Advanced exergy analysis of the oil and gas processing plant on an offshore platform: A thermodynamic cycle approach
Sheng, Juejing; Voldsund, Mari; Ertesvåg, Ivar Ståle (Peer reviewed; Journal article, 2023)Ambitious targets on reduction of greenhouse-gas emissions have motivated further studies to improve energy efficiency in offshore gas and oil production. Identifying the causes of inefficiencies and the improvement ... -
Evaluation of a North Sea oil platform using exergy analysis
Jøssang, Knut (Master thesis, 2013)The motivation is to explore the applicability of exergy analysis as an evaluation and monitoring toolfor an offshore platform. The focus should be turned from energy efficiency to exergy efficiency,because to use an ... -
Exergy analysis of offshore oil and gas processing
Voldsund, Mari (Doktoravhandlinger ved NTNU, 1503-8181; 2014:155, Doctoral thesis, 2014)Oil and gas extraction have been responsible for 25—28% of the total greenhouse gas emissions in Norway the last 10 years. The part from offshore oil and gas processing, including power production, flaring, and cold ... -
Modelling distillation with non-equilibrium thermodynamics
Voldsund, Mari (Master thesis, 2009) -
New technologies for purification and carbon capture in hydrogen production from natural gas
Skrebergene, Kristin (Master thesis, 2015)In a society increasingly concerned with environmentally friendly solutions for energy extraction, hydrogen is expected to be an important energy carrier. Hydrogen can originate from various feedstocks, where fossil fuels ... -
Paving the way for sustainable decarbonization of the European cement industry
Cavalett, Otavio; Watanabe, Marcos D. B.; Voldsund, Mari; Roussanaly, Simon Nathanael; Cherubini, Francesco (Peer reviewed; Journal article, 2024)Cement production is a main source of carbon emissions. Decarbonization options exist, but their climate change mitigation potential, feasibility and environmental implications are still unclear. Here we assess 15 ...
