  5. 3. Pulp washing - Determining local properties using a new measurement technique

    Author : Jenny Lindau; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local properties; displacement washing; washing; measurement technique; pulp washing;

    Abstract : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will save a substantial amount of energy, reduce costs by reducing the need for make-up chemicals and improve the bleaching process. There are many discrepancies in the literature, however, as to how different parameters influence washing efficiency. READ MORE

  6. 4. Pulp displacement washing - An investigation of the influence of fibre and bed properties using a novel measurment technique

    Author : Jenny Lindau; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; displacement washing; pulp properties.; measurement technique; compression; dispersion; fibre damage; local properties; kraft pulp;

    Abstract : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will increase energy efficiency, reduce costs by minimizing the need for make-up chemicals and improve the bleaching process. Research in this area has, however, been more or less neglected and in the existing literature there are many discrepancies as to how different parameters influence the washing process. READ MORE

  7. 5. Acoustical properties of earplugs

    Author : Per Hiselius; Teknisk akustik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; acoustic modelling; objective measurement; insertion loss; earplugs; HPE; HPD; hearing protectors; Two-Port; Four-Pole; attenuation; electro acoustics; acoustics;

    Abstract : In this study an experimental setup for measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is applied to earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent on duplicating the human ear. READ MORE
