  2. 1. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

    Author : Eva Ståhl Wernersson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

    Abstract : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. READ MORE

  5. 3. Optimization, scale up and simulation of tumbling mills

    Author : Ming-Wei Gao; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Grinding is a fundamental process in the mineral industries. Grinding mills are often very large machines. Their efficiency and energy consumption therefore are of major importance. Problems of large ball mills are discussed in this thesis. READ MORE

  6. 4. Fundamental Investigations of Supercritical Fluid Chromatography

    Author : Martin Enmark; Torgny Fornstedt; Arvind Rajendran; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supercritical Fluid Chromatography; SFC; Modeling; Adsorption Isotherms; Scale-up; Peak Distortion; Injection; Design of Experiments; Perturbation Peak Method; Elution by Characteristic Points Method; Method transfer; Kemi; Chemistry;

    Abstract : This thesis aims at a deeper understanding of Supercritical FluidChromatography (SFC). Although preparative SFC has started to replace Liquid Chromatography (LC) in the pharmaceutical industry - because of its advantages in speed and its less environmental impact - fundamental understanding is still lacking.
