【 摘 要 】

Development of resources of heavy hydrocarbons is possible due to the evolution of technologies of their processing, including through the intensification of technological methods implemented in the field of their production at oil treatment plants. The research is devoted to the creation of a method of refining heavy hydrocarbon raw materials based on multiple increases in the working surface of the liquid phase during its intensive evaporation. The intensification of the single evaporation process is based on the fact that the heated raw material is sprayed in a hollow apparatus with the division of the final product into a distillate and a bottomless residue. Due to the spraying of raw materials, the interface of the phases is greatly increased, the supramolecular convective mass transfer becomes so large that it is comparable to the diffusion transfer. The aim of the study is to obtain the data necessary to create energy-saving technologies for the separation of heavy hydrocarbon resources. The paper discusses the possibility of improving the process of single evaporation of heavy oil due to the development of the working surface of the liquid phase, which is realized by spraying the latter. The process of crushing oil into droplets is considered in unity and interrelation with all phenomena occurring in the apparatus. The phase boundary increases several times, which makes supramolecular convective mass transfer comparable to diffusive transfer, which allowed for the separation of heavy oil to increase the distillate selection more than 3 times, with the weighting of the residual product.
