Finally, in chapter 6 the effects of several membrane parameters on membrane emulsification Membrane emulsification has received increasing attention over the last 10 years, with potential applications in many fields. In the membrane emulsification process, a liquid phase is pressed through the membrane pores to form droplets at the permeate side of a membrane; the droplets are then carried away by a continuous phase flowing along the membrane surface. First is the membrane pore activation since only a fraction of the membrane pores are active in the emulsification process. This fraction increases when the dispersed phase applied pressure increases from zero at no flow to ~50% or more depending on the surface porosity and system characteristics. 2013-09-30 · Droplet size obtained is calculated and experimented to be usually 2–10 times larger than membrane pore size. Pore size, inter-pores distance and surface hydrophobicity are important factors that greatly affect the emulsification success [8,9].

Membrane emulsification is a process of injecting a pure dispersed phase or pre-emulsion through a microporous membrane into the continuous phase. As a 3.1 Characterization of tubular ceramic membranes - pore diameter and morphology The morphology of tubular ceramic membranes, evaluated by SEM, can be seen in Figure 2 . It is observed that the membrane structure is characterized by irregularly distributed pores with a relatively complex shape.
Obviously, if more pores are active, then the mean distance between two growing drops on the membrane surface at any given time will be reduced and the possibility of neighbouring drops interacting will be increased. 2018-04-27
In the study of Yasuno and colleagues , in which actually no cross-flow was applied and spontaneous emulsification was allowed to take place, very low pore activation (0.3%–0.5%) was found, which could very well be caused by wettability changes that prevent inflow of the continuous phase into the membrane. Among other parameters, pore size of the membrane, pressure of the disperse phase, and adsorption kinetics of the emulsifier influence the results of emulsification. To study the influence of their morphology and operating temperature on the CO 2 separation, This model assumes that no pores exist in the membrane, that a partial degradation has taken place during the heating. This fact was corroborated by TGA analyses (see Apparent activation energy section). Monolayers of the coating materials of course do not influence the pore size as these are orders of magnitude smaller the than mean pore size; however, clogged and accumulated material impact the smaller pores.
