Calculation and Simulation of Generator Protection Relay Settings at Hydropower Plants
(2022)
Vattenkraft är en förnybar energikälla där grundidén är att omvandla energin från de forsande vattenmängderna till elektrisk energi. Fenomenet kallas elektromagnetisk induktion, vilket uppstår i generatorer.
Generatorerna ...
Synthesis of sugar-based polymerizable materials for hydrogel preparation
(2022)
To match the growing need for biodegradable, biocompatible and biobased materials, this thesis explored the possibilities of the synthesis of bio-based (photo)polymerizable materials from sugars and sugar alcohols and the ...
Tuning strategies for control of integrating systems with model predictive control
(2022)
The objective of this thesis was to verify the suitability of Valmet’s own MPC solution, DNAMPC2, when applied to a common system encountered in process industry and biofuels processing. An extensive literature study was ...
Hydrofobering av handark med ASA – Inverkan av stabiliseringsmedel i olika mäldtyper
(2022)
Genom hela papprets historia har modifiering av papprets egenskaper varit av intresse. Ett sätt att modifiera egenskaperna är genom användning av olika tillsatsämnen. Exempelvis genom att tillsätta hydrofoberingsmedel som ...
Carbon dioxide capture from humid exhaust air and flue gases
(2022)
Carbon capture and storage (CCS), as well as utilisation of carbon dioxide (CO2), has become an increasingly important research area in order to achieve the goals set by the European Commission for the EU to become climate ...
Hydrogen reduction of iron oxides : Experimental study
(2022)
Steel is one of the modern world’s core pillars in engineering and construction materials, but the steel production causes large carbon dioxide emissions. The steel industry needs to reduce its carbon emissions to prevent ...
Techno-economic analysis of offshore wind-based hydrogen production in western Finland
(2023)
Finland has one of the most ambitious climate targets in the world, to reduce greenhouse gas emissions by 70% and become climate neutral by 2035. The rising average global temperature contributes to this determined goal ...
Thin-layer composite reference electrodes
(Åbo Akademi, 2020)
In this thesis work the performance and feasibility of a thin layer polymer:salt composite reference electrode was assessed, in an attempt to further miniaturize the all solid-state reference electrode previously made. The ...
Heat recovery solutions for a copper electrolysis refinery
(2023)
This thesis was produced to provide Boliden Pori Refinery with a solution for how to utilize waste heat efficiently in their electrolysis plant. The project was presented to utilize heat pumps to recover heat from the ...
