A Study on Densification and CO2 Gasification of Biocarbon
(Journal article; Peer reviewed, 2018) -
An evaluation of effects of fuel parameters and flue gas recirculation on NOx emissions through detailed chemical kinetics simulations
(Journal article; Peer reviewed, 2019)In this work the effects of fuel parameters and under grate flue gas recirculation (FGR) are investigated when applying staged air combustion of solid fuel for the purpose of NOx reduction. In addition to temperatures, ... -
An Approach to Update the Failure Rates of Safety Barriers Based on Operating Experience
(Peer reviewed; Journal article, 2022)Hazardous events in process plants like the leakage of dangerous substances can result in severe damage, and such an event is often defined as the TOP event of a fault tree analysis (FTA) in a quantitative risk analysis. ... -
Assessment of Transient NOx Reduction Potential in Wood Stoves
(Peer reviewed; Journal article, 2020) -
Biocarbon pellet production: Optimization of pelletizing process
(Journal article; Peer reviewed, 2018) -
A CFD Study of the Fluid Flow through Air Distribution Hoses in a Greenhouse
(Peer reviewed; Journal article, 2023)The indoor climate of a greenhouse provides the plants with favorable growing conditions that can result in faster growth and higher yields. Important parameters to control in a greenhouse are the temperature, the humidity, ... -
Characterization of liquid products from slow pyrolysis of woody biomass
(Peer reviewed; Journal article, 2022)In the present work, birch and spruce woodchips were pyrolyzed in a fixed bed reactor under different pyrolysis conditions. The effects of pyrolysis temperature and atmosphere (i.e., with and without gas purging) on yield ... -
Characterization of Residues from Entrained Flow Gasification of Wood
(Peer reviewed; Journal article, 2020) -

Current Municipal Solid Waste Management in a Large City and Evaluation of Alternative Management Scenarios
(Peer reviewed; Journal article, 2023)Sustainable waste management is a fundamental aspect in a circular economy. The focus of this work is to evaluate the performance of the current MSW management system in the city of Oslo, and to understand how to possibly ... -
A detailed experimental study on the thermal decomposition behaviour of wood pellets under inert and oxidative conditions in a fixed bed reactor
(Peer reviewed; Journal article, 2021) -
Detailed operational mapping of a grate fired Biomass combustion plant for improved combustion process control
(Journal article; Peer reviewed, 2016)Biomass combustion plants in Norway are facing stricter emission regulations and lower profitability, mostly due to low energy prices. Hence, performance optimization through improved combustion process control and/or ... -
Digital Twin Concept for Risk Analysis of Oil Storage Tanks in Operations: a Systems Engineering Approach
(Peer reviewed; Journal article, 2022)This paper presents an approach to develop a risk monitoring tool for oil storage facilities. The suggested approach is derived from the existing dynamic risk analysis (DRA) methods and the digital twin concepts. One of ... -
Dividing wall columns for natural gas liquefaction plants
(Journal article; Peer reviewed, 2018)In order to meet current carbon dioxide emissions reduction challenges, natural gas processing and refining industries have to find the ways to minimize energy requirements of distillation operations. Building on foundations ... -
Effect of calcination temperature and time on properties of steam exploded pellets
(Peer reviewed; Journal article, 2022)Carbon anodes play an essential role in the production of primary aluminium. Currently fossil carbon is used for producing carbon anodes. Reducing the carbon utilization and replacing the fossil carbon are the main routes ... -
The Effect of Feeding Strategy on Butanol Production by Clostridium beijerinckii NCIMB 8052 Using Glucose and Xylose
(Peer reviewed; Journal article, 2018)We performed fed-batch fermentations of glucose and xylose mixtures producing butanol. Our aim was to develop a feeding strategy for coping with carbon catabolite repression (CCR) and sequential utilization problems as ... -
Energy Efficiency Increase by Improved Operation and Control in Wood Stoves
(Peer reviewed; Journal article, 2023)The purpose and novelty of this work was to evaluate both the total and the transient energy efficiency of three types of modern wood stoves based on experimental results at different loads and elaborate on the level of ... -
