6. Västsvensk petroleumindustri 1945-2000 : etablering och tillväxt
Sammanfattning : The purpose of the study has been to describe and analyse the establishment and growth of the petroleum industry in western Sweden during the second half of the twentieth century. Empirical data shows that the development of refineries has in large part been governed by environmental changes where belonging to an international concern with large financial resources, and a determined investment in FoU in order to be at the forefront, has been advantageous.

7. Biological Treatment of Oily Sludge and Sediments
Sammanfattning : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. LÄS MER
8. Chemical-Looping Combustion with Solid Fuels
Sammanfattning : In order to meet the global demand of CO2 neutral energy production, chemical-looping combustion could play an important role. With this technique it is possible to capture CO2 without an excessive energy penalty. LÄS MER
9. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling
Sammanfattning : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. LÄS MER
10. Enhancement and Characterization of Films for Barrier and Release Applications
Sammanfattning : Films and coatings can improve the quality and shelf-life of food products by acting as barriers to e.g. water vapour and oxygen. Many edible biopolymer films, based on polysaccharides and proteins, form excellent oxygen barriers but most often provide only poor water vapour barriers. LÄS MER
