Assessment of Combustion and Gasification Behavior in a Bubbling Fluidized Bed Reactor: A Comparison between Biomass with and without Chemical Additives
(Peer reviewed; Journal article, 2020)During the storage of biogenic materials for energy utilization, destructions by microbial attacks are inevitable. Besides material degradation, self-ignition of wood chip piles also occurs consistently. Treating the ... -
Assessment of mercury emission at Norcem's cement kiln by use of 203 Hg tracer
(Conference report, 2005)In manufacture of cement clinker, mercury (Hg) is introduced in the cement kiln system via the fuels and as constituents in the raw materials, i.e. limestone, iron ore, etc. The permissible emission of Hg to air is very ... -
Assessment of sulphur emission at Norcem's cement kiln by use of 35S-tracer
(Conference report, 2001)Although sulphur is not a major reacting species in making cement clinker, it is introduced as a pollutant in both the energy carrier (oil, coke, coal, household waste) and in the reactants (chalk, silica). Due to the ... -
Behaviour of biomass particles in a bubbling fluidized bed: A comparison between wood pellets and wood chips
(Peer reviewed; Journal article, 2019)For successful operation and design of a bubbling fluidized bed reactor handling a specific biomass, in-depth knowledge about the bed behaviour is paramount. This study compares the behaviour of a bed of sand containing ... -
Bicarbonate for microalgae cultivation: a case study in a chlorophyte, Tetradesmus wisconsinensis isolated from a Norwegian lake
(Peer reviewed; Journal article, 2021)Bicarbonate was evaluated as an alternative carbon source for a green microalga, Tetradesmus wisconsinensis, isolated from Lake Norsjø in Norway. Photosynthesis, growth, and lipid production were studied using four inorganic ... -
Bidomain Simulations of Subendocardial Ischemia: The Forward and Inverse Problems
(Journal article; Peer reviewed, 2014-09)We provide an analysis of the bidomain theory in relation to anterior subendocardial ischemia. Using the static bidomain model, this analysis explains why simulations often do not produce ST depression when the ischemia ... -
Biodiesel Production through the Transesterification of Waste Cooking Oil over Typical Heterogeneous Base or Acid Catalysts
(Peer reviewed; Journal article, 2023)For the production of biodiesel from waste cooking oil with an acid value of 1.86 mg KOH/g, five heterogeneous catalysts—Ba(OH)2, CaO, MgO, ZnO, and AlCl3—were employed. To optimize the reaction parameters of each catalyst, ... -
Bioelectrochemical CO2 Reduction to Methane: MES Integration in Biogas Production Processes
(Peer reviewed; Journal article, 2019)Anaerobic digestion (AD) is a widely used technique to treat organic waste and produce biogas. This article presents a practical approach to increase biogas yield of an AD system using a microbial electrosynthesis system ... -
Biofilm in Moving Bed Biofilm Process for Wastewater Treatment
(Chapter, 2019)A brief introduction of the long history of biofilm-based wastewater treatment is given together with basics of biofilm behavior and mechanisms in removal and transformation of pollutants. Moving bed biofilm reactor (MBBR) ... -
Biogas purification using membrane micro-aeration: A mass transfer analysis
(Journal article; Peer reviewed, 2014)When sulfur containing organic feedstocks undergo anaerobic digestion, sulfides are formed due to the biological activities of sulfur reducing bacteria. Presence of hydrogen sulfide (H2S) negatively affects the usage of ... -
Biological treatment of amine wastes generated in post combustion CO2 capture
(Journal article; Peer reviewed, 2011)The wastes generation by amine degradation is an important issue to be addressed when considering CCS schemes. Biological treatment of amine wastes can be a strategy with reasonable economy and environmental sustainability. ... -
Boiling liquid expanding vapour explosion in CO2 small scale experiments
(Journal article; Peer reviewed, 2011-04)Carbon capture and storage systems require handling large volumes of high pressure CO2. Having thorough knowledge of the related hazards is essential, as is knowing how to prevent, detect, control and mitigate accidents. ... -

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 ... -
