    • Effect of Manufacturing Techniques in Pressure Drop on Triple Periodical Minimal Surface Packings 

      Zimmer, Arthur; Pacheco Araújo, José D.; Andreassen, Kari Anne; Grande, Carlos Adolfo (Peer reviewed; Journal article, 2021)
      Structured packings are important elements to enhance mass and heat transfer in the chemical industry. New techniques of manufacturing, like 3D printing, can create completely new families of solids used for this purpose. ...
    • Evaluation of simplified pressure swing adsorption cycles for bio-methane production 

      Canevesi, Rafael L S; Andreassen, Kari Anne; Silva, Edson A.; Borba, Carlos E.; Grande, Carlos Adolfo (Journal article; Peer reviewed, 2019)
      Pressure swing adsorption (PSA) is a mature technique for biogas upgrading. However, it constitutes the most expensive step to obtain fuel-quality bio-methane, particularly in small-scale units. To reduce the cost of ...
    • Experimental Results of Pressure Swing Adsorption (PSA) for Pre-combustion CO2 Capture with Metal Organic Frameworks 

      Grande, Carlos Adolfo; Blom, Richard; Andreassen, Kari Anne; Stensrød, Ruth Elisabeth (Peer reviewed; Journal article, 2017)
      Vacuum Pressure Swing Adsorption (VPSA) has already proved that it can be used for capture of CO2 from the tail gas of the PSA process for hydrogen purification. The demo operated in Port Arthur by Air Products has already ...
    • In-situ XRD studies of dolomite based CO2 sorbents 

      Arstad, Bjørnar; Lind, Anna Maria; Andreassen, Kari Anne; Pierchala, Joanna; Thorshaug, Knut; Blom, Richard (Peer reviewed; Journal article, 2014)
      Calcined dolomite (a CaOMgO material derivative of the natural mineral dolomite) has the potential as a CO2 sorbent working at high temperatures (500-650 °C) in processes like post combustion carbonate-looping, or in sorbent ...
    • Multiscale investigation of adsorption properties of novel 3D printed UTSA-16 structures
