Abstract:
Multitube T-junctions can be used as an oil-water-gas pre-separator in the oil and gas industry. In this paper, the mixture model, coupled with the k-ε turbulent model, was applied for a simulation of the oil-water-gas three-phase flow characteristics in the multitube T-junction separator. The oil droplet size ranged from 1 to 4 mm. The water content ranged from 5% to 20% and the gas content from 3% to 25%. According to the phase separation results for different droplet sizes, it was found that, as the oil droplet size increased, the water content at the water outlet initially increased and then tended to be stable. Therefore, it was necessary to increase the oil droplet size through corresponding measures before flowing into the T-junction for separation. For the separator with an inner diameter of 50 mm, the oil content at the inlet had a great influence on the water-oil separation performance, and the water-oil separation performance was obviously improved as the oil content decreased. Owing to increased residence time, the oil content had little influence on the water-oil separation performance when the separator with an inner diameter of 100 mm was applied. Moreover, for the separator with an inner diameter of 100 mm, the oil content had little influence on the degassing effect, and more than 90% of the gas could be discharged from the gas outlet. The separation performance of the multitube T-junction separator became worse as the inlet gas content increased.

Abstract:
Crude oil separating is an important technological process in the petroleum industry. Pipe separation technology (PST) is a new kind of separating method in oil-water-gas separation. To compare with conventional gravity separators, the new separator based on PST is low weight, low cost, efficient and convenient to maintain. This paper introduces this new compact separator, technological process and performance test. The test results show that the compact separator has good separating effect. When the water-cut inlet is from 50% to 60%, and the mixture flow rate is from 40 t/hr to 100 t/hr, the water-cut in oil outlet is less than 5%, and the oil-cut in water is less than 100 mg/l.

Abstract:
CFD (computational fluid dynamics) is a good method for simulation of the oil-gas separator. When the volume concentration is less than 10%, the oil particle tracks can be simulated by DPM （Discrete Phase Model）. The results show that the separation efficiency is obviously affected by the diameter of separator air-outlet, the diameter of separator oil-outlet, and the angle of separator cone. But the quantified analysis on separation efficiency is difficultly brought forward by CFD. RSM (response surface methods) can help to identify factors influencing the responses by experiments. Finally, the optimum responses and design parameters will be obtained altogether.

Abstract:
Separators play an important role in the basis of the technological scheme and field preparation of oil and gas. Separation is the process of oil separation from gas. Depending on the requirements for the feedstock, separators are distinguished according to the principle of operation and purpose. In this paper, the company "PT Pertamina EP Asset 3 Subang", Indonesia (Nirajani) is considered as an example. Dimensions, efficiency, reliability of equipment, capital and operating costs are the main indicators of separator work and productivity. "Subang PT Pertamina EP Asset 3 Subang" collection station has 3 horizontal two-phase separators (high pressure, low pressure and test separator). In 2020, it is planned to increase the extraction of raw materials. In this regard, the aim of this work is to modernize the existing two-phase horizontal separator operated at the field. To achieve this goal, it is necessary to study the design of the existing separator, and calculate its performance (Nirajani). After all the calculations, it is necessary to choose a separator suitable for performance. Modernization of the existing separator is economically feasible for this enterprise.

Abstract:
Fluids produced from oil reservoirs typically contain oil, natural gas, water, sediments, in varying amounts, and contaminating gases. Considering that economic interest usually targets mostly oil and gas, primary processing is used to separate water/oil/gas, in addition to treating these phases. Therefore, the well stream should be processed as soon as possible after reaching the surface. Separator vessels are among the main equipment used at surface production facilities, being responsible for the separation of the produced phases. This work focuses on studying the fluid dynamic behavior in a horizontal three-phase separator. To accomplish this goal, we used the computer fluid dynamics software ANSYS CFX. First, we performed a detailed analysis of a “Standard Case” to understand in detail the entire separation process within the vessel. The results show the three phases through the simulation time, analyses of the separation efficiency, different fluids flow lines, pressure gradient inside the vessel, and effect of the diverter baffle. It also considers a variation of fluid flow at the inlet of the separator. These analyses include pictures of all cases studied. Afterwards, some parameters of the standard case were altered to evaluate its influence on fluid dynamics behavior and the functioning of the separator vessel. At last, we analyzed the influences of oil density and viscosity on the separation. The oil quality affects the primary separation directly, as the oil density and viscosity increase, for example, increases the drag between the fluids and decreases the rate of sedimentation, which stickles the separation process difficult. Two out of the three cases generated satisfactory results. The simulation with the heaviest oil presented the worse results.

