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 ... -
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 ... -
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 ... -
The Effect of Impurities on γ-Alumina Chlorination in a Fluidized Bed Reactor: A CPFD Study
(Peer reviewed; Journal article, 2022)Alumina is one of the most widely used materials today, with a total annual production of millions of tonnes of highly pure alumina. A large portion of this is used to make metal aluminum. Apart from that, a growing amount ... -
Fluidized bed calcination of cement raw meal: Laboratory experiments and CPFD simulations
(Peer reviewed; Journal article, 2020)The chemical and thermal processes associated with the decarbonation and fuel combustion in the cement kiln process produce a large amount of carbon dioxide (CO2) contributing with around 8 % of the global CO2 emissions. ... -
Monitoring of Erosion in a Pneumatic Conveying System by Non-intrusive Acoustic Sensors – A Feasibility Study
(Peer reviewed; Journal article, 2019)This paper presents the results of a study where the feasibility of a non-invasive acoustic measurement method was tested for monitoring of erosion in a pneumatic conveying system during the ... -
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. ... -
Simulation and Impact of different Optimization Parameters on CO2 Capture Cost
(Peer reviewed; Journal article, 2021)The influence of different process parameters/factors on CO2 capture cost, in a standard amine based CO2 capture process was studied through process simulation and cost estimation. The most influential factor was found to ... -
Simulation of Condensation in Biogas containing Ammonia
(Peer reviewed; Journal article, 2021)Condensation in raw biogas during compression is a problem because the CO2 and water in the liquid phase is very corrosive. Raw biogas typically contains 60 mol-% methane, 40 mol-% CO2, is saturated with water and may ... -
Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS
(Journal article; Peer reviewed, 2018)Raw biogas typically contains 60 % methane, 40 % CO2, small amounts of other components and is saturated with water. It is a question whether raw biogas can be compressed to high pressures without condensation. The aim of ... -
Simulation of dew points in raw biogas using PR and SRK equations of state :
(Peer reviewed; Journal article, 2019)Biogas contains mainly methane, but raw biogas can contain large amounts of CO2 and is normally saturated with water. Condensation, especially during compression, may lead to operational problems. The aim of this work is ... -
