  1. 1. Operating procedures and evaluation of a carbon capture pilot plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Isac Logeke; [2023]
    Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; amine absorption; pilot plant; operating procedures; chemical engineering; Chemistry;

    Sammanfattning : The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2.

    Sammanfattning : Castings of aluminum alloys are widely used in the automotive and aerospace industries since they play a significant role in improving the performance and fuel efficiency. In aluminum industries, sampling is the most common method to evaluate the inclusion levels which is a key indicator for the quality of the aluminum alloys. LÄS MER

  4. 3. Optimal Auxiliary Variable Assisted Two-Phase Sampling Designs.

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Henrik Imberg; [2016-06-22]
    Nyckelord :Anticipated variance; Auxiliary information in design; Maximum pseudolikelihood; Optimal designs; Poisson sampling; Two-phase sampling;

    Sammanfattning : Two-phase sampling is a procedure in which sampling and data collection is conducted in two phases, aiming at achieving increased precision in estimation at reduced cost. The rst phase typically involves sampling a large number of elements and collecting data on variables that are easy to measure. LÄS MER

  5. 4. Multiphase Motion Estimation in a Two Phase Flow

    Uppsats för yrkesexamina på grundnivå, Bildbehandling; Tekniska högskolan
