  2. 1. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements

    Author : Charlotte Marchand; Hogland William; Hijri Mohamed; Bramryd Torleif; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Petroleum Hydrocarbon; Trace Elements; Gentle Soil Remediation Options; Polycyclic Aromatic Hydrocarbon; Respirometry; Ecopile; Bacteria; Fungi; Miljövetenskap; Environmental Science;

    Abstract : The rapid urbanization and industrialization has led to an increase of disposal petroleum hydrocarbons (PHC) and trace elements (TE) into the environment. These pollutants are considered as the most toxic contaminants in the world due to their persistence in the environment, and the long range of toxicological effects for living beings. READ MORE

  4. 2. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile

    Author : Jörgen Samuelsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; petroleum; vitrinite reflectance; thermal maturation; flexural rigidity; heat flow; suppression; thermal conductivity; North West Shelf; Alum Shale;

    Abstract : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny.

  5. 3. Arctic Offshore Hydrocarbon Resource Development : Past, Present and Vision of the Future

    Author : Maria Morgunova; Vladimir Kutcherov; Rurik Holmberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Arctic; oil and natural gas; resource development; investment trends; offshore technology; production volume; projection; historical framework; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Abstract : Energy issues have always been on the global economics and geopolitics agenda, even though energy sources have been changing over time.In recent years, the awareness of Arctic offshore oil and natural gas development has escalated, yielding economic opportunities and incurring risks.

  6. 4. Experimental investigation of hydrocarbon formation and transformation under Earth´s upper mantle conditions

    Author : Anton Kolesnikov; Vladimir Kutcherov; Bertil Sundqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; theory of deep abiotic petroleum origin; natural gas; hydrocarbons; methane; ethane; graphite; hydrogen; high pressure; high temperature; CONAC; BARS; diamond anvil cell; Raman; X-ray; gas chromatography; Engineering mechanics; Teknisk mekanik;

    Abstract : The theory of the abyssal abiotic petroleum origin considers oil and natural gas to begenerated in the Earth’s upper mantle. Hydrocarbons migrate further through the deep faults into the Earth’s crust, where they can form oil and gas deposits in any kind of rock in any kind of structural position. READ MORE

  7. 5. Biological Treatment of Oily Sludge and Sediments

    Author : Mait Kriipsalu; Chalmers tekniska högskola; []
    Keywords : bioremediation; refinery; aerobic biotreatment; flocculation-flotation unit FFU ; petroleum hydrocarbons; oily sludge; static biopile; PAHs; sediments;

    Abstract : 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. READ MORE
