High pressure equation of state for condensed phase thermodynamics
(Master thesis, 2012)In this study a search for an equation of state (EOS) that accurately predicts solids behaviour at both high pressure and temperature has been performed. Firstly, several two-parameter isothermal EOSs for solids under high ... -
Inculding Prices in Control Structure Design - Applied on a Subsea Separation System
(Master thesis, 2016)The selection of controlled variables and measurements is an important aspect of the control structure design. Using the self-optimizing control framework makes it possible to select controlled variables as combinations ... -
Investigation of Adsorption of Surfactants onto Kaolinite and Relations to Enhanced Oil Recovery Methods
(Master thesis, 2014)Surfactant flooding is a well-established enhanced oil recovery (EOR) technique, but the economic feasibility of this method is a major concern due to the substantial misplacement and loss of expensive surfactants to the ... -
Isolation and Characterization of Oil-Soluble Calcium Naphthenates in North Sea Heavy Crude Oil
(Master thesis, 2014)Naphthenic acids are a diverse group of saturated mono- and polycyclic carboxylic acids that may account for as much as 10-12 weight % of crude oil. During production at several newer oil fields, there have been discoveries ... -
Kinetic Modeling of Oxychlorination Reaction
(Master thesis, 2016)Polyvinyl chloride is a widely produced plastic polymer due to its various applications and relatively low cost. Oxychlorination of ethylene to 1,2-dichloroethane is an important step in the production of vinyl chloride ... -
Kinetic study and reactor modeling of ethylene oxychlorination
(Master thesis, 2018)Oxychlorination of ethylene to 1,2-dichloroethane is a vital step in the production of polyvinyl chloride. Polyvinyl chloride is a plastic polymer that is widely used, especially in construction. The reaction is usually ... -
Magnetic Nanoparticles for Extraction of Naphthenic Acids from Model Oil
(Master thesis, 2015)The Master s thesis aims for synthesis of magnetic nanoparticles (MNP), silica-coated magnetic nanoparticles, and their application for extraction of naphthenic acids (NA) from model oil. The present work is a part of a ... -
Modeling and Characterization of Liquid Vapor Equilibrium of N-methyl-1,3-Propanediamine for CO2 Capture - Using the Extended UNIQUAC Framework
(Master thesis, 2011)In this work the loaded MAPA system has been thermodynamically characterized. This was done by measuring the phase- and chemical equilibrium in the laboratory, as vapor - liquid - equilibrium data. A thermodynamical model ... -
Modeling Interfacial Mass Transfer during the Dynamic Evolution of the Drop Size Density Distribution of Emulsions in Turbulent Pipe Flow
(Master thesis, 2016)Denne oppgaven har fokusert på å modelllere den dynamiske utviklingen av emulsjoners dråpestørrelsesfordeling i turbulent rørstrømning med og uten massebalansen for tensider. Først, ble smaspillet mellom koalesens og ... -
Modeling of a 1,2-Dichloroethane Cracker
(Master thesis, 2015)Polyvinyl chloride (PVC) is the second most widely used synthetic polymer plastic, where the largest consumption is in the building and construction sector. PVC is mainly produced through the polymerization of the monomer ... -
Modeling of Amine Degradation in a CO2 Absorption Column at Test Centre Mongstad
(Master thesis, 2012)Two different previously conducted oxidative degradation experiments, were used as a basis of modeling monoethanolamine-degradation reactions. Literature and previous experience was used to construct reaction equations for ... -
Modelling a Multiphase Subsea Separation System
(Master thesis, 2016)With the oil and gas industry changing rapidly and new oil-fields becoming less accessible, the demand for new technology and innovative thinking is increasing. With these challenges in mind a possible solution could be ... -
Modelling and optimization of a Gas-to-Liquid plant
(Master thesis, 2012)In the last years there have been much research and development regarding gas-to-liquid plants. The fuel demands are growing bigger, and fuels from oil and coal cannot cover the demands in the future. Converting natural ... -
Modelling and Optimization of a GTL Plant
(Master thesis, 2014)A gas-to-liquid process converts gaseous carbon feedstock into more valuable products. Recent technological improvements have led to an increased interest in this production method. This master s thesis has evaluated three ... -
Modelling CO2 and H2S Solubility in Aqueous Solution of MDEA
(Master thesis, 2017)Raw natural gas contains acid gases like CO2 and H2S. These gases are important to remove for different reasons. CO2 leads to reduction in the heating value of a gas, reducing its selling value, and both CO2 and H2S may ... -
Modelling of Gas Entrainment in Slugs through use of Simulations in StarCCM+ and Mechanistic Balance
(Master thesis, 2014)Slug flow is a flow pattern existing at intermediate flow rates, or arising due to operating conditions or pipe topology. Typical slug flow is recognized by large gas bubbles flowing over a liquid film separated by liquid ... -
