  2. 1. Process Models for CO2 Migration and Leakage : Gas Transport, Pore-Scale Displacement and Effects of Impurities

    Author : Farzad Basirat; Auli Niemi; Karsten Jensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geological Carbon Storage; CO2 leakage; Field experiment; Laboratory experiment design; Multi-phase flow; Heterogeneity; Wettability; Pore-scale modeling; Impurity gases; Hydrology; Hydrologi;

    Abstract : Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. READ MORE

  4. 2. On Diffusion Transport Properties in Fuel Cell Gas Diffusion Layers Using the Lattice Boltzmann Method

    Author : Mayken Espinoza Andaluz; Värmeöverföring; []
    Keywords : PEFC; lattice Boltzmann method; gas diffusion layers; porosity; Gas-phase tortuosity; permeability; inertial coefficient; diffusibility; pore-scale modeling;

    Abstract : The polymer electrolyte fuel cell (PEFC) is considered as one of the most promising devices for providing efficient, clean and noiseless conversion of chemical energy to electrical energy. This device can provide electrical and thermal energy for transport, mobile and stationary applications ranging in a wide range of power requirements. READ MORE

  5. 3. Residual and critical saturation in geological storage of CO2 : results from field studies, pore-network modelling and laboratory experiments

    Author : Ramin Moghadasi; Auli Niemi; Philip Ringrose; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geological CO2 storage; Residual trapping; Gas remobilization; Field experiment; Numerical modelling; Pore-network modelling; Pore-scale imaging;

    Abstract : Geological storage of CO2 in deep saline aquifers is a promising technology in the combat to reduce the atmospheric emissions of CO2. A critical component in this solution is the estimation of aquifer’s in situ capability to store CO2. READ MORE

  6. 4. Modeling Flow and Solute Transport in Packed Beds : Applications in On-site Wastewater Treatment Systems

    Author : Amir Jourak; Krishna M. Pillai; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The use of separate phosphorus (P) filter units containing replaceable filter materials with a high P binding capacity have been suggested as an appropriate passive method to treat the P from pre-treated domestic wastewater in on-site facilities. A large number of materials have been identified and suggested as being potentially suitable for such filters. READ MORE

  7. 5. Modeling of geohydrological processes in geological CO2 storage – with focus on residual trapping

    Author : Kristina Rasmusson; Auli Niemi; Fritjof Fagerlund; Rainer Helmig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; characterization test; CO2; injection design; pore-network model; Hydrology; Hydrologi;

    Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers is one approach to mitigate release from large point sources to the atmosphere. Understanding of in-situ processes providing trapping is important to the development of realistic models and the planning of future storage projects. READ MORE
