    Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER

  3. 2. Conditions for resource-efficient production of biofuels for transport in Sweden

    Författare :Carolina Ersson; Mats Eklund; Jonas Ammenberg; Mikael Lantz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Transportation has continued to increase worldwide and fossil-fuel dependency is strong which leads to a number of problems, e.g. increased emissions of green-house gases (GHG) and risks related to energy security. Biofuels have until now been one of the few renewable alternatives which have been able to replace fossil fuels on a large scale. LÄS MER

  4. 3. Microbiological analysis of municipal wastewater treating photobioreactors

    Författare :Ivo Krustok; Monica Odlare; Emma Nehrenheim; Jaak Truu; Raul Muñoz; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photobioreactors; wastewater treatment; microalgae; microbiology; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. LÄS MER
