Optimization of a steel plant utilizing converted biomass
(Åbo Akademi - Åbo Akademi University, 2016-06-10)
Modeling and analysis of blast furnace drainage
(Åbo Akademi University, 2020-10-02)
The blast furnace is the prevailing unit process for iron-making in the steelmaking process and the present growing global demand for steel leads to higher requirements set on the efficiency and productivity of the process. ...
Eddy break-up based models for industrial diffusion flames with complex gas phase chemistry
(Åbo Akademi - Åbo Akademi University, 1998-12-11)
In this thesis, two types of models used in the CFD modeling of practical combustion devices with a turbulent flow are investigated. The models are applied to a number of test cases, but the goal of the investigations are ...
Production of magnesium carbonates from serpentinites for CO2 mineral sequestration : optimisation towards industrial application
(Åbo Akademi - Åbo Akademi University, 2015-12-17)
Global warming is one of the most alarming problems of this century. Initial scepticism concerning its validity is currently dwarfed by the intensification of extreme weather events whilst the gradual arising level of ...
Towards sustainable Iron- and steelmaking with economic optimization
(Åbo Akademi - Åbo Akademi University, 2014-04-04)
The iron and steelmaking industry is among the major contributors to the anthropogenic emissions of carbon dioxide in the world. The rising levels of CO2 in the atmosphere and the global concern about the greenhouse effect ...
Experimental and discrete element simulation studies of bell-less charging of blast furnace
(Åbo Akademi - Åbo Akademi University, 2013-03-15)
This thesis presents an experimental study and numerical study, based on the discrete element method (DEM), of bell-less charging in the blast furnace. The numerical models are based on the microscopic interaction between ...
Production of Mg(OH)2 from Mg-silicate rock for CO2 mineral sequestration
(Åbo Akademi - Åbo Akademi University, 2012-12-13)
Sequestration of carbon dioxide in mineral rocks, also known as CO2 Capture and Mineralization
(CCM), is considered to have a huge potential in stabilizing anthropogenic CO2 emissions. One
of the CCM routes is the ex ...
Segregation of powder mixtures in silos with particular reference to dry mineral-based construction materials
(Åbo Akademi - Åbo Akademi University, 2012-04-20)
Structural and operational optimisation : applications in energy systems
(Åbo Akademi - Åbo Akademi University, 2007-12-14)
In this work mathematical programming models for structural and operational optimisation of energy systems are developed and applied to a selection of energy technology problems. The studied cases are taken from industrial ...
Model-based estimation of liquid flows in the blast furnace hearth and taphole
(Åbo Akademi - Åbo Akademi University, 2013-10-11)
This thesis presents a set of methods and models for estimation of iron and slag flows in the blast furnace hearth and taphole. The main focus was put on predicting taphole flow patterns and estimating the effects of various ...
