1. On Degradation and Monitoring Tools for Gas and Steam Turbines
Sammanfattning : The revenue from a power plant is strongly dependent on the life cycle cost. Today, when the market conditions for power-producing companies have shifted from a protected market to a deregulated market, the need for tools to monitor power plants has increased significantly. LÄS MER
2. An Experimental and Theoretical Study of Decentralized Gas Fired Liquid Heating
Sammanfattning : The effects on the energy situation in industry when gas fired liquid heaters replace steam have been determined by energy surveys performed in a brewery and a slaughterhouse, measurements of the performance and emissions from liquid heaters installed in these industries, and theoretical analyses of the potential energy saving. The theoretical study in the first part of the project provides information that allows assessment of the effects on the energy situation, of part or complete conversion to decentralized heating, under the conditions prevailing in the industries concerned.

3. From Laboratory to System. Studies of Superheated Steam Drying of Biofuel
Sammanfattning : Replacement of fossil fuels by more sustainable fuels such as biofuels has become increasingly important during the last decade. This is mainly due to economical and environmental reasons. LÄS MER
4. Fuel Ethanol Production from Corn Stover: Optimization of Steam Pretreatment and Improvement of Simultaneous Saccharification and Fermentation
Sammanfattning : Fuel ethanol, produced from biomass, could well be tomorrow's replacement for gasoline. This thesis deals with the production of fuel ethanol from corn stover using an enzymatic process consisting of the following main steps: steam pretreatment of the raw material, enzymatic hydrolysis, fermentation of the sugars and ethanol refining.

5. Two-Stage Conversion of Land and Marine Biomass for Biogas and Biohydrogen Production
Sammanfattning : The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). LÄS MER
