• Capital cost estimation of CO2 capture plant using Enhanced Detailed Factor (EDF) method: Installation factors and plant construction characteristic factors 

      Aromada, Solomon Aforkoghene; Eldrup, Nils Henrik; Øi, Lars Erik (Journal article; Peer reviewed, 2021)
      Capital cost is frequently estimated for new and retrofit carbon capture plants as new concepts for cost reduction emerge. Capital cost during initial cost estimation of chemical plants strongly depends on the installation ...
    • CO2stCap - Cutting Cost of CO2 Capture in Process Industry 

      Skagestad, Ragnhild; Normann, Fredrik; Gararsdottir, Stefania Osk; Sundqvist, Maria; Anheden, Marie; Eldrup, Nils Henrik; Ali, Hassan; Haugen, Hans Aksel; Mathisen, Anette (Journal article; Peer reviewed, 2017)
      This paper is a presentation of the CO2stCap project to be undertaken in the four year project period (2015 – 2019). The project focuses on partial CO2 capture in process industry and how this can be applied to reduce cost. ...
    • Combined calcination and CO2 capture in cement clinker production by use of electrical energy 

      Tokheim, Lars-André; Mathisen, Anette; Øi, Lars Erik; Jayarathna, Chameera K.; Eldrup, Nils Henrik; Gautestad, Tor (Chapter, 2019)
      The technical feasibility of electrifying the calcination process in a precalciner cement kiln system was assessed by studying different electrification concepts. Resistance-based heating was selected as it equires no CO2 ...
    • Hva koster egentlig CO2-håndtering? 

      Eldrup, Nils Henrik; Røkke, Nils Anders (Journal article; Peer reviewed, 2011)
    • Simulation and Cost Comparison of CO2 Liquefaction 

      Øi, Lars Erik; Eldrup, Nils Henrik; Adhikari, Umesh; Bentsen, Mathias Håvåg; Badalge, Jayalanka Chathurangani Liyana; Yang, Songbo (Journal article; Peer reviewed, 2016)
      Liquefaction of CO2 is an intermediate step for storage or ship transport. Two processes are suggested. The traditional method is based on external refrigeration and the other is an integrated refrigeration process. In the ...
    • Simulation and Economic Optimization of Amine-based CO2 Capture using Excess Heat at a Cement Plant 

      Ali, Hassan; Øi, Lars Erik; Eldrup, Nils Henrik (Journal article; Peer reviewed, 2018)
      In order to remove CO2 from power or process industry, a well-known method is absorption in monoethanolamine (MEA) followed by desorption, and this technology has been in operation for decades. The major challenge is the ...
    • Techno-Economic Assessment of Different Heat Exchangers for CO2 Capture 

      Aromada, Solomon Aforkoghene; Eldrup, Nils Henrik; Normann, Fredrik; Øi, Lars Erik (Peer reviewed; Journal article, 2020)
      We examined the cost implications of selecting six different types of heat exchangers as the lean/rich heat exchanger in an amine-based CO2 capture process. The difference in total capital cost between different capture ...
    • Techno-economic study of the CCMS Technology for CO2 capture from ferro-silicon production 

      Nygård, Heidi S.; Meyer, Julien; Di Felice, Luca; Eldrup, Nils Henrik; Haug, Alf Tore; Olsen, Espen (Journal article; Peer reviewed, 2019)
      Carbon Capture in Molten Salts (CCMS) is a method for capturing CO2 from a variety of flue gases related to power generation and energy intensive industry processes. The chemical principles are similar to those of the ...
