CONTROLLING FLUE GAS TEMPERATURE FROM FERRO SILICON SUBMERGED ARC FURNACES (SAF) USING FLUE GAS RECIRCULATION (FGR)
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Flue gas Recycling (FGR) is a well-known method for NOx reduction. A feasibility study is presented on the potential use of FGR in ferro-silicon production. The aim of the study is to illustrate how recycling of flue ... -
Coupled fluid-solid modelling of the valve dynamics in reciprocating compressors
(Science et technique du froid;, Chapter; Peer reviewed, 2022)A novel method coupling computational fluid dynamics (CFD) and finite element method (FEM) was developed to account for the complex physics of the reciprocating compressor. The developed method is based on data exchange ... -
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 ... -
Data quality issues for vibration sensors: a case study in ferrosilicon production
(Chapter, 2022)Digitisation in the mining and metal processing industries plays a key role in their modernisation. Production processes are more and more supported by a variety of sensors that produce large amounts of data that meant to ... -
Data quality issues in solar panels installations: a case study
(Chapter, 2022)Solar photovoltaics (PV) is becoming an important source of global electricity generation. Modern PV installations come with a variety of sensors attached to them for monitoring purposes (e.g., maintenance, prediction of ... -
Effects of CO2 cover gas and yttrium additions on the oxidation of AlMg alloys
(Light Metals;2019, Chapter; Peer reviewed, 2019)AlMg alloys are known to suffer from problematic oxidation that can result in significant dross formation and loss of Mg from the melt. Historically, beryllium has been used to minimize the oxidation as it forms a protective ... -
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 ... -
