Production Development of Modified Pulp for Oil Absorption (English)
Abstract [sv]

Detta examensarbete har skrivits i samarbete med Nordic Bioengineering med målet att effektivisera torksteget och kompressionssteget för deras hydrofobiskt modifierade pappersmassa. Länge har det funnits ett problem med rening av olja från oljespill och trots att mängden spill har minskat under de sista 30 åren, sker det än idag stora utsläpp som spillet från Deepwater Horizon och Sanchi. Genom denna produkt är det fullt möjligt att absorbera oljan i massan utan att den mättas med vatten. Med hjälp av ett torkskåp och en papperarksformare gick det att laborativt ta reda på hur absorptionsförmågan påverkas av olika torkningstemperaturer och av arkformning. Resultatet visar att det går att torka materialet till 170°C utan några större materialförluster, och att den packade massan får både en högre oljeabsorption och en högre vattenabsorption jämfört med den obehandlade massan.

Abstract [en]

This bachelor thesis has been performed in cooperation with Nordic BioEngineering and involved improving the drying step and packaging step for their hydrophobically modified pulp. Oilspill purification has been a problem for a long time and even though the quantity of oil spills has decreased during the last 30 years, are large oilspills still frequently occurring today with examples such as Deepwater Horizon and Sanchi. It is however fully possible, through this product, to absorb the oil in the pulp without saturating it with water. With help from a drying cabinet and a sheet former, it was made possible to find out by labwork if the absorbency was affected by different drying temperatures and by sheet forming. The results shows that the modified pulp can be dried at temperatures up to 170°C without greater material losses, and that the packed pulp has an increase in both oil absorption and water absorption compared to the regular pulp.
