Another membrane/mesh microcontactor is applied for stripping of volatile components from organic liquid solutions [60]. Membrane openings were manufactured by laser micromachining or photochemical etching. The maximum pore sizes were between 10 and 100 μm, and the open areas were in the range 8–30%. A photo of assembled device is shown in Figure 9.8.

A polyacrylate mesh microreactor was also used for analysis of residence time distribution and phase holdup [61, 62]. Existence of hysteresis due to wetting characteristic of the mesh is observed and the liquid operating range was limited by the area of individual mesh types [61]. Uniform flow and residence time distributions are achievable through an analytical resistance network model [62].
