New regulations on sulphur content in marine fuels : What will the consequences for the sulphur market and for the environment be with increased desuplhurisation in the oil refinerys? (English)
Abstract [sv]

Detta arbete uppkom på grund av de nya utsläppsreglerna för svavel som IMO antog år 2008. Dessa innebar att fartygen i framtiden behövde köra på bränslen med lägre svavelhalt. Ett av alternativen som var aktuella då var att avsvavla produkterna mer i raffinaderierna. Syftet med denna litteraturstudie var att ta reda på vad som gjordes med svavlet efter raffinaderierna, hur de nya reglerna påverkade svavelmarknaden och vad det skulle få för miljökonsekvenser att utvinna mer. Studien visade att svavlet användes inom många olika områden och var en viktig produkt. Efterfrågan och tillverkning varierade, men det fanns relativt stora lager på vissa ställen och det visades att dessa skulle komma att bli större på grund av ökad avsvavling i framtiden. Ökad avsvavling gav vissa miljökonsekvenser. Avsvavlingen i sig ledde till ökade utsläpp av växthusgaser. Även lagring i elementär form utomhus var något icke önskvärt ur miljösynpunkt. Dock fanns det alternativa lagringsformer som gav mindre besvär samt att det ständigt utvecklades nya användningsområden för svavel. 

Abstract [en]

This paper emerged because of the new emission rules for sulphur that were adopted by IMO in year 2008. This meant that the vessels in the future were required to run on fuels with lower sulphur content. One of the options was to desulphur the products more in the refineries. The purpose of this study was to find out what was done with the sulphur after the refineries, what it is used for, how the new regulations affected the sulphur market and what impacts it would have to the environment to extract more sulphur. It could be seen from the study that sulphur was used in many different areas and was an important product. Demand and production varied, but there were relatively large stocks at some locations, and it showed that these would become larger because of increased desulphurization in the future. Increased desulfurization gave some environmental consequences. The desulphurization itself led to increased emission of greenhouse gases. Also piles of sulfur were not something desirable from an environmental perspective. However, there were alternatives for storage that gave fewer problems and new uses for sulphur were under constant development.
