M. Šećerov Sokolović, Dunja S. Sokolović, Slobodan M. SokolovićThe liquid–liquid model dispersions encompassing
four mineral oils of different properties were separated using polyurethane
fibers. Experiments were carried out over a wide range of oil properties,
bed permeabilities, and fluid velocities. The objective was to introduce
multivariate analysis as a statistical method for the estimation of
the efficiency of separation of liquid–liquid dispersions by
flow through fiber beds. The bed coalescence efficiency was followed
by monitoring the changes of critical velocity. On the basis of the
principal component analysis, reduced dimensionality and a lower number
of variables, an improved statistical treatment of the measurement
data was performed. An empirical equation was derived describing the
critical velocity as a function of the oil viscosity, interfacial
tension, dielectric constant, emulsivity, and bed permeability.
