Dissecting the Chain Length Effect on Separation of Alkane-in-Water Emulsions with Superwetting Microchannels

Abstract: Oil/water separation is an essential process in the petrochemical industry, environmental remediation, and water treatment. Alkanes are the major components of crude oil and are difficult to separate once they form emulsions in water. Much less attention has been focused on the feature of liquid alkanes that could, in turn, influence the separation process. The role of chain length is systematically studied herein by separating the alkane-in-water emulsions with superwetting titanium microchannels of 14−55 μm.… Show more

“…With the introduction of the superhydrophilic surface, the liquid can establish a more curved liquid meniscus during the spreading process, leading to improved Laplace pressure, which accelerates the spreading of the uid within the channel. 44,45 The spreading process of channels with varying depths is illustrated in Fig. S3 and S4.…”

“…In the case of low Reynolds numbers, fluid flow within a channel with stable boundary conditions could be accurately calculated using simulation software such as COMSOL software [19][20]. We selected two-phase flow, level set, laminar physics interfaces and utilized a two-dimensional axisymmetric dimension to establish a 2D modeling analysis.…”

“…In this study, TNTs with a high specific surface area were prepared on porous titanium by internal anodization, which is more suitable as a substrate than Ti foil. Porous titanium has a porous structure and higher specific surface area, and the solution can flow through the inside, thus greatly increasing the effective contact area. Then, TNTs were subjected to appropriate HT reaction, loading Na + at the top and retaining the tubular structure at the bottom to ensure adhesion.…”
