Abstract

Separation of liquid and solid particles from a gas stream is an integral part of many technological processes in chemical, food, petrochemical, microbiological, energy and other industries. Separationprocesses of gas-liquid streams are of great importance in mass transfer, evaporation, rectification, wet gas purification, field treatment of produced natural gas. In these processes the motion of particles in a continuous gas medium is the determining factor. In mass-exchange apparatuses inter-plate drift reduces the efficiency of mass transfer, and drift between apparatuses disrupts the operation of technological units as a whole. Separation devices are used at all stages of hydrocarbon production and processing. The separation process depends on many factors: the design of separation devices and their operation modes, the content of solid or liquid phases in the main flow and their disperce composition, physical properties of the separating phases, etc. Mathematical modeling of the movement of phases in the swirling flow taking into account the main factors allows a more accurate assessment of the efficiency of the separation process. Qualitatively performed separation allows to reduce operating costs and improves the quality of commercial products. In this paper, the forces acting on a spherical particle in a swirling gas flow are considered. A mathematical model of the separation process in gas-liquid streams is developed, which allows to determine the minimum size of captured droplets taking into account changes in design, technological and rheological parameters. The disperse composition of separating particles is determined by the experimental method and the distribution of their volumes is described. The degree of separation is estimated. The obtained results can be used in the design of separators.
