    • A Shortcut Design for Kaibel Columns Based on Minimum Energy Diagrams 

      Ghadrdan, Maryam; Halvorsen, Ivar Johan; Skogestad, Sigurd (Journal article; Peer reviewed, 2011)
      In this paper, a shortcut procedure is proposed to design a 4-product dividing-wall column. It is based on the information derived from Vmin diagram. This has the advantage of having more meaningful guesses for energy ...

    • A simple approach for on-line PI controller tuning using closed-loop setpoint responses 

      Shamsuzzoha, Mohammad; Skogestad, Sigurd; Halvorsen, Ivar Johan (Journal article; Peer reviewed, 2010)

    • Dividing wall columns for natural gas liquefaction plants 

      Halvorsen, Ivar Johan; Dejanovic, Igor; Olujic, Zarko; Skogestad, Sigurd (Journal article; Peer reviewed, 2018)
      In order to meet current carbon dioxide emissions reduction challenges, natural gas processing and refining industries have to find the ways to minimize energy requirements of distillation operations. Building on foundations ...

    • Energy efficient distillation 

      Skogestad, Sigurd; Halvorsen, Ivar Johan (Journal article; Peer reviewed, 2011)
      Distillation is responsible for a significant amount of the energy consumption of the world’s process industry and also in the natural gas processing. There is a significant energy saving potential that can be obtained by ...

    • Multi-Product Dividing Wall Columns: A Simple and Effective Assessment and Conceptual Design Procedure 

      Halvorsen, Ivar Johan; Skogestad, Sigurd; Dejanovic, Igor; Matijasevic, Ljubica; Olujic, Zarko (Journal article; Peer reviewed, 2011)
      The objective of this paper is to further exploit and demonstrate the potential benefits of a V-min diagram based analysis, using a fifteen component feed mixture as base case. Detailed explanations are given on how to ...

    • Optimal Operation of Kaibel Columns 

      Ghadrdan, Maryam (Doktoravhandlinger ved NTNU, 1503-8181; 2014:297, Doctoral thesis, 2014)
      Kaibel distillation column performs the separation of 4 products in a dividing-wall arrangement. This column provides significant energy and capital savings compared to conventional arrangements. The focus in this thesis ...
