  1. 21. Models for Wet Scrubbing of SO2 and NOx

    Författare :Charlotte Brogren; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limestone scrubbing; wet scrubbing; absorption; WFGD; flue gases; SO2; mass transfer; NOx; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. LÄS MER

  2. 22. A Model Based Approach to Robustness Analysis and Optimisation of Chromatography Processes

    Författare :Niklas Jakobsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Langmuir; SMA; Optimisation; Robustness; Chromatography; Prepartive process scale; Modelling;

    Sammanfattning : One of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. LÄS MER

  3. 23. Simulation of Phosphorus, Zinc and Cadmium Mass Flow in Dairy Farming Systems

    Författare :Anna-Karin Modin Edman; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Miljöstudier; Environmental studies; management; Cd; Zn; P; mass balance; system analysis; simulation;

    Sammanfattning : A simulation model, FARMFLOW, was developed for the calculation of phosphorus (P), zinc (Zn) and cadmium (Cd) stocks, flows and balances in different parts of a dairy farming system. The simulated continuous change in element stocks within the farming system enables evaluation of the long-term effects of management practices. LÄS MER

  4. 24. Ethanol from Softwood - Techno-Economic Evaluation for Development of the Enzymatic Process

    Sammanfattning : Ethanol produced from renewable resources can be used to replace fossil fuels such as gasoline and diesel. This thesis deals with the development of the enzymatic process used for ethanol production from softwood. LÄS MER

  5. 25. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose

    Författare :Andreas Rudolf; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Fermentation; Lignocellulose; Hydrolysis; Bioethanol;

    Sammanfattning : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. LÄS MER
