Membrane separation operations are still seldom used in refining today. The potential applications of the different ultrafiltration, pervaporation and gaseous permeation technologies are described in the other section. Since selectiv­ity is kinetic, a membrane separation module separates a mixture into prod­ucts whose composition may be very far from thermodynamic equilibrium. Provided the membrane is sufficiently …

Membrane Separation

Separation can also be based on kinetic selectivity, i.e. on a difference in migration velocity of the relevant components. This principle is used in a membrane separation operation as represented schematically in Figure 1.5 for a binary mixture of two components A and B. Separation is based on the difference in diffusion velocity of components …
