Spinning band column
WebMar 13, 2024 · Modifications from the classical batch spinning band column extending the operating window and making the column more flexible are described. Particularly the variation of the slope of the spinning band as well as a flexible feeding system are investigated, where the height of the feeding position can be adjusted within the column. WebAug 28, 1981 · The optimum take-oft' rate for acetonitrile recovery was found to be 120-140 ml/h. Column hold-up was estimated to be 1.2 ml. Fig. 1 shows that the maximum sensitivity fluorescence spectrum of recovered acetonitrile to be virtually identical to that of unused HPLC grade acetonitrile.

WebElectrospinning is a voltage-driven, fabrication process governed by a specific electrohydrodynamic phenomenon where small fibers are yielded from a polymer solution. The most basic setup for this technique involves … Web2.2 Spinning-Band Columns From the 1930s on, SBCs varied a lot with their designs and material of the internals. Beginning with rotating metal parts attached to a metal shaft, Lesesne and Lochte [19] first pub-lished this idea of rotating internals instead of the packed or tray columns. Furthermore, Baker et al. [20] described the
Spinning band distillation is a technique used to separate liquid mixtures which are similar in boiling points. When liquids with similar boiling points are distilled, the vapors are mixtures, and not pure compounds. Fractionating columns help separate the mixture by allowing the mixed vapors to cool, condense, and … See more Spinning band distillation may sometimes be used to recycle waste solvents which contain different solvents, and other chemical compounds.

WebFurthermore, the spinning band column with its low pressure drop is well suited for vacuum distillation, opening a new operation window and application field. Hence, the implementation of a vacuum unit is targeted. Besides this, the geometry and design of the spinning band is further investigated, such as the angle of the spiral and a flexible ... WebA fractionating column is described together with its ancillary equipment for operation at high vacuum (0·01–2·5 mm. of mercury). At atmospheric pressure the column is equivalent to 16-6 theoretical plates, and under vacuum conditions at a boil-up rate of it operates with a total pressure drop of only 0·04 mm.
