Reduction of iron oxides with hydrogen
(2021)Iron is produced from iron ore in one of two ways, either through a blast furnace, where coke is used as fuel and reduction agent, or by a direct reduction process. The blast furnace is currently dominating iron production, ... -
Alkali chloride induced superheater corrosion – Impact of percentage of molten phase
(2021)World energy consumption has doubled in the last thirty years, and projections indicate that the energy demand will increase. Carbon dioxide is the most critical greenhouse gas generated by human activity, originating ... -
The potential of lignin as a maritime biofuel
(2021)In the 1940s, efforts towards lignin valorisation were triggered by high oil prices, but today, the motives are much more varied. The movement towards a greener future to combat climate change and the expected introduction ... -
Printing and spectrometric detection of active pharmaceutical ingredients on different surfaces
(2021)Printing of pharmaceuticals is actively researched as a tailored and flexible fabricating method, towards personalized medicine. Inkjet printing is considered as a precise dosing method and in this work, theophylline is ... -
Investigation of waste heat sources and their utilization in process industry
(2021)Waste heat is a commonly used term for such heat energy that is not utilized in the process but dissipates to the environment unused. Waste heat is a by-product which can be found in various streams exiting ... -
Methods for Researching the Stratification Phenomena and Parameters Effecting it in a Cavern Thermal Energy Storage
(2021)At the moment energy companies in Finland have invested in large scale thermal energy storage to improve the efficiency of their district heating systems. This means that energy that would otherwise have beenwastedis saved ... -
Machine learning for predicting alkali salt induced high-temperature corrosion of superheater materials
(2021)Climate change due to human activities has caused a global desire to lower CO2 emissions in the hope of halting the increasing global temperature. For electricity generation, this means reducing the CO2 emissions by ... -
Production schedule optimization in an animal feed industry
(2021)This thesis focuses on the optimization of the supply chain for an animal feed plant, including product deliveries and the production schedule. A Capacitated Vehicle Routing Planning (CVRP) model has been developed to ... -
Development of a microfluidic bead-based immunoassay
(2021)The purpose of this Master’s Thesis work was to develop a prototype of a fluidic analysis method based on Wallac Oy’s solid phase, two-site immunometric assay. Immunometric assays are used for detection and quantitation ... -
Measurement of electrostatic forces for in-line quality control of ceramic slip
(2021)In this master’s thesis, done in collaboration with Geberit in Ekenäs, the goal was to determine whether a new in-line measurement probe was suitable for monitoring and controlling the slip manufacturing process. The ... -
Lipase catalyzed chemo-enzymatic epoxidation of fatty acids using ultrasound as a process intensification method
(2021)The recent trend in switching from fossil to renewable sources in the production of essential chemicals has revealed novel methods within the concept of green chemistry. This work focuses on the epoxidation of oleic acid ... -
Degradation of polydimethylsiloxane in simulated industrial process environments
(2021)Polydimethylsiloxane (PDMS) is commonly used in the Kraft process as an anti-foaming agent, which is added during the pulp-washing stage, where the pulp is separated from the black liquor. Crude tall oil (CTO) is later ... -
A Study of Glucose Transformation to Lactic acid and Methyl lactate
(2021)Lactic acid and methyl lactate are platform molecules that hold great potential within the biorefinery industry. They are currently produced through a combination of enzymatic and fermentation processes within the industry, ... -
The Potential Use of LNG in SSAB Raahe Steelworks
(2020)Steel has been produced for thousands of years, but its extensive, industrial use began during the industrialization, with the introduction of more efficient production methods, such as the blast furnace. The global ... -
Effect of Dust Sintering on Fouling of Recovery Boiler Flue Gas Ducting
(2021)Recovery boilers today are 100 times the capacity of the original design. The fuel, black liquor, used in recovery boilers has also changed. To improve the efficiency of the boiler, the fuel contains less water. Increased ... -
Characterization of Industrial Filter Materials for Improved Filter Medium Selection
(Åbo Akademi, 2019)Filter fabrics for solid/liquid separation have been analyzed and characterized in order to provide additional knowledge about said fabrics. Three different fabrics, AINO, MITO and ASKO have been studied in this thesis as ... -
Modelling of Lyocell fibre production and technical analysis of solvent recovery concepts
(Åbo Akademi, 2020)Lyocell is a type of man-made cellulosic fibre that is produced via direct dissolution of dissolving pulp in a non-volatile amine oxide or ionic liquid. The dissolved pulp is regenerated into long fibre strings by extruding ... -
Optimization of Waste Heat Recovery on Cruise Ships using Dynamic Simulation
(Åbo Akademi, 2020)The shipping industry is currently facing tightening emission regulations and demands for more efficient cruise ships to demand shipyards to find solutions for increased efficiency and lower emissions. Cruise ships still ... -
