Carbon Capture Utilization and Storage in Methanol Production Using a Dry Reforming-Based Chemical Looping Technology
(Peer reviewed; Journal article, 2022)This further investigates the concept of gas switching dry reforming (GSDR) that efficiently converts the two major greenhouse gases (CO2 and CH4) into a valuable product (syngas) for gas-to-liquid (GTL) syntheses. The ... -
Non-destructive testing of prestressed concrete bridges - Experiments from field test
(Chapter, 2022)Most of the structures in the transport infrastructure are built of reinforced concrete, and many of our large bridges are built of prestressed concrete. A large part of these were built before 1980, and could theoretically ... -
Using machine learning-based variable selection to identify hydrate related components from FT-ICR MS spectra
(Peer reviewed; Journal article, 2022)The blockages of pipelines caused by agglomeration of gas hydrates is a major flow assurance issue in the oil and gas industry. Some crude oils form gas hydrates that remain as transportable particles in a slurry. It is ... -
Remote bridge inspection using optical methods
(Chapter, 2022)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
Thermo-fluid dynamics modelling of steam electrolysis in fully-assembled tubular high-temperature proton-conducting cells
(Peer reviewed; Journal article, 2022)Electrolysis based on renewable energies offers a promising carbon-free solution for hydrogen generation and storage. The recent developments of proton ceramic electrolysis cells operating at intermediate temperatures bear ... -
Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition
(Peer reviewed; Journal article, 2022)Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ... -
Kartlegging og optimalisering av industrielle konsepter for refresh-produkter av hvitfisk - Refresh
(SINTEF rapport;2022:00505 A, Research report, 2022-05-20)Målet for dette prosjektet har vært å kartlegge industrielle prosesser for produksjon av refresh-produkter av hvitfisk, vurdere hvordan enkelte deler av prosessen påvirker kvalitet, og identifisere tiltak som kan settes ... -
Variasjon i kvalitet og holdbarhet for refreshprodukter av torsk - "Refreshed"
(SINTEF rapport;2022:00504 A, Research report, 2022-05-20)Refreshed produkter, dvs. produkter som blir fryst, for deretter å tines og presenteres "refreshed" til forbruker, er et segment i vekst. I denne studien er det undersøkt hvilken effekt frysing og tining, samt kjølelagring ... -
CPFD Modeling to study the Hydrodynamics of an Industrial Fluidized Bed Reactor for Alumina Chlorination
(Peer reviewed; Journal article, 2022)Aluminum is one of the most used metals. Since aluminum has a unique combination of appealing properties and effects, it allows significant energy savings in many applications, such as vehicles and buildings. Although this ... -
Tineforsøk på torskeloins - ReFresh
(SINTEF rapport;2022:00494 A, Research report, 2022-05-12)Denne rapporten beskriver forberedelser, gjennomføring og resultater fra innledende tineforsøk i prosjekt ReFresh. Tineforsøkene var ment å avdekke effekt på drypptap og vannbindingsevne som følge av ulike tineprogram, men ... -
Study of the Thermal Performance of Industrial Alumina Chlorination Reactor Based on CPFD Simulation
(Peer reviewed; Journal article, 2022)As a part of the new sustainable aluminum production process under study, alumina chlorination plays a crucial role. The relevant process is an exothermic reaction in a fluidized bed reactor. The solid alumina reacts with ... -
Effect of Moisture, Hydrogen, and Water–Gas Shift Reaction on the Prereduction Behavior of Comilog and Nchwaning Manganese Ores
(Peer reviewed; Journal article, 2022)The ore–gas reactions in the prereduction zone in a ferromanganese furnace are largely decisive of the overall energy efficiency, carbon consumption, and climate gas emissions in ferromanganese production. An increased ... -
Kinetics Analysis of Steam Reforming of Methane on Sponge Iron
(Peer reviewed; Journal article, 2022)The kinetics of steam reforming of methane catalyzed by sponge iron was studied at temperatures between 875°C and 1050°C. Results shows that sponge iron acts as a catalyst and methane conversion is increased in higher ... -
Sensitivity and Uncertainty Analysis in a Circulating Fluidized Bed Reactor Modeling
(Peer reviewed; Journal article, 2022)As in many real applications, in the world of fine powders and small particles, there are uncertainties and vagueness in the parameters such as particle size, sphericity, initial solid void fraction, envelope density, etc. ... -
Design of a Medium-Scale Circulating Fluidized Bed Reactor for Chlorination of Processed Aluminum Oxide
(Peer reviewed; Journal article, 2022)Fluidization is a well-established and widely used technology in the process industry. The production stability and the large effective contact area between the active substances, resulting in high mass and heat transfer ... -
CPFD Simulations on a Chlorination Fluidized Bed Reactor for Aluminum Production: An Optimization Study
(Peer reviewed; Journal article, 2022)Early CPFD simulation studies on designing a fluidized bed reactor for alumina chlorination showed that the model suffers from high particle outflow and dense phase bed channeling. The present study is aimed to optimize ... -
The Effect of Impurities on γ-Alumina Chlorination in a Fluidized Bed Reactor: A CPFD Study
