Analysis of emulsions concentration changes during imbibition in porous sorbents
Shtyka, O. S.; Błaszczyk, M. M. & Sęk, J. P.
Abstract
The stabilized emulsions removal from the
aqueous systems is supposed to be an issue as important as
the free oil products recovery. This work was conducted to
investigate the mechanisms of oil-in-water emulsions
sorption in a non-woven oleophilic/hydrophobic material
forced by the capillary suction pressure, and the saturation
level of such material during this process. It ensures the
effective application of the sorbents and facilitates the
development of alternative high-performance sorptive
materials that can contribute to diminishing of the negative
consequences of the aquatic environment contamination.
The main aspect investigated in this research work was
kinetics of the imbibition process in the porous media to
define the optimal time of sorption and the height of the
emulsions penetration. The measurement of the dispersed
phase concentration changes with the increase in an
emulsion front in the porous medium using the nephelometrical
method is the advanced approach in the field of
assessment of sorbents efficiency. The tendency of the
imbibed emulsion concentration decrease versus the height
was observed, which depended strongly on the viscosity
and the initial composition of a penetrating liquid. The
observed process was described by the mathematical model
based on Hill equation.
