Eksperimentelle undersøkelser av utfrysing i naturgass-systemer: Experimental investigations of freeze out in natural gas systems
(Master thesis, 2009)Hensikten med denne masteroppgaven er å undersøke problemer knyttet til frysepunkt og utfrysning av kritiske komponenter ved naturgasskondensering. Utfrysing og plugging av rør og varmevekslere er en alvorlig utfordring ... -
Energieffektiv hydrogenlagring: eksergianalyse av adsorpsjon
(Master thesis, 2012)Hydrogenlagring er en nøkkelteknologi for etablering av en hydrogenøkonomi. Adsorpsjon er en av hydrogenlagringsteknologiene som for tiden utforskes sammen med hydrogen lagret som komprimert gass, væske, og i metallhydrider. ... -
Energy Analysis of Evaporator System in Fertilizer Production
(Master thesis, 2012)Yara Glomfjord is the north most production facility of compound fertilizer in the world and produces annually about 500 000 tons NPK and 200 000 tons CN. The general energy system of the process plant utilizes steam as ... -
Energy Integration Opportunities in Zero Emission LNG Re-Gasification
(Master thesis, 2011)Due to the increasing demand for LNG, more environmental friendly regasification solutions are of interest. Aker Solutions has developed a concept for zero emission regasification of LNG, where the regasification train is ... -
Energy Solution for Floating LNG Production System
(Master thesis, 2012)This report considers different energy solutions for a floating LNG production vessel. The two alternatives analyzed are gas turbine and steam turbine. In addition to being stand-alone alternatives they are the basis for ... -

(Master thesis, 2010)A literature survey of LNG processes suitable for offshore environment has been evaluated. Thesurvey has been performed with emphasis on space requirements, complexity, efficiency and safety.Thermodynamics theory is described ... -
Experiments and Modelling for the Control of Riser Instabilities: Forsøk og simulering for regulering av ustabil strøm i stigerør
(Master thesis, 2010)Multiphase flowline-riser systems sometimes encounter fluctuations in flow rate, pressure and liquid hold-up characterized as severe slugging. Slugging is undesirable because the piping and downstream receiving facilities ... -
Fordamping og kondensasjon i varmerør med kalium som arbeidsmedium
(Master thesis, 2011)In order to reduce energy consumption, high temperature heat recovery is of great interest in industry. Liquid metal heat pipes are of special interest due to their superior thermomechanical properties. This master s thesis ... -
Fractal modelling of turbulent flows: Subgrid modelling for the Burgers equation
(Master thesis, 2011)The stochastically forced Burgers equation shares some of the same characteristics as the three-dimensional Navier-Stokes equations. Because of this it is sometimes used as a model equation for turbulence. Simulating the ... -
Freeze out in natural gas systems: Utfrysning i naturgass-systemer
(Master thesis, 2009)The motivation of the work is to increase the knowledge about thermodynamic modeling of freezeouts in natural gas systems and a deeper understanding of the phase behavior of natural gasmixtures, due to the problems experienced ... -
Frictional pressure-drop models for steady-state and transient two-phase flow of carbon dioxide
(Master thesis, 2012)Related to the technology of CO2 capture, transport, and storage (CCS), an accurate transport model which predicts the behaviour of carbon-dioxide mixtures during steady-state and transient situations, is needed. A correct ... -
FSI-analysis of a Francis turbine
(Master thesis, 2012)Sediment erosion in Francis turbines is a big problem in hydropower plants in and around the Himalayas. The sediment composition in the rivers contains high levels of the hard mineral quarts. When the sediments enter the ... -
Gas Compression Tool Validation
(Master thesis, 2011)A decline in field developments on the Norwegian Continental Shelf over the last years has led to an increase in tie-ins of smaller- and more stranded fields to the existing production facilities. This results in more ... -
Gas Turbine Optimum Operation
(Master thesis, 2010)Many offshore installations are dependent on power generated by gas turbines and a critical issue is that these experience performance deterioration over time. Performance deterioration causes reduced plant efficiency and ... -
