  2. 1. District Heating-driven Membrane Distillation for Water Purification in Industrial Applications

    Author : Daniel Minilu Woldemariam; Andrew Martin; Massimo Santarelli; Wojciech Kujawski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; District Heating; Wastewater Purification; Heat demand; Technoeconomy; Membrandestillation; Fjärrvärme; Avloppsvattenrening; Värme-behov; Teknoekonomi; Energy Technology; Energiteknik;

    Abstract : Domestic and industrial water demands are growing globally due to population growth and rapid economic development, placing increasing strains on water resources. Wastewater effluents generated from these and other activities impact the environment and are thus subject to tightening regulation. READ MORE

  4. 2. Membrane Filtration of Wood Components − Investigation of Fouling Layer Characteristics using Fluid Dynamic Gauging

    Author : Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid dynamic gauging; wood components; cross-flow filtration; steam explosion; microcrystalline cellulose; membrane fouling;

    Abstract : As process industries transition from using fossil-based to bio-based resources, energy-efficient and highly selective operations will be required to process lignocellulosic biomass. Membrane separation, as a highly efficient operation, can be employed in the fractionation and dewatering of streams containing lignocellulosic biomass. READ MORE

  5. 3. Zeolite Membrane Separation at Low Temperature

    Author : Pengcheng Ye; Anne Julbe; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The energy consumption of separation processes accounts for a large part of the total energy consumption in chemical industry. Membrane separation processes require much less energy than the currently used thermally driven separation processes and could therefore reduce energy consumption in industry considerably. READ MORE

  6. 4. Numerical and Experimental Studies on the Effects of Flow on Drop Formation in Cross-flow Membrane Emulsification

    Author : Anna Timgren; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle image velocimetry; Drops; Force balance model; Membrane emulsification; Volume of fluids; Computational fluid dynamics;

    Abstract : Membrane emulsification is a gentle process that produces emulsions with a narrow drop size distribution, which increases the stability of the emulsion. The dispersed phase is forced through the pores in a membrane and drops are formed at the other side of the membrane where a continuous phase, flowing along the membrane surface, sweeps away the forming drops.

  7. 5. Study of MFI zeolite membrane for CO2 separation

    Author : Shahpar Fouladvand; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : Nowadays, the need and interest for renewable sources of energy has increased. Biogas is a renewable source of energy that can be considered as a sustainable substitute for natural gas. READ MORE
