Wet Gas Compression - Transients
(Master thesis, 2017)Today, most of the large and easily accessible oil and gas fields on the Norwegian continental shelf has been developed. Future production potential is found in development of fields at large depths and cost-efficient ... -
Wet Gas Compression: Experimental investigation of the aerodynamics within a centrifugal compressor exposed to wet gas
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:106, Doctoral thesis, 2012) -
Wet Gas Compression: Impeller Rig
(Master thesis, 2009)Wet gas compression technology is of great value to the oil and gas industry for boosting of unprocessed well stream and to reduce investment costs related to equipment and personnel. The growing interest in wet gas ... -
Wet Gas Compressor Performance
(Master thesis, 2014)The world s energy demand is increasing and more attention is given to increase the recovery of gas fields. Installing a compressor near the wellhead can contribute to this. Constantly changing reservoir conditions requires ... -
Wet gas compressor performance evaluation
(Doctoral theses at NTNU;2022:46, Doctoral thesis, 2022)The demand for oil and gas from the maturing Norwegian continental shelf (NCS) remains high. Even though the concern for climate change is shifting energy production towards renewables, production on the NCS is expected ... -
Wet Gas Compressor Performance: A Numerical Investigation of Thermal-Equilibrium in a Centrifugal Compressor Exposed to Wet Gas
(Master thesis, 2012)Wet gas compression and subsea compression technology has gained increased focus in the recent years. With aging fields on the Norwegian continental shelf and new discoveries in arctic regions, subsea compression could ... -
Wet Gas Compressor Transient Operation
(Master thesis, 2018)Over the past years, the oil and gas industry has directed its attention towards subsea wet gas compression. Previous research has demonstrated that the operation of subsea wet gas compressors represents challenges related ... -
Wet Gas Compressor Transients
(Master thesis, 2014)This master thesis considers three subtasks related to transient operation of wet gas compressors.HYSYS Dynamics is used to establish a dynamic simulation model in the first subtask. The model is designed to predict transient ... -
Wet Gas Compressors - Stability and Range
(Doctoral thesis at NTNU;2016:230, Doctoral thesis, 2016)The oil and gas industry is a large user of turbomachinery. The demand for oil and gas is consistently growing, and changing market conditions require innovative solutions. Operation and optimization of turbomachinery ... -
Wet Torrefaction of Biomass – Production and Conversion of Hydrochar
(Doctoral thesis at NTNU;2015:20, Doctoral thesis, 2015)Biomass is a renewable and carbon neutral energy resource which has a high potential for replacing fossil fuels. However, the use of biomass for energy applications is not straightforward. It is because native solid ... -
Wettability Alteration Measurement Using Zeta Potential
(Master thesis, 2021) -
Wettability Variations within the North Sea Oil Field Frøy
(Master thesis, 2012)Wettability is one of the most important parameters governing the rate of oil recovery from a porous medium. This thesis is a study of the wettability variations within the Frøy field in the North Sea, and its effect on ... -
Wetting Properties of Springtail Cuticles: A Quantitative Analysis
(Master thesis, 2012)With the prospect of producing superhydrophobic and mechanically stable biomimetic surfaces, the water repellent properties of springtail cuticles are investigated quantitatively. The analysis is based on apparent contact ... -
Wetting State Transitions over Hierarchical Conical Microstructures
(Journal article; Peer reviewed, 2018)Advancing in a better understanding of the physics of wetting requires to be able to develop surfaces with well‐controlled roughness by controlling the microstructure morphology. In this study, patterned truncated cones ... -
What Are Demanding Operations In Subsea Work?
(Journal article; Peer reviewed, 2018)In recent years, offshore operations have changed from a focus on anchor handling and rigging to more subsea installation and IMR (inspection, maintenance, repair). Situations where large and heavy modules are placed on ... -
“What are the carrier advantages and disadvantages of IoT cargo tracking?”
(Bachelor thesis, 2020)Teknologi utvikler seg kontinuerlig og tar en større rolle i hver dagen vår. Teknologiendringene de siste årene har har vært bratt seg og forventes å fortsette. Bransjer har blitt presset mot nytenking, og skipsfartsmarkedet ... -
