  1. 1. Drying kinetics, coalescence and agglomeration of dairy products particles

    Författare :Loredana Malafronte; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single particle; stickiness; agglomeration; spray drying; modelling; drying-kinetics; coalescence; dairy;

    Sammanfattning : Spray drying is used in the food, pharmaceutical, and chemical industries for producing powder from a liquid feed. The unique advantages of spray drying are producing powders of a specific particle size and moisture content, handling heat sensitive products, and high capacity. However, spray drying is a complex process. LÄS MER

  3. 2. On the Agglomeration of Particles in Exhaust Gases

    Författare :Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase flow; DES; particulate matter; exhaust after treatment; particle agglomeration; Lagrangian particle tracking; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. LÄS MER

  4. 3. Wettability and Agglomeration Characteristics of Non-Metallic Inclusions

    Författare :Changji Xuan; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wettability; non-metallic inclusion; agglomeration mechanism; attraction force; complex deoxidation; particle addition; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : In this thesis, both the wettability and the agglomeration characteristics of non-metallic inclusions in liquid iron/steel were studied by using both experimental results and thermodynamic considerations. The mechanisms of the wettability of different types of inclusions were discussed. LÄS MER

  5. 4. The influence of solvent composition on crystal agglomeration of paracetamol

    Författare :Eva Ålander; KTH; []
    Nyckelord :paracetamol; solvent composition; agglomeration; image analysis; principal component analysis; agglomerate strength; interfacial energy;

    Sammanfattning : This thesis deals with the influence of solvent compositionon crystal agglomeration of paracetamol. Much work has beendone on characterisation of the crystalline product.Interfacial energies have also been determined for large singlegrown crystals. LÄS MER

  7. 5. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation

    Författare :Sulena Pradhan; Inger Odnevall Wallinder; Jonas Hedberg; Eva Blomberg; Emma Strömberg; Kerstin Forsberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; freshwater; di-hydroxybenzoic acid; humic acid; copper; aluminium; manganese; dissolution; agglomeration; stability; complexation; Kemi; Chemistry;

    Sammanfattning : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.
