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 ... -
Cost and Emissions Reduction in CO2 Capture Plant Dependent on Heat Exchanger Type and Different Process Configurations: Optimum Temperature Approach Analysis
Aromada, Solomon Aforkoghene; Eldrup, Nils Henrik; Øi, Lars Erik (Peer reviewed; Journal article, 2022)The performance of a plate heat exchanger (PHE), in comparison with the conventional shell and tube types, through a trade-off analysis of energy cost and capital cost resulting from different temperature approaches in the ... -

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 Cost Estimation of CO2 Capture Using Aspen HYSYS or Aspen Plus
Dehghanizadeh, Masoumeh (Master thesis, 2023)This study presents a techno-economic assessment of an amine-based carbon capture technology.To investigate the effects of increasing the flue gas flow rate to the plant, two additional scenarios were created. In the first ... -
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 ... -
Simulation and Impact of different Optimization Parameters on CO2 Capture Cost
Aromada, Solomon Aforkoghene; Karunarathne, Sumudu; Eldrup, Nils Henrik; Orangi, Sina; Farsi Madan, Farzan; Fajferek, Katarzyna Grazyna; Sæter, Njål Torgeir; Bahri, Syaiful; Øi, Lars Erik (Journal article; Peer reviewed, 2021)The influence of different process parameters/factors on CO2 capture cost, in a standard amine based CO2 capture process was studied through process simulation and cost estimation. The most influential factor was found to ... -
