The paper presents the estimate of hydrodynamic parameters of the gas phase motion at low-temperature fractionation of boron trifluoride in a packed column. The following parameters are detected: density and viscosity for reacting phases in the operational temperature range, gas velocity at the phase inversion point, Reynolds number, and retention capacity for the investigated types of packed beds. Using the Logos software, numerical simulation of gas velocity and pressure distribution in the packed bed is performed for fractionation of boron trifluoride.
