat exchange equipment. To determine the method of increasing heat transfer, it is necessary to take into account the purpose of the device, its design features, parameters of thermal media and other factors. When analyzing the methods of intensifying heat exchange pro-cesses in technological equipment, it was revealed that one of the simplest and most effective ways to increase heat transfer is annular profiling of the surfaces of the working elements of the equipment. The simulation of the heat exchange process using a smooth tube profile and a tube with annular profiling was performed in the environment of the Kompas Flow Vision software package. The technological parameters are set based on the analysis of the technological scheme of oil treatment in the fields of the Northern Caspian Sea. It is revealed that profiling of the working element leads to an increase in the coefficient of heat transfer to the wall. Optimal geometric characteristics of the tube have been determined.
