Combined Calcination and CO2 Capture in Cement Clinker Production by Use Of Electrical Energy
(SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)The technical feasibility of electrifying the calcination process in a precalciner cement kiln system was assessed by studying different electrification concepts. Resistance-based heating was selected as it requires no CO2 ... -
Concentration and Temperature Effects on Water and Salt Permeabilities in Osmosis and Implications in Pressure-Retarded Osmosis
(Journal article; Peer reviewed, 2018)Osmotic power extracted from the mixing of freshwater with seawater is a renewable energy resource that has gained increasing attention during recent years. The estimated energy can significantly contribute to the production ... -
CSEM for CO2 Storage – Feasibility Study at Smeaheia to Optimise Acquisition
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)In this work, we evaluate the use of controlled-source electromagnetics (CSEM) for CO2 monitoring at Smeaheia, a possible candidate for future phases of the Norwegian full-scale CCS project. CSEM is sensitive to electrically ... -
Efficiency of CO2 Foam Mobility Control with Heterogeneous Reservoir Properties
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)We investigate how reservoir heterogeneity affects the efficiency of CO2 mobility control in saline aquifer storage. An ensemble of reservoir models is set up for simulation of CO2 injection with a quarter-five-spot well ... -
Electrochemically Enhanced Deposition of Minerals from Synthetic Reservoir Brine
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)In this paper we ask the question whether or not electrochemically enhanced deposition of minerals can be utilized to repair leakage paths existing in cement plugs in wells. Electrical polarization of two electrodes may ... -
Energy-Intensive Industry as a Practical and Cost-Effective Vector for Blue Hydrogen Exports – A Norwegian Case Study
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)As political will gathers behind the ideal of rapid decarbonization, the future looks increasingly dim for oil & gas exporters. CCS offers a pathway for continued operation in the longer-term as the world decarbonizes, ... -
Evaluation of Results from SDR Campaigns and Pilot Data
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)For ethanolamine (MEA) many degradation products have been identified and quantified, and the formation of these compounds at different process conditions should be verified. This short paper shows that lab scale experiments, ... -
Experimental Study of the use of Particles for Tracking the Interfaces in Primary Cementing of Concentric and Eccentric Wells
(SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)In this study, our recent and new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. The particles can enable us to know the precise location of the interface ... -
