Static membrane emulsification

The membrane emulsification can be considered as a case of microdevice emulsification process [17, 18] in which the porous membrane is used as microdevices. Membrane emulsification carried out in quiescent conditions is also referred to as static membrane emulsification, while membrane emulsification carried our in moving conditions (either the membrane, i.e., rotating module, or the phase, i.e., crossflow) is also referred to as dynamic membrane emulsification (Figure 21.2(b)). [Pg.466]

A number of approaches have been proposed for a continuous emulsification and improved control of product size distribution static mixers, membrane emulsification, and microchannel emulsification. For the last two, emulsions are produced by extruding a liquid through many individual pores or microchannels. [Pg.656]

As stated above, the focus of recent investigations of microreactor applications in the field of emulsification was on the use of micromixers, and different types of micromixers have been employed. However, it is difficult to compare them with regard to liquid-liquid dispersion performance since the mixers are most often investigated for different specific applications. However, a suitable comparison is the basis for future targeted equipment selection. Furthermore, micrombcers are in competition with conventional and other innovative equipment such as static mixers, membranes and homogenizers. Therefore, benchmarking with such equipment is also required. [Pg.872]
