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 ... -

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 ...
