Capacity Upgrading of Offshore Oil and Gas Production Facility
Kiritharan, Mayooran (Master thesis, 2014)The design of existing offshore processing facilities for oil and gas often need to be reconsidered after some years of production due to changes in operating conditions. One example is the Ekofisk 2/4 J facilities. Here, ... -
Design optimization of heat exchangers in topside systems for offshore oil and gas processing
Bandopadhyay, Mayukh (Master thesis, 2014)On a typical oil and gas platform, mechanical equipment units are integral parts of the topside processing system. Heat exchangers, separators, scrubbers, compressors and other equipment units are critical for the proper ... -
Eksperimentelle undersøkelser av utfrysing i naturgass-systemer: Experimental investigations of freeze out in natural gas systems
Amble, Stian (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 ... -
Electrically driven heat pumps for process heat supply in oil and gas production facilities
Vicente Lopez, Alejandro (Master thesis, 2017). -
Energy optimization of Grane production facility
Habimana, Larry (Master thesis, 2008)In order to optimize the design and operation of the Grane process facility and reduce the total energy consumption and CO2/NOX emissions, there is a need to look at ways of optimizing the total energy use. This includes ... -
Energy Solution for Floating LNG Production System
Andersen, Magnus Nordahl (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 ... -
Evaluation of CO2-precooled Nitrogen Expander Systems for Natural Gas Liquefaction
Hasle, Siv Avdal (Master thesis, 2013)This Master thesis is a continuation of a project thesis written fall 2012 ?Evaluation of Liquefaction systems for Floating LNG?. Two processes for liquefaction of natural gas for a floating unit was compared and evaluated. ... -
Evaluation of production processes for LNG in arctic climate
Borlaug, Terje (Master thesis, 2011)Most of nowadays base load LNG plants are localized in the area around equator, with stable warm air and cooling water temperature. For new LNG developments in arctic areas there are several features that differ them from ... -
Evaluering av dual-mix prosess for LNG-produksjon i arktisk klima
Just, Kristian Joakim (Master thesis, 2011)LNG-produksjon i arktisk klima innebærer store temperaturvariasjoner som har innvirkning på både utstyr og kraftproduksjon. DMR-prosessen som evalueres er luftkjølt og benytter blandet kuldemedium i begge kjølekretsene. ... -
Flow vaporization of CO2 in Microchannel Tubes
Pettersen, Jostein (KKT-rapport, 1503-0342; 2002:1, Doctoral thesis, 2002) -
Forenklet stabilisering av hydrokarbonvæske for undervannsprosessering
Hove, Sven Kraggerud (Master thesis, 2013)Stabilisering er en separasjonsprosess som kan gi et fremskritt i subsea prosessteknologi i fremtiden. Å kunne stabilisere hydrokarbonvæsker subsea, kan redusere transport-kompleksiteten ved å muliggjøre transport av et ... -
Freeze out in natural gas systems: Utfrysning i naturgass-systemer
Lavik, Vegard Førde (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 ... -
