… The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by …
Hållbara uppvärmningsalternativ för vandrarhemmet på Finnhamn
… systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler. Information for …
… that all the plantsare profitable if all the synergies are utilized and the oil price is above 120 $/fat. Therevenues from freshwater production and cooling greatly contribute to the profitability.
Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One …
… convection. An example of this can be seen when heating a pot of oil from below. A part of the contribution to the formation of these cells is attributed to the variation of surface tension due to heating. This contribution is of less signicance when the ?uid layer is thicker …

Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order …
Energi i form av olja möjliggjorde under 1950- talet en mekanisering av skogsbruket. Accelererande klimatförändringar ställer nu krav på att den fossila energin som skogsmaskinerna är beroende av måste ersättas. Syftet med uppsatsen är att utifrån ett kulturperspektiv undersöka …
… of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards …
Riskklassificeringssystem för VTEC
… in geological formations (CCS) use the technology as a mean to extract more oil and gas; which results in a rebound-effect. Therefore, carbon dioxide capture in geological formations is not a realistic method unless it can prevent further emissions. Protected forest resources …
