1. Off-gassing from thermally treated lignocellulosic biomass
Sammanfattning : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. LÄS MER
2. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes
Sammanfattning : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

3. Investigations on the Oxidation of Iron-chromium and Iron-vanadium Molten Alloys
Sammanfattning : With the progress of high alloy steelmaking processes, it is essential to minimize the loss of valuable metals, like chromium and vanadium during the decarburization process, from both economic as well as environmental view points. One unique technique to realize this aim, used in the present work, is the decarburization of high alloy steel grades using oxygen with CO2 in order to reduce the partial pressure of oxygen. LÄS MER
4. Characterization of oxy-fuel flames - their composition, temperature and radiation
Sammanfattning : Oxy-fuel combustion is receiving growing attention as one of the promising CO2 capture technologies in connection to power production. Yet, significant efforts are required in research and development of this combustion process in order to be able to design and optimize a full scale power plant. LÄS MER
5. Development and use of an optical pCO2 sensor in marine studies
Sammanfattning : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. LÄS MER
