  1. 11. Displacement Washing in the Sulfate Pulp Mill

    Författare :Gunnar Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal ions; Kraft pulp; models; diffusion; filter cakes; sorption; temperature; lignin; fibers; washing; lime mud; chemical recovery; displacement; pulp washing;

    Sammanfattning : Displacement washing is an operation in which it is possible to wash solid-phase particles with a minimum of water. In a sulfate pulp mill, the main application is the pulp washing, but lime mud washing also occurs in the chemical recovery. The washing consumes a great deal of water. LÄS MER

    Sammanfattning : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. LÄS MER

  5. 15. A geophysical investigation of carbonate build-ups in the Baltic Basin using reflection seismic and well data

    Författare :Tegan Levendal; Christopher Juhlin; Lars Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reflection seismic; Ordovician; Silurian; Carbonate mud mounds; Reefs; Gotland; Sweden; CAES; Seismic interpretation; OPAB dataset; 3D seismic; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : During the Late Ordovician, the region around Gotland was part of a shallow epicratonic basin in the southern subtropics. Low latitudes, relatively warm sea temperatures and the presence of a shallow marine environment promoted algae to flourish and diverse carbonate build-ups such as carbonate mounds and reefs developed on the southern margin of Baltica.