Abstract:
Aiming at the low efficiency problem of the traditional gas-oil separator, this paper put forward a centrifugal gas-oil separator. In order to identify out the interior fluid field character of centrifugal gas-oil separator, RANS equation, RNG k-ε model and discrete phase model was applied to simulate the interior fluid field character and separation efficiency of centrifugal gas-oil separator. The simulation results showed that the flow field in the disc clearance was mainly laminar flow, and the flow field at the import and export of the disc was turbulence. Meanwhile, the velocity and pressure of the interior fluid field were equably distributed, the velocity and pressure in the disc clearance fluctuate in a tight range along vertical direction, and decrease along horizontal direction, and the particles in the disc clearance were distributed uniformly. The separation efficiency was 96.6% and the results met the design requirements.

Abstract:
Gas anchor is also known as downhole oil and gas separator. It plays a role of separating the gas and oil before the fluid flows into the pump, thus to eliminate the influence of gas and improve pump efficiency. It can also extend the lifetime of the equipment and increase the oil well output. On the analysis of factors affecting the efficiency of gas anchor, I built 3D models in Gambit on the basis of the blueprint of multi-cup isoflux gas anchor. I used Fluent to calculate the multi-cup isoflux gas anchor separation of oil and gas with laminar flow model. Then I got the distribution of speed and pressure in the multi-cup isoflux gas anchor and derived the formula of local resistance ratio. Learned that on the application of the multi-cup isoflux gas anchor the pumping wells pump efficiency enhances on an average of more than 25%.

Abstract:
A heat pump in the aerospace industry can significantly reduce the area of radiator by elevating the rejection temperature. Especially for a Lunar base, the heat pump can improve the heat rejection capability of the thermal control system to adapt the high-temperature environment. However, gravity on the Lunar (about 1/6 g) may have an adverse impact on a gas-oil separator of the heat pump, and solving this problem is the key for a heat pump used on Lunar base. At present, the gas-oil separator all based on gravity separation theories, the researches under low or micro gravity were blank. In this work, a gravity separation model based on a single-particle principle was built, and the effects of the vapor velocity, the oil droplet initial velocity, and the oil droplet diameter were investigated under normal gravity. Then the variations of the separation efficiency under Lunar gravity were discussed and the numerical calculation results showed that the separation efficiency was reduced when the vapor velocity or droplet initial velocity increased in a certain height of the separator whenever under normal or Lunar gravity. Particularly, the separation efficiency under Lunar gravity was reduced from 99% to 55% than it under normal gravity.

