  1. 1. Reducing cadmium emissions to water during removal of electrostatic precipitator ash : Investigating the effect of process parameters on the formation and precipitation of insoluble cadmium salts in water solutions

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Lukas Esperi; [2022]
    Keywords : cadmium; electrostatic precipitator ash; heavy metals; hydroxide precipitation; recovery boiler; elfilteraska; hydroxidfällning; kadmium; sodapanna; tungmetaller;

    Abstract : The removal of electrostatic precipitator (ESP) ash by solving the ash in water constitutes an environmental problem if heavy metals, such as cadmium, present in the ash remain in the outgoing effluent streams. The ESP ash solution is alkaline, meaning cadmium is present as the insoluble salt Cd(OH)2, cadmium hydroxide. READ MORE

  3. 2. Optimering av kalkcykeln på Iggesunds bruk med avseende på specifik energianvändning

    University essay from SLU/Dept. of Energy and Technology

    Author : David Olsson; [2020]
    Keywords : energieffektivisering; mesaugn; elfilterstoft; sulfatmassa; kartongbruk;

    Abstract : Iggesund Mill is an integrated pulp and paperboard mill that makes kraft pulp and solid bleached board. In the pulp process, white liquor is used to make pulp. The white liquor is recovered in the recovery process. READ MORE

  4. 3. Raising the efficiency of black liquor lignin extraction

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Konrad Nilsson; [2017]
    Keywords : Chemical Engineering; Kemiteknik; Lignin; Black Liquor; Technology and Engineering;

    Abstract : The aim of this report was to study possibilities of making the process of extracting lignin from black liquor at pulp and paper mills more efficient in the form of a literature study. Lignin is a commodity that is likely to become more valuable in the future due to work being done by a number of companies in utilizing it as for example a base for the production of renewable fuels and carbon fibre.

  5. 4. Development of Wet Electrostatic Precipitator for Generation of Nanoparticle-Protein Solution

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Julia Adner; [2015]
    Keywords : WESP; Nanoparticle; bioligical identity; protein solution; Technology and Engineering;

    Abstract : To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. READ MORE

  6. 5. Modelling and Simulation of Electrostatic Precipitators with a Dust Layer

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Yevhen Ivanenko; [2015]
    Keywords : electrostatic precipitator; ESP; precipitation process; dust layer; resistivity of the dust layer; COMSOL Multiphysics;

    Abstract : A dust layer, especially based on high-resistivity dust, at the collecting electrodes may cause a back corona discharge in electrostatic precipitators (ESP). It can significantly reduce the ESP efficiency and as a result cause ecological damages. READ MORE
