“…The main difference between the previously studied azeotropic mixtures [1][2][3][4] and the current system (hydrogen-hydrocarbon mixture) is the product outlet stream. In the azeotropic mixture case, the alcohol (either ethanol or isopropanol) is the product.…”

“…As such, it is the hydrocarbon most difficult to separate from hydrogen using FricDiff. In contrast to earlier applications of FricDiff [1][2][3][4], the product of interest, hydrogen, diffuses faster than hydrocarbon molecules and is thus recovered with the mass separating agent.…”

“…The full model equations have been presented elsewhere [2]. When modeling a single FricDiff tube, the process is divided into three parts: feed side, sweep side and the barrier [2]. The transport of the molecules through the sweep side and the feed side is modeled assuming plug-flow and using the Hagen-Poiseuille equation.…”

Processes such as chromatographic separation and nanofiltration can remove low molecular weight sugars from liquid mixtures of oligosaccharides. As an alternative for the separation of such liquid mixtures, we studied mass diffusion separation of such sugars in a microfluidic device with incorporated nanofiltration membranes. This separation method is based on differences between diffusivities of components and does not require high transmembrane pressures. The effects of channel depth and flow rate were studied in experiments. The key parameters selectivity and rejection increased with increasing channel depth due to increased external mass transfer limitations. Among the studied membranes, the obtained selectivities and rejections correlated to the specified retention values by the manufacturers. Compared to more conventional nanofiltration where high pressure forces solutes through membranes, we obtained corresponding selectivities and fluxes of only an order of magnitude smaller. Simulated results indicated that with optimized microchannel and membrane dimensions, the presented separation process can compete with currently available separation technologies.
