Mechanisms for Direct Separation of Oil from Water with Hydrophobic Hollow Fiber Membrane Contactors

Oil–water separation in membranes traditionally involves the transfer of water through the membrane. Instead, this study presents the novel approach of permeating insoluble oil through a hydrophobic membrane while rejecting the water. Benefits of this oil–water separation method appear to include both efficient separation and creation of a high-quality oil permeate stream as well as reduced surface area requirements. In the membrane process, oil flux is controlled by both the coalescence of oil droplets on the membrane surface and the selective permeation of oil through the microporous membrane wall. These competing mechanisms were investigated over a range of key process parameters including influent oil concentration, flow rate, transmembrane pressure, and viscosity as well as key membrane properties including membrane surface area and fiber spacing. Ultimately, a deterministic model for the effective surface area was developed to aid in the preliminary design and operation of a microporous hydrophobic membrane contactor that recovers insoluble oil from oil–water mixtures.
