Abstract:

This thesis addresses industrial energy issues from a production economic perspective. During the past decade, the energy issue has become more important, partly due to rising energy prices in general, but also from a political pressure on environmental awareness concerning the problems with climate change. As a large user of energy the industry sector is most likely responsible for a lot of these problems. Things need to change and are most likely to do so considering current and assumed future governmental regulations. Thus, the energy intensive process industries studied and focused on in t

To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users. The process industry sector is one of the largest users of energy, and thus important to analyse.

Abstract:

Steelmaking industry, one of the most electricity-intensive industrial processes, is seeking for new approaches to improve its competitiveness in terms of energy savings by taking advantage of the volatile electricity prices. This fluctuation in the price is mainly caused by the increasing share of renewable energy sources, the liberalization of energy markets and the growing demand of the energy. Therefore, making the production scheduling of steelmaking processes with knowledge about the cost of the energy may lead to significant cost savings in the electricity bills. With this aim in mind,

Abstract:

The number of residential small-scale solar electric, or photovoltaic (PV) systems installed in Massachusetts has increased over the past five years. However, expanded deployment of residential solar PV may be hindered by lack of awareness of expected electricity generation of solar PV systems, and corresponding financial return. Policymakers are also interested in using limited state resources to support the installation of well-producing solar PV systems that will help meet state greenhouse gas reduction goals. Operational residential solar PV systems may provide a key to understanding elect

Energy production in power plants comes with both high costs and turnover whereas variations in the production strategy—that is, which boilers, coolers, or generators that should be running—have big impact on the economic result. This is especially true for a combined heat and power (CHP) plant where the production of district heating and electricity is linked, thus allowing for a higher flexibility in the production strategy and potential of increasing the revenue. Previous research states that thermo-economic optimization can have a great impact on economic result of power plants, but every

Abstract:

Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low. To optimize heat and power production economically, short-term planning can be applied. Short-term planning covers the production in the near future of 1-3 days. The optimization in

The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind. This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil. Both coal and oil are finite resources, created over long time scales by geological processes. It is thus impossible to extract more fossil fuels than geologically available.

Abstract:

Les microalgues sont des organismes photosynthétiques considérés pour la production d'énergie. Les photobioréacteurs sont des systèmes fermés avec des productivités plus importantes que les bassins ouverts. Cette étude concerne l'expérimentation et la modélisation d'un réacteur du type « airlift à circulation interne». Des microparticules sont ajoutées pour modéliser les concentrations d'algues dans le réacteur. Les fractions du gaz et les vitesses du liquide ne sont pas affectées par la présence de microparticules. La distribution de la lumière dans le réacteur est calculée en considérant les

Abstract:

Yara Glomfjord is the north most production facility of compound fertilizer in the world and produces annually about 500 000 tons NPK and 200 000 tons CN. The general energy system of the process plant utilizes steam as the main energy carrier for the entire production site. Yara Glomfjord has today a general lack of steam, and steam is produced in EGA boilers approximately 75% of operational time to cover all heating tasks. The main objective of this Master thesis is to analyze energy flow in in the factory to identify energy saving potential, and later to suggest improvements for the CN-evap

Abstract:

The production of photons in the energy range of 0 to 3 GeV is discussed as a signature of the creation of a quark-gluon plasma in ultrarelativistic nuclear collisions. However, they are also created in the hadronic phase. Therefore I investigate the role of the pirho → pigamma and pio → pigamma reactions in the photon emission from hot hadronic matter, and I compare their respective importance. These reactions are known to be the leading contributions. For this purpose I use diverse effective chiral Lagrangians that are in accord with known empirical properties of strong interaction

Thesis (MScEng)--Stellenbosch University, 2011.<br>ENGLISH ABSTRACT: Increasing oil prices along with the climate change threat have forced governments, society and the energy sector to consider alternative fuels. Biofuel presents itself as a suitable replacement and has received much attention over recent years. Thermochemical conversion processes such as pyrolysis is a topic of interest for conversion of cheap agricultural wastes into clean energy and valuable products. Fast pyrolysis of biomass is one of the promising technologies for converting biomass into liquid fuels and regarded as a p

Abstract:

This Thesis presents an investigation of geothermal energy production and utilization for electricity generation on the petroleum fields. According to the global energy market in Russia, the leading position takes oil and gas industry. Experts say that most of large petroleum deposits are depleted and the water cut reaches up to 80-90%. To develop such fields and deposits is not economic attractive, that is why wells with high water cut, more than 95%, are turned into abandoned wells. The technology of obtaining geothermal energy from abandoned wells allows reusing already drilled deep wells t

Abstract:

Energy is of concern for governments and economies all over the world. As conventional methods of energy production are facing the prospect of depleting fossil fuel reserves, economies are facing energy risks. With this tension, various threats arise in terms of energy supply security. A shift from intensive fossil fuel consumption to alternative energy consumption combined with the calculated use of fossil fuels needs to be implemented. Using the energy radiated from the sun and converted to electricity through photovoltaic energy conversion is one of the alternative and renewable sources to

Abstract:

Die Produktionsplanung in kommerziellen Enterprise Ressource Planning Systemen und Produktionsplanungs- und -steuerungssystemen erfolgt unter unzureichender Berücksichtigung von beschränkten Kapazitäten. Dies führt oft zu unzulässigen Plänen, welche nicht selten zu einer Verfehlung der termingerechten Bedarfsdeckung führen. Durch den Einsatz sogenannter Clearing Functions (CF) können die nicht linearen Abhängigkeiten zwischen der Arbeitslast eines Produktionssystems und der zu erwartenden Ausbringungsmenge beschrieben werden. Eine solche CF kann empirisch durch den Einsatz von Simulation ermit

Abstract:

Seaweed biomass has been identified as a potential fermentation substrate for third generation biofuel processes due to its high carbohydrate content and its potential for mass cultivation without competing for agricultural land, fresh water and fertilisers. This thesis aimed to develop and advance existing processes to convert brown seaweeds into bioethanol. The main kelp species chosen as biomass candidates were Laminaria digitata, Laminaria hyperborea, Saccharina latissima and Alaria esculenta due to their abundance in Scottish waters and their identified potential for mariculturing.
