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 (Peer reviewed; Journal article, 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 ... -
Combined calcination and CO2 capture in cement clinker production by use of electrical energy
Tokheim, Lars-Andre; Mathisen, Anette; Øi, Lars Erik; Jayarathna, Chameera; Eldrup, Nils Henrik; Gautestad, Tor (SINTEF proceedings;4, Chapter; Peer reviewed, 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 requires 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 ... -
Impact of Uncertainty of Physical Properties on CO2 Absorption Design
Øi, Lars Erik; Karunarathne, Sumudu (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)The mass transfer coefficients, interfacial area and pressure drop of a packed bed are essential properties that need to be evaluated prior to the design of a CO2 absorption column. Various mathematical models have been ... -
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 (Peer reviewed; Journal article, 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 ... -
Simulation of Condensation in Biogas containing Ammonia
Øi, Lars Erik; Bråthen, Terje; Hovland, Jon (Peer reviewed; Journal article, 2021)Condensation in raw biogas during compression is a problem because the CO2 and water in the liquid phase is very corrosive. Raw biogas typically contains 60 mol-% methane, 40 mol-% CO2, is saturated with water and may ... -
Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS
Øi, Lars Erik; Hovland, Jon (Journal article; Peer reviewed, 2018)Raw biogas typically contains 60 % methane, 40 % CO2, small amounts of other components and is saturated with water. It is a question whether raw biogas can be compressed to high pressures without condensation. The aim of ... -
Simulation of dew points in raw biogas using PR and SRK equations of state :
Bråthen, Terje; Øi, Lars Erik; Hovland, Jon (Peer reviewed; Journal article, 2019)Biogas contains mainly methane, but raw biogas can contain large amounts of CO2 and is normally saturated with water. Condensation, especially during compression, may lead to operational problems. The aim of this work is ... -
