Numerical Simulation of the Centrifugal Separator for Oil-Water Emulsion

Abstract

Calculation of a centrifugal water oil separator is shown. The separator represents alternative method of purifying water of oil inclusions and sludge (at a concentration up to 12%). The problems of creating a computational mesh, defining boundary conditions, separation two phases of oil-water emulsion and efficiency of separation are considered.

Energy Performance of Particle Settling in Cyclones

“…Owing to the symmetry of vertical gas fluctuations, which take equal positive and negative values we assume that the ratio of the particles of each sort which have changed their velocity to the velocity of another sort to the mass of all the particles are equal: ω 11 = ω 22 =ω 12 = ω 21 = ω 0 . As it is shown in [4] ω 0 = ω L which can be calculated by (Eq.1). Now we consider the balance of the mass of the particles of the first sort.…”

“…These motions are considered to be independent from of each other therefore making it possible to use their superposition [9,13,22]. Normally the impact of the rotational flow turbulence is not taken into account in the existing models or it's considered within the frames of semi-empirical models of turbulent diffusion, in which turbulent diffusion factor is considered as a parameter which specifies the impact of the flow turbulence on addition dispersion [4,23,14]. There are no experimental data providing accurate value of this parameter in the scientific surveys.…”

Extraction of iron-containing catalyst from chlororganic wastes generated by ethylene chlorination

“…Centrifugation for the separation of water-oil emulsions and the processing of oil ash in industry is often carried out using equipment from ALFA LAVAL -decanter centrifuges (https://www.alfalaval.ua/products/separation/centrifugal-separators/decanters/). The study of emulsions under centrifugation is ongoing [28][29][30].…”
