Conceptual Design and Techno- Economic Analysis of Biomass to Liquid Processes
(Doctoral theses at NTNU;2022:334, Doctoral thesis, 2022)There is a need for diversifying energy resources for better energy security. Moreover, diversification is critical in reducing the dependency on fossil fuels and subsequent carbon emissions. The thesis outlines Biomass ... -
Conceptual design and techno-economic analysis of biomass to liquid processes
(Peer reviewed; Journal article, 2022)Advanced biofuels are produced by upgrading the syncrude from biomass gasification and subsequent Fischer-Tropsch (FT) synthesis. The technology is termed biomass to liquid process (BtL) and can be categorized into ... -
Conceptual Design of a Floating Methanol Production Unit
(Master thesis, 2013)Several configurations for synthesis gas production and methanol synthesis have been considered and simulated using the simulation tool Honeywell UniSim Design R400 and MATLAB. It was decided to use a process without recycle ... -
Conceptual Design of a Once‐Through Gas‐to‐Liquid Process Combined with Ammonia Synthesis
(Journal article; Peer reviewed, 2018)Recently, a new process has been proposed for a once‐through gas‐to‐liquid (GTL) plant suitable for offshore applications. Here, cogeneration of ammonia is suggested. This is firstly because the main ingredients for ammonia ... -
Conceptual Process Design and Simulation of Membrane Systems for Integrated Natural Gas Dehydration and Sweetening
(Peer reviewed; Journal article, 2020)Subsea natural gas processing attracts increased interest due to the smaller environmental footprint. Natural gas (NG) dehydration and sweetening are the main processing steps to avoid pipeline plugging and corrosion caused ... -
Condition Monitoring Of A Gas Turbine Using Bayesian Recurrent Neural Networks.
(Master thesis, 2020)Degradering er et problem for gassturbiner og vil resultere i redusert effektivitet. Vedlikehold blir derfor regelmessig utført for å gjenopprette effekten. For å sikre kostnadsoptimal drift kan det være gunstig å bestemme ... -
Constrained Fourier estimation of short-term time-series gene expression data reduces noise and improves clustering and gene regulatory network predictions
(Peer reviewed; Journal article, 2022)Background Biological data suffers from noise that is inherent in the measurements. This is particularly true for time-series gene expression measurements. Nevertheless, in order to to explore cellular dynamics, scientists ... -
Construction of Nanocellulose Microcapsules for Research and Sensor Applications
(Master thesis, 2018)Nanocellulose microcapsules with internal hollows have previously been found to form when cellulose nanofibrils (CNF) are added to paper pulp before drying. In an effort to study such capsules removed from the paper matrix, ... -
