Effekten av syklisk belastning under konsolidering og styrkeprøving i en uniaxialtester
(Master thesis, 2005)For industri som bruker, behandler eller produserer partikulære materialer (pulver), er ofte de partikulære materialenes flytegenskaper av avgjørende betydning for prosessene eller for produktene. Mange bedrifter innenfor ... -
Redundans ved bruk av masse- og varmebalanser for plattformprosesser
(Master thesis, 2005)Institutt for energiteknikk (IFE) har i flere år arbeidet med bruk av balanseligninger sammen med måledata for å overvåke systemer i kjernekraftanlegg. Gjennom data reconciliation (datatilpasning) kan redundans i målingene ... -
Design av desentraliserte og suboptimale regulatorer for diskrete systemer
(Master thesis, 2005)Denne rapporten beskriver hvordan optimaliseringproblemet knyttet til optimalregulering, kan løses ved hjelp av optimaliseringsrutiner. En algoritme er laget og implementert i MatLab versjon 6.5 (R13) for optimal innstilling ... -
Transient response to shock loads in biogas processes
(Master thesis, 2006)Active culture which is in a semi steady state was extracted from an anaerobic digestion reactor, transferred to a continuously stirred batch reactor with rather small head space. 35±1ºC was controlled for the reactor to ... -
Computational study of heat transfer in subsea deadlegs for evaluation of possible hydrate formation
(Master thesis, 2007)The background for this project is the request of achieving more knowledge of the temperature and velocity fields in different subsea deadleg geometries. This is important to avoid hydrate formation in subsea equipment. ... -
Spredning og antenning av hydrogen - Background Oriented Schlieren (BOS) visualisering
(Master thesis, 2007)Rapporten er delt inn i tre deler. Første del er et litteraturstudie som omhandler tidligere undersøkelser og evalueringer av ”Background Oriented Schlieren”-fotografering (BOS) og hvilke anvendelsesområder den kan ... -
Duggpunktskontroll for gassinjeksjon og gasseksport ved Oseberg Feltsenter
(Master thesis, 2007)Naturgassen som tas opp fra gassfeltet Oseberg Feltsenter gjennomgår en rekke prosesser før eksport og injeksjon. En viktig prosess for å oppnå spesifikasjonskrav er gasstørking. Dette gjøres ved å bruke TEG, som er en ... -
Biodegradation of waste amines under anaerobic, micro-aerobic and aerobic conditions
(Master thesis, 2008)Monoethanolamines (MEA) are commonly used as adsorbent in CO2 capture plants. MEA are degraded when used and become a waste product. 3 series of BOD test as well as 9 cases of syringe batch experiments under anaerobic, ... -
Modeling and simulation of post combustion CO2 capturing
(Master thesis, 2008)A dynamic model for the chemical absorption of carbon dioxide in Monoethanolamine is developed and implemented. The model includes absorption tower, de-absorption tower, reboiler, condenser and rich/lean heat exchanger. ... -
CO2 absorption in alkaline solution
(Master thesis, 2008)Density and viscosity for monoethanolamine (MEA) solution are important for estimation of mass transfer in CO2 removal by absorption. A literature search on density, viscosity, surface tension and contact angle was performed. ... -
CFD study of a fluidized bed
(Master thesis, 2008)The aim of this thesis is to investigate the momentum exchange between the phases in a bubbling fluidized bed. The momentum exchange can be described by a drag model. Several drag models with different assumptions are ... -
Environmental production : use of waste materials in cement kilns in China
(Master thesis, 2008)This report mainly talks about utilizing the cement kiln to dispose wastes. In China, there are huge amounts of wastes can be produced every year. China government pays more attention to the environmental protection. The ... -
Supported ionic liquids as CO2 adsorbants
(Master thesis, 2008)Denne rapporten er delt inn i to deler, en teori del, og en eksperimentell del. Den teoretiske delen beskriver teori om ioniske væsker og adsorpsjon. Dette er for å få et grunnleggende forståelse av den eksperimentelle ... -
Biogas feed analysis
(Master thesis, 2008)Biogas production is regarded as the best energy recovery process from wet organic solid wastes (WOSW). Feed composition, storage conditions and time will influence the compositions of feed to biogas processes. In this ... -
Flame propagation in a transparent pipe with a single obstruction
(Master thesis, 2008)This report treats the problem of hydrogen explosions. The background for this thesis was based upon earlier work done by Bjerketvedt D., Vågsæther K. and Knudsen V. They investigated hydrogen explosions in a steel pipe ... -
