Abstract:

Le concept de pivot reçoit beaucoup d'attention sur internet, dans le milieu de l'enseignement, par les accélérateurs de start-up et chercheurs en ingénierie. Toutefois, ce concept reste encore peu exploré dans le domaine scientifique et plus particulièrement en sciences de gestion. De plus, la littérature traitant du sujet n'aborde pas explicitement le processus de pivot de manière systémique en considérant l'entrepreneur, ses artefacts et les acteurs de son écosystème comme un tout indissociable. Par conséquent, l'objectif de ce travail de recherche est de comprendre le processus de pivot da

Abstract:

Mineralogical complexity and declining ore grades poses new challenges to the mining industry. From the grinding point of view, this means that in order to liberate minerals, particles would have to be ground to a finer particle size. Already, comminution is the biggest energy consumer in the concentrating mill. When particles are ground to even smaller particles sizes, costs and energy consumption increase significantly. This coupled with the fact that conventional tumbling mills are ineffective in a size range under 50 µm, has increased interest towards in the use of stirred media mills. Thi

The National Transportation Safety Board has cited deficiencies in judgement and decision-making as contributing factors in numerous general aviation accidents.

Thesis (MScEng)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: Carbon dioxide (CO2) is seen as one of the main contributors to global warming. The use of fossil fuels for power production leads to large quantities of carbon dioxide being released into the atmosphere. The released CO2 can, however, be captured by retrofitting capture units downstream from the power plant called Post Combustion Carbon Dioxide Capturing. Post combustion CO2 capture can involve the reactive absorption of CO2 from the power plant flue gas steam. Reactive solvents, such as monoethanolamine (MEA), are used for

Att begränsa globala uppvärmningen till 1,5°C kommer kräva negativa koldioxidutsläpp. En metod för att generera negativa koldioxidutsläpp är så kallad Bio-Energy Carbon Capture and Storage (BECCS). En direkt implementering av BECCS är att fånga in CO2 från rökgas som genereras vid förbränning av biomassa i en så kallad post-combustion capture-konfigurering. Post-combustion BECCS har skapat en stor resonans hos kraftverksoperatörer och pappersproducenter.

In the search for large-scale production of renewable fuels and chemicals, hydrothermal liquefaction (HTL) of biomass has emerged as one of the most promising routes.

The aim of this thesis is to gain a better understanding of the process scaling effects and to enhance the quality of the bio-crude oil product. A novel feature of this work is that it has successfully tested the HTL process in a continuous-flow (15–70 L/h) pilot-scale plant – by doing so,

Abstract:

It is becoming more important that transport agendas acknowledge complex social sustainability matters like feelings of safety and security. For developing knowledge in this context today, participatory descriptive assessments hold a strong position. However, quantitative methods providing popular transport appraisals, have a clearer impact focus, but struggle with encompassing social sustainability matters. Filling the methodological gap that exists between the participatory descriptive tradition and the quantitative impact tradition, can be vital in moving methods closer to public and policy

Abstract:

Owing to its ability to improve both spectral and energy efficiency of wireless networks, massive multiple-input multiple-output (mMIMO) has become one of the key enablers of the fifth-generation (5G) and beyond communication systems. For successful integration of this promising physical layer technique in the upcoming cellular standards, it is essential to have a comprehensive understanding of its network-level performance. Over the last decade, stochastic geometry has been instrumental in obtaining useful system design insights of wireless networks through accurate and tractable theoretical

Abstract:

With a growing concern of climate change due to increased levels of CO2 in the atmosphere, carbon sequestration has been suggested as a possible solution for climate change mitigation. Biochar,a highly carbonaceous product produced through pyrolysis, is considered a viable option due to its content of stable carbon. This work covers the investigation of the possibility to produce biocharfrom four different feedstocks, namely peat, straw, horse manure and sewage sludge. The study includes a literature study and a five-week trial period at a 500 kW pilot plant, PYREG 500, in Högdalen. The therma

Abstract:

The separation of aqueous and organic mixtures with thermal separation processes is an important and challenging task in the chemical industry. Rising prices for energy, stricter environmental regulations and the increasing demand for high purity chemicals are the main driving forces to find alternative solutions to common separation technologies such as distillation and absorption. These are mostly too energy consumptive and can show limited separation performance, especially when applied to close boiling or azeotropic mixtures. Pervaporation can overcome these thermodynamic limitations and r

Abstract:

Heightened concerns for cleaner air and increasingly more stringent regulations on sulphur content in transportation fuels will make desulphurization more and more important. The sulphur problem is becoming more serious in general, particularly for diesel fuels as the regulated sulphur content is getting an order of magnitude lower, while the sulphur contents of crude oils are becoming higher. This thesis aimed to develop a desulphurisation process (based on oxidation followed by extraction) with high efficiency, selectivity and minimum energy consumption leading to minimum environmental impac

Abstract:

Pressure swing adsorption (PSA) is a widely applied technology for separating gases, which operates based on selective adsorption on solid adsorbents. Indeed, the demand of PSA process plants for nitrogen production on industrial scale is continuously growing, as consequence of the improvements achieved in terms of efficiency, competitiveness, and cost-effectiveness. In this work, the N2-PSA pilot plant located at the Münster University of Applied Sciences, was used as study-case for the drafting of the industrial-scale basic design package of the plant. Firstly, it was shown that it is acc

Abstract:

Catalytic hydrotreating (HDT) is a mature process technology practiced in the petroleum refining industries to treat oil fractions for the removal of impurities (such as sulfur, nitrogen, metals, asphaltene). Hydrotreating of whole crude oil is a new technology and is regarded as one of the more difficult tasks that have not been reported widely in the literature. In order to obtain useful models for the HDT process that can be confidently applied to reactor design, operation and control, the accurate estimation of kinetic parameters of the relevant reaction scheme are required.

Abstract:

The topic of this thesis is carbon dioxide (CO2) capture and storage (CCS), which is a technology that is currently being promoted by industries, scientists and governments, among others, in order to mitigate climate change despite a continued use of fossil fuels. Because of the complex nature of CCS and the risks it entails, it is controversial. The aim of this thesis is to analyse how the technology may be further developed in a responsible manner. In the first part of the thesis different methods for capturing CO2 from industrial processes as well as power plants are analysed. The aim is to
