21. Models for Wet Scrubbing of SO2 and NOx
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
22. A Model Based Approach to Robustness Analysis and Optimisation of Chromatography Processes
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
23. Simulation of Phosphorus, Zinc and Cadmium Mass Flow in Dairy Farming Systems
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
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
25. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose
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
