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
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : 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. LÄS MER
2. Optimering av kalkcykeln på Iggesunds bruk med avseende på specifik energianvändning
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and TechnologySammanfattning : 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. LÄS MER
3. Rökgasrening för småskalig avfallsförbränning i länder under utveckling : En kartläggning över föroreningar i rökgaser, deras uppkomst och hur de kan reduceras
Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Företaget Againity AB har planer på att driftsätta avfallsförbränningsanläggningar i områden av världen där avfallsförbränning inte är särskilt vanlig. Againity står därför inför utmaningen att rena rökgaserna till godkända nivåer. LÄS MER
4. Raising the efficiency of black liquor lignin extraction
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : 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. Development of Wet Electrostatic Precipitator for Generation of Nanoparticle-Protein Solution
Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologiSammanfattning : 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. LÄS MER
