Fractionation and Characterisation of Enzymatic Hydrolysis Lignin
(2022)Lignin is one of the major components in lignocellulosic biomass and the most abundant aromatic building block in nature. Technical lignins extracted from either pulping or biorefining processes provide a variety of complex ... -
A balance-based study of the combustion in blast furnace cowpers
(2021)This thesis focuses on modelling and simulation of different firing conditions in cowpers that are a part of a steelmaking process. The cowpers are regenerative heat exchangers that preheat the blast air into the blast ... -
Catalysts for slurry-phase hydrotreating of bio-oil
(2021)The European Green Deal, a policy initiative set by the European Commission, aims to reduce greenhouse gas (GhG) emissions, and ultimately achieve an economy with net-zero GhG emissions by 2050. Achieving these targets ... -
Compounding Toolbox for Polypropylene Film Recycling
(2021)The recyclability of materials and plastics in general has been discussed a lot in recent years. The majority of the plastic waste ends up in landfills and is being incinerated for energy. On the other hand, the recycling ... -
Hydrodeoxygenation of lignin-derived model compound isoeugenol over Fe-, Ni-, and Fe-Ni-supported on zeolites
(2021)As the world is transitioning away from fossil fuels, lignocellulosic biomass is scrutinized as a source of renewable fuels and chemicals. Political motivations and environmental concerns have increased the research in ... -
Control of the particle size distribution of a cement grinding circuit
(2021)For the past decades, the Blaine value has been the predominant characteristic when controlling the process parameters of a cement grinding circuit. The Blaine method measures the permeability of the cement, and therefore, ... -
Non-halogenated fire retardant additives for an opaque exterior wood paint
(2021)This thesis focuses on finding effective and environmentally friendly fire retardant (FR) formulations for opaque exterior wood paints. The utilisation of green chemistry and incorporation of mineral-based FRs were deemed ... -
Inventory and management of process wastewater streams in a pharmaceutical production plant in Finland
(2021)Pharmaceuticals and their effects on the environment have become continually a more and more interesting topic. Even though only 2% of all European API (Active Pharmaceutical Ingredient) discharges are from the pharmaceutical ... -
Development of a novel artificial nose with conductive polymers of 3,4-ethylenedioxythiophene and its functionalised derivatives
(2021)Artificial noses are analytical instruments inspired by the human olfactory system and have been applied for qualitative analysis in many industrial fields, agriculture, forestry, environmental monitoring as well as medical ... -
Framställning av högbarriärpapper med reversgravyr
(2021)Målet med arbetet var att tillverka ett pappersbaserat barriärmaterial genom dispersionsbestrykning. Som substrat användes två papperssorter och bestrykningen bestod av barriärdispersioner med olika funktioner. Dispersionerna ... -
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 ...
