Particle deposition characteristics in the formation of Hard Grey Scale (HGS) on cold surfaces exposed to aluminium production off-gas
(Peer reviewed; Journal article, 2021)Hard Grey Scale (HGS) is a hard and strongly adhering fouling material that forms on solid surfaces impinged by the off-gas generated in the pot cells of aluminium production plants. Different theories on HGS formation ... -
Particulate emissions from electrolysis cells
(The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2011)In the dry cleaning of the exhaust gas from the aluminium cells impurities are accumulated in the finer fractions of secondary alumina from the dry scrubbers. The present work describes new methods for the determination ... -
Partitioning of non-ionic surfactants between CO2 and brine
(Peer reviewed; Journal article, 2020)The partitioning of non-ionic surfactants in a CO2/synthetic brine system was studied for a selection of surfactants at reservoir conditions for CO2 enhanced oil recovery and aquifer storage. Alkyl and alkylphenol ethoxylates ... -
Pathways to low-cost clean hydrogen production with gas switching reforming
(Peer reviewed; Journal article, 2020)Gas switching reforming (GSR) is a promising technology for natural gas reforming with inherent CO2 capture. Like conventional steam methane reforming (SMR), GSR can be integrated with water-gas shift and pressure swing ... -
