Modeling of the Flotation Process in an Industrial Apparatus

A relation for the effective mixing coefficient is obtained, which allows taking into account the scale effect when modeling mass-transfer processes in large-diameter devices within the framework of a one-dimensional diffusion model. The ratio explicitly takes into account the dependence of the value of the specified coefficient on the transverse unevenness of the hydrodynamic and concentration fields. Using the specified ratio, the process of flotation purification of industrial wastewater from oil-containing compounds was simulated. Comparison of the calculation results with the performance indicators of the flotation units at the Kirishi oil refinery proved the adequacy of the proposed model representations to the real industrial process.
