Droplet Deposition in High- Pressure Natural-Gas Streams
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:110, Doctoral thesis, 2010)The Norwegian University of Science and Technology has been leading a project that investigates the phenomena related to high pressure gas liquid separation (HiPGLS) in natural-gas streams. At high pressures, liquid from ... -
Dry reforming of methane over Zr- and Y-modified Ni/Mg/Al double-layered hydroxides
(Journal article; Peer reviewed, 2018)Zr- and Y-promoted Ni/Mg/Al double-layered hydroxides were investigated in dry reforming of methane, DRM (10% CH4, CH4/CO2 = 1, GHSV = 20,000 h−1) for the first time. Modification of the double-layered hydroxides with 5 wt% ... -
DT2_2017_1 Degradation and corrosion of amines (from a structural perspective)
(Research report, 2017)Degradation and corrosion of amine solutions in post combustion CO2 capture plants increases the cost of the process due to operational problems, the need for high quality material in the plant and reduction of the solvent's ... -
Dual-function catalysis in propane dehydrogenation over Pt-1-Ga2O3 catalyst: Insights from a microkinetic analysis
(Peer reviewed; Journal article, 2020)The kinetics of propane dehydrogenation over single‐Pt‐atom‐doped Ga2O3 catalyst has been examined by combining density functional theory calculations and microkinetic analysis. The doping of Pt not only can improve the ... -

Dynamic Co-Cultivation Process of Corynebacterium glutamicum Strains for the Fermentative Production of Riboflavin.
(Journal article, 2021)Residual streams from lignocellulosic processes contain sugar mixtures of glucose, xylose, and mannose. Here, the industrial workhorse Corynebacterium glutamicum was explored as a research platform for the rational utilization ... -
Dynamic Extremum Seeking Control Using ARX model
(Master thesis, 2018)In the design of the dynamic ESC, a wave perturbation is decided to be not a sinusoidal wave but a pseudo-random binary sequence(PRBS) wave. The reason behind this is that diverse frequencies in the PRBS wave make the ARX ... -
Dynamic model and Optimization of Recirculating Aquaculture System
(Master thesis, 2021)Abstract will be available on 2024-06-30 -
Dynamic modeling and optimalization of the cheese making procedure
(Master thesis, 2017)This thesis has successfully derived an dynamic model based on analytic solutions for production of semi-hard cheeses on the basis of raw milk from the cattle breed Norwegian red. The main emphasis has been to create a ... -
Dynamic modeling of the solvent regeneration part of a CO2 capture plant
(Journal article; Peer reviewed, 2013)In this work, a system of unit operations is modeled and implemented in MATLAB for dynamic simulation of the regeneration part of the CO2 capture process. The system consists of a stripper, a reboiler and a condenser, and ... -
Dynamic modelling of a Hydrocracker
(Master thesis, 2016)Different types of petroleum refining processes were considered to be modelled in the Kongsberg dynamic modelling software K-Spice. Multiple oil and gas processing units exist in the model library, which begs the question ... -
Dynamic Optimization and Parameter Estimation used on an Extrusion Press for Aluminium
(Master thesis, 2022)I dag blir aluminium brukt i flere og flere produkter. Noen av disse, som radiatoren i moderne biler, krever veldig presise produksjonsmetoder. Her brukes tynne, hule profiler som varmevekslere, og de produseres ved ... -
Dynamic Simulation of Heat Exchanger with Multicomponent Phase Change
(Master thesis, 2017)A dynamic model for a heat exchanger with multicomponent phase change, part of reliquefaction cycle of natural gas, is developed. The finite control volume method is used to spatially discretize the heat exchange intro a ... -
Dynamic wettability alteration for combined low salinity brine injection and surfactant flooding on silica surface
(Peer reviewed; Journal article, 2020)Experimental results of dynamic contact angle measurements of low salinity brine and combined low salinity water and surfactant flooding (LSW–SF) on silica surface are presented in this study. Dynamic contact angle experiments ... -
Dynamics of Regulatory Networks in Gastrin-Treated Adenocarcinoma Cells
(Journal article; Peer reviewed, 2014)Understanding gene transcription regulatory networks is critical to deciphering the molecular mechanisms of different cellular states. Most studies focus on static transcriptional networks. In the current study, we used ... -
Dynamisk modellering og simulering av gastrin-nettverk i kreftceller
(Master thesis, 2013)Fordøyelseshormonet gastrin regulerer utskillelse av magesyre samt at det kontrollerer vekst og oppbygging av membranen i magesekken. Hormonet er assosiert med flere krefttyper i fordøyelsessystemet. En av nøkkelresponsene ... -
Early field planning using optimisation and considering uncertainties - Study case: Offshore deepwater field in Brazil
(Peer reviewed; Journal article, 2021)During early phases of oil field development, field planners must decide upon the optimal number of wells and optimal field plateau rate, usually by performing sensitivity studies. These design choices are then “frozen” ... -
