“…Moreover, this method could be used to solve various petrochemical problems. For example, as shown recently, it is possible to separate sulfurcontaining components from oil [28] and aviation fuels [29]. At the same time, liquid-liquid membrane contactors can be applied to purify biodiesel fuel from unreacted components (rapeseed oil, methanol, glycerin) [30].…”

A promising solution for the implementation of extraction processes is liquid–liquid membrane contactors. The transfer of the target component from one immiscible liquid to another is carried out inside membrane pores. For the first time, highly asymmetric track-etched membranes made of polyethylene terephthalate (PET) of the same thickness but with different pore diameters (12.5–19 nm on one side and hundreds of nanometers on the other side) were studied in the liquid–liquid membrane contactor. For analysis of the liquid–liquid interface stability, two systems widely diverging in the interfacial tension value were used: water–pentanol and water–hexadecane. The interface stability was investigated depending on the following process parameters: the porous structure, the location of the asymmetric membrane in the contactor, the velocities of liquids, and the pressure drop between them. It was shown that the stability of the interface increases with decreasing pore size. Furthermore, it is preferable to supply the aqueous phase from the side of the asymmetric membrane with the larger pore size. The asymmetry of the porous structure of the membrane makes it possible to increase the range of pressure drop values between the phases by at least two times (from 5 to 10 kPa), which does not lead to mutual dispersion of the liquids. The liquid–liquid contactor based on the asymmetric track-etched membranes allows for the extraction of impurities from the organic phase into the aqueous phase by using a 1% solution of acetone in hexadecane as an example.

“…On the other hand, high ratio of surface area to volume provided by fibers is of great significance in separation processes 18 . Jet‐fuel desulfurization, 19 CO 2 removal from raw biogas, 20 natural gas sweetening, 21 and pharmaceutical removal from aqueous streams 22 are among several applications of HFMCs. In accordance with a research done by Williams et al, 22 immobilizing canola oil in hollow fiber membranes and its regeneration can continuously cause 4‐IBAP extraction from contaminated water passing through the shell side.…”

In this study, modeling and simulation of removing a common pharmaceutical contaminant by a hollow fiber membrane contactor (HFMC) were carried out. For this purpose, a model was presented for separation of ibuprofen from wastewater in the membrane contactor. The suggested model was developed by coupling the mass and momentum equations. The partial differential equations (PDEs) and the corresponding boundary conditions of the model were solved using the computational fluid dynamics (CFD) techniques. The results showed that the predictions of this model were in close agreement with experimental data obtained from the literature. Moreover, the effects of different design and operating parameters on the removal of ibuprofen were studied. The simulation results revealed that the removal of ibuprofen was increased by increasing the membrane porosity and the length of fibers. The ibuprofen removal efficiency was also enhanced up to 93.2 and 90.2% by increasing the inner radius and the number of fibers from 110 to 145 μm and 3,000 to 15,000, respectively. As a result, this study illustrates the successful development of the CFD model for prediction of ibuprofen removal using HFMC according to which removal efficiency of more than 95% was achieved.
