    摘要: Disclosed in the present invention is a polyether polyol refining method, comprising (1) neutralising or diluting crude polyether polyol to obtain a mixed solution; (2) flowing the mixed solution through a hydrophilic medium to aggregate same into a first density phase liquid and a second density phase liquid, the first density phase liquid being an aqueous solution containing alkaline metal ions and/or alkaline earth metal ions, and the second density phase liquid being polyether polyol; and (3) allowing the first density phase liquid to settle and separating same from the second density phase liquid to obtain refined polyether polyol. In the present refining method, using the hydrophilic medium for one-step removal of the alkaline ions and water in the polyether polyol simplifies the treatment steps, increases treatment efficiency, and can prevent polyether polyol loss; the obtained polyether polyol has low alkaline ion content and little odour. Also disclosed in the present invention is a polyether polyol refining apparatus, comprising a mixing unit and a separating unit, and being capable of refining polyether polyol with low alkaline ion content and little odour.

    摘要: The present disclosure relates to the design of structural features that enable the facile and reproducible fabrication of a microfluidic reactor that eliminates the problem of scaling factors in turn enabling the broad integration of microchannel reactors to industrial scale production. The process is highlighted via the effective and successful scale up of a purification process for the removal of a variety of different classes of impurities from crude vegetable oils mixtures into feedstocks that can be directly integrated into the hydrotreatment vegetable oil hydrogenation process for mass production of synthetic diesel derived from renewable sources.

    摘要: Processes are provided which utilize fiber conduit reactors/contactors to effect extraction from a fluid stream, particularly a fermentation broth, a waste stream of a fermentation process, a fluid comprising a dye, or a fluid comprising a pharmaceutical compound. In particular, methods are provided which include introducing a first stream comprising an extractant and a second stream which is substantially immiscible with the first stream into a conduit reactor proximate a plurality of fibers. The streams are introduced into the conduit reactor such that they are in contact with each other and the extractant of the first stream interacts with the second stream to extract a fermentation product, a fermentation byproduct, a dye or a pharmaceutical compound from the second stream into the first stream. The method further includes receiving the first and second streams in collection vessel/s and withdrawing separately the first and second streams from collection vessel/s.

Means are provided for introducing into an extraction chamber, the solvent, the mother liquor and a carrier gas. Such means simultaneously serve to atomize the solvent and the mother liquor and disperse same in the carrier gas whereby upon introduction a cloud phase is produced in the chamber.The introducing and simultaneously atomizing is carried out through one and the same spray nozzle. Condensation means are arranged in the extraction chamber and function to terminate the cloud phase and produce a condensed extracted mother liquor phase and a condensed solvent phase containing the substance to be extracted. Means are provided for separating the condensed extracted mother liquor phase from the condensed solvent phase on the basis of the different specific gravities of same.
