  1. 31. Modelling of Kraft Cooking Kinetics Using Near Infrared Spectroscopy

    Författare :Niclas Andersson; []
    Nyckelord :;

    Sammanfattning : A kinetic model describing the kraft cooking degradation reactions for softwood lignin and carbohydrates was developed in this thesis. The model satisfactorily predicted the data for modified as well as conventional cooking schemes, something which eluded earlier published models. LÄS MER

  3. 32. Optimization methods for sedimentation and denitrification in activated sludge

    Författare :Serena K. R. Hasselblad; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; solids flux; wastewater treatment; secondary clarifier; activated sludge; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : Denitrification on readily biodegradable carbon compounds and separation of biological sludge from effluent water are examples of critical sub-processes for nitrogen removal in activated sludge. The aim of this thesis was to find operational strategies and newmethods to optimize these processes. LÄS MER

  4. 33. Development and use of an optical pCO2 sensor in marine studies

    Författare :Dariia Atamanchuk; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pCO2; O2; sensor; optode; cross-sensitivity; carbonate system of seawater; biogeochemistry; Redfield ratio; the Koljo Fjord; cabled observatory; CCS; QICS; environmental engineering; leakage detection; MVDA; DoE;

    Sammanfattning : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. LÄS MER

  5. 34. Evaluation of volatile organic compounds related to board based packaging by use of instrumental and sensory analysis

    Författare :Gunnar Forsgren; Fredrik Winquist; Ola Karlsson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The main topic of the thesis is characterisation and evaluation of volatile organic compounds emitted by packaging materials based on paperboard products. The properties and concentration of these compounds are critical to how well these materials perform when applied as a main component of food packaging. LÄS MER

  7. 35. Influence of Solvent Composition on Crystal Agglomeration of Paracetamol

    Författare :Eva Ålander; Åke Rasmuson; Jean-Paul Klein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Agglomeration is an important phenomenon which often controls the particle size distribution and morphology in the crystallization of organic compounds. In this thesis the influence of solvent composition on crystal agglomeration of paracetamol is investigated. LÄS MER
