Convective Mass Transfer in Composite Materials

In this section, mass transport across porous composite membranes and dense particulate-filled composite membranes (also called mixed matrix membranes) is considered with convection at the boundaries of the membrane. The systems are generally assumed to be dilute so that the mass transfer coefficients are the same for coordinate systems both stationary and moving at the average molar velocity. The cases considered are as follows: (1) separation of solute from one gas phase to another using porous membrane, (2) separation of solute from aqueous phase to organic phase using hydrophobic porous membrane, (3) separation of solute from aqueous phase to organic phase using hydrophilic porous membrane, (4) separation of solute from one bulk phase to another using dense mixed-matrix membrane.
