Capital cost estimation of CO2 capture plant using Enhanced Detailed Factor (EDF) method: Installation factors and plant construction characteristic factors
(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 ... -
Carbon dioxide emission reduction by increased utilization of waste-derived fuels in the cement industry
(Conference report, 2007)Considerable reductions in Norway's emissions of greenhouse gases like CO2 are required to meet the commitments of the Kyoto Protocol. CO2 emissions from cement clinker production originate from decarbonation of limestone ... -
Carbon dioxide solubility in mixtures of methyldiethanolamine with monoethylene glycol, monoethylene glycol–water, water and triethylene glycol
(Peer reviewed; Journal article, 2020)Carbon dioxide solubility in non-aqueous and aqueous mixtures of methyldiethanolamine (MDEA) with monoethylene glycol (MEG) was studied due to the relevance of these solvents for the combined acid gas removal and hydrate ... -

Categorising area models for stormwater fees at propert level: A literature review
(Journal article, 2022)Worldwide, the increasing challenges due to stormwater run-off in urban areas are well known. Authorities need to be prepared for emergency situations and have plans for preventive measures to avoid flooded properties and ... -
CCS in the Skagerrak/Kattegat area
(Journal article; Peer reviewed, 2011-04-01)This paper presents an ongoing project with the aim to assess a CO2 infrastructure in the Skagerrak/Kattegat region (the sea bordered by north of Denmark, south coast of Norway and the west coast of Sweden). The area ... -
CFD Study of Particle Flow Patterns in a Rotating Cylinder Applying OpenFOAM and Fluent
(Journal article; Peer reviewed, 2017)A rotating cylinder (RC) is a common type of reactor used in the industry, the most typical example being a cement kiln. The particle flow pattern inside such a unit is necessary for the mass and energy transfer, and this ... -
Characterization of a medium velocity deluge nozzle for offshore installations
(Peer reviewed; Journal article, 2021)It is important to study the characteristics of the nozzle of the deluge spray to comply with the standards developed by the petroleum industry for offshore installations in Norway. Due to the stochastic nature of the ... -
Characterization of biomass wood
(Journal article; Peer reviewed, 2016)Biomass is a renewable energy resource and can replace the use of fossil fuels, such as coal. Overgrown forests and fields are about to become a noticeable problem, because the rate of woodcutting is too low compared with ... -
Chemical equilibrium model to investigate scaling in moving bed biofilm reactors (MBBR)
(Peer reviewed; Journal article, 2019)Moving bed biofilm reactor (MBBR) is a robust, flexible and compact technology for treatment of medium to high strength wastewater. However, while treating with high concentration of ammonium, phosphorus and metal ions, ... -
