  1. 1. On the Influence of Mixing and Scaling-Up in Semi-Batch Reaction Crystallization

    Författare :Marika Torbacke; KTH; []
    Nyckelord :reaction crystallization; precipitation; benzoic acid; macromixing; mesomixing; micromixing; semi-batch; loop reactor; backmixing; colour experiments; scaling-up;

    Sammanfattning : Semi-batch crystallization experiments have been performedboth in a loop reactor and in stirred tank reactors.Hydrochloric acid was fed to a stirred solution of sodiumbenzoate, and benzoic acid immediately formed. Benzoic acid isformed in excess of the solubility making the solutionsupersaturated.The loop reactor is U-shaped. LÄS MER

  3. 2. Novel Microsystem Techniques for Liquid Manipulation and Pressure Sensing

    Författare :Jessica Melin; Göran Stemme; Sabeth Verpoorte; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; microsystem technology; pressure sensing; liquid manipulation; liquid control; micromixing; Mikrobiologi; Microbiology; Mikrobiologi;

    Sammanfattning : Scaling down operations and functions into the fascinating micro world not only improve performance, lower costs, and enable easier integration, but also opens the door to new functionalities. This truly multidisciplinary thesis presents novel solutions to current and relevant challenges in the areas of 1) on-chip liquid manipulation which has applications in micro total analysis systems, medical diagnostics, and drug discovery and 2) pressure sensing which has an established market in the automotive and industrial processes industry.

  4. 3. On the influence of micromixing in reaction crystallization

    Författare :Magnus Lindberg; KTH; []
    Nyckelord :;

    Sammanfattning : In crystallization, the mean crystal size is governed by thetotal number of crystals sharing the total mass produced in theprocess. In reaction crystallization, it is believed that asignificant part of the crystals is formed during the localcontacts between reactant solutions close to the feed point. LÄS MER
