Gas Flotation for Subsea Produced Water Treatment - Development of a Method
(Master thesis, 2022)I oljeutvinningsindustrien er produsert vann den største avfallsstrømmen målt i volum, og fraksjonene av vann til hydrokarboner som utvinnes fra oljebrønner har en tendens til å øke over tid. For å sikre riktig håndtering ... -
Gas Flow and Pressure Drop in Charge Material in Silicon Production
(Peer reviewed; Journal article, 2022)Gassing, outbursts of high-rate gas flows through the taphole, is a phenomenon that sometimes occurs during tapping of silicon furnaces. In addition to being an HSE challenge, this might also affect the tapping, while the ... -
Gas Flow in Charges for Mn-Ferroalloy Production
(Master thesis, 2023)Et sentralt mål for ferromanganindustrien er å redusere energiforbruk og utslipp av klimagasser knyttet til produksjonen. For å bidra til å løse disse utfordringene ble PreMa-prosjektet initiert. PreMa-prosjektets mål er ... -
Gas flow through shallow sediments - A case study using passive and active seismic field data
(Journal article; Peer reviewed, 2019)Offshore Quaternary sediment sequences are generally weak and unconsolidated, and fluid flow through these rock formations is hard to predict or model. Surface flow observations, such as gas seeps, often appear random and ... -
Gas Heated Steam Reformer Modelling
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:77, Doctoral thesis, 2006)Conversion of natural gas is becoming increasingly relevant in the future as the world energy market will demand cleaner fuels, cleaner production of fuels and better utilization of the large, remote, and still undiscovered ... -
Gas Influx Handling for Dual Gradient Drilling
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:338, Doctoral thesis, 2011)New drilling technology is primarily developed when limitations of existing technology makes it difficult or impossible to reach new targets. Drilling in deep waters and in depleted reservoirs is less profitable or too ... -
Gas Ion Source Performance of the EnvironMICADAS at HEKAL Laboratory, Debrecen, Hungary
(Journal article; Peer reviewed, 2021)A coupled accelerator mass spectrometer–gas interface system has been successfully operating at the Hertelendi Laboratory of Environmental Studies, Debrecen, Hungary, since 2013. Over the last 6 years more than 500 gas ... -
Gas Lift Optimization Using Python and Prosper Well Models
(Master thesis, 2022)Arbeidet utført i denne masteroppgaven har hatt som mål å maksimere produksjon av olje innenfor begresninger på trykk, gassløftrate og andre prosessbegrensninger. Brønn-modellen, som beskriver oppførselen til en brønn når ... -
Gas liquid model for SO2: Study of the regenerable Elsorb process
(Master thesis, 2013)This is a study of the regenerable Elsorb Process which is an eco-friendly buffer system for SO2 recovery from gas streams. The buffer system consists of an aqueous solution of Na2HPO4, NaH2PO4 and Na2SO4 formed from solvent ... -
Gas phase amine depletaion created by aerosol formation and growth
(Journal article; Peer reviewed, 2017)Aerosols are systems of droplets or wet particles suspended in gases. In post combustion CO2 absorption systems aerosols can be formed by spontaneous phase transitions in supersaturated gas phases or by droplets or particles ... -