Abstract:
Two main topics are treated in this doctoral thesis from a theoretical and computational point of view: the gas capture and separation from post-combustion flue gases, and the enhanced oil recovery from oil reservoirs. The first topic evaluates the separation of CO2 using three different materials. First, several zeolites from the Faujasite family are studied with a combination of Density Functional Theory (DFT) and Monte Carlo methods. The former is employed to understand the driving mechanisms of adsorption, whereas the latter served to assess the separation of CO2 from a flue gas formed by a ternary mixture of CO2, N2 and O2. Second, the adsorption of CO2, N2 and SO2 into Mg-MOF-74 obtained through DFT calculations is presented to determine the most fundamental gas/MOF interactions. The results are then coupled to a Langmuir isotherm model to derive the macroscopic adsorption isotherms of the three gases in Mg-MOF-74. Finally, the absorption of CO2 and SO2 into three different phosphonium-based Ionic Liquids (ILs) is addressed by using the soft-SAFT equation of state and the COSMO-RS model. From the calculated adsorption/absorption isotherms several properties are obtained, such as the purity in the recovered gas, the working capacity of the materials and their selectivity to capture CO2 in the presence of other contaminant species. The main results obtained from this part of the thesis reveal that the cations of microporous materials are very strong sites of absorption for polar gases (i.e., the Na+ cations in Faujasites or the Mg2+ cations in Mg-MOF-74). This feature makes them very good candidates for CO2 capture, but they can be easily poisoned by other polar gases such as SO2. For this reason, it is highly recommended to desulphurize the flue gas before using any of these adsorbents. Similarly, ILs have higher affinity for SO2 than for CO2. However, the gas/IL interactions are significantly weaker, so they do not become poisoned by SO2. This fact implies that SO2 can be captured and separated from the flue gas by using a phosphonium-based IL. The second topic describes via Molecular Dynamics simulations the interactions of several model oils with different rocks and brines. The obtained insight can be applied in better understanding the interactions of the species present at oil reservoirs, with direct application in enhanced oil recovery processes. To that end, two wettability indicators are monitored to determine the potential recovery of the model oils. First, the oil/water interfacial tension (IFT) under different conditions of temperature, pressure and salinity (i.e., from pure water to 2.0 mol/kg of NaCl or CaCl2). And second, the oil/water/rock contact angle (CA) on calcite (10-14) and kaolinite (001) also as a function of salinity (i.e., from pure water to 2.0 mol/kg of NaCl or CaCl2). The different model oils are built with molecules of different chemical nature representing the Saturate/Aromatic/Resin/Asphaltene (SARA) fractionation model. In a final stage of the doctoral thesis the effect of non-ionic surfactants at the oil/brine IFT is also included. The main results obtained show that the most polar components of oil migrate to the oil/water interface and reduce the IFT. However, the same compounds feel attracted to the rock, who increase the CA and hamper the oil recovery. Some of these interactions are affected by the presence of salt. Specifically, if a water layer is formed between the oil and the rock in a reservoir, electrolytes can diffuse into it and attract the polar components of oil, ultimately increasing the CA. Finally, cations can be attracted to the oil/water interface due to salt/surfactant interactions. Both species interact synergistically to modify their orientation/distribution at the interface and reduce the oil/water IFT.<br>En aquesta tesi doctoral s’han tractat dos temes principals des d’una perspectiva teòrica i computacional: la captura i separació de gasos de post-combustió, i la recuperació millorada de petroli. El primer tema avalua la separació de CO2 utilitzant tres materials diferents. Primer, s’han estudiat diverses zeolites de la família de les Faujasites amb una combinació de teoria del funcional de la densitat (TFD) i mètodes Monte Carlo per entendre els mecanismes d’adsorció separació de CO2 d’una mescla ternària que conté CO2, N2 i O2. Seguidament, s’ha presentat un estudi TFD d’adsorció de CO2, N2 i SO2 en Mg-MOF-74 per determinar les interaccions fonamentals del MOF amb cada gas. Aquesta informació s’ha acoblat a un model d’isoterma de Langmuir per tal de derivar les isotermes d’adsorció macroscòpiques dels tres gasos en Mg-MOF-74. Finalment, s’ha analitzat l’absorció de CO2 i SO2 en tres Líquids Iònics (LIs) basats en fosfoni mitjançant l’equació d’estat soft-SAFT i el model COSMO-RS. D’altra banda, el segon tema descriu les interaccions de diferents models de petroli amb roques i salmorres, via simulacions de Dinàmica Molecular. El coneixement adquirit en aquesta part de la tesi doctoral es pot aplicar directament a la recuperació millorada de petroli i per entendre millor les interaccions de les espècies presents als pous. Amb aquesta finalitat, s’han controlat dos indicadors de la mullabilitat per determinar la recuperació potencial d’aquests models de petroli. Primer la tensió interfacial (TIF) oli/aigua sota diferents condicions de temperatura, pressió i salinitat (des d’aigua pura a 2.0 mol/kg de NaCl o CaCl2). I segon, l’angle de contacte oli/aigua/roca en calcita (10-14) i caolinita (001) en funció de la salinitat (des d’aigua pura a 2.0 mol/kg de NaCl o CaCl2). Els diferents models de petroli s’han construït amb molècules de diferent naturalesa química representant el model de fraccionament Saturat/Aromàtic/Resina/Asfaltè (SARA). En una etapa final de la tesi doctoral s’ha inclòs l’efecte en la TIF induïda pels surfactants no-iònics a la interfase oli/salmorra.

Abstract:
As reserves of conventional crude oil are depleted, there is a growing need to develop unconventional oils such as heavy oil and bitumen from oil sands. In terms of recoverable oil, Canadian oil sands are considered to be the second largest oil reserves in the world. However, the upgrading of bitumen from oil sands to synthetic crude oil (SCO) requires nearly ten times more hydrogen (H<sub>2</sub>) than the conventional crude oils. The current H<sub>2</sub> demand for oil sands operations is met mostly by steam reforming of natural gas. With the future expansion of oil sands operations, the demand of H<sub>2</sub> for oil sand operations is likely to quadruple in the next decade. As natural gas reforming involves significant carbon dioxide (CO<sub>2</sub>) emissions, this sector is likely to be one of the largest emitters of CO<sub>2</sub> in Canada. <br> <br>In the current H<sub>2</sub> plants, CO<sub>2</sub> emissions originate from two sources, the combustion flue gases from the steam reformer furnace and the off-gas from the process (steam reforming and water-gas shift) reactions. The objective of this study is to develop a process that captures CO<sub>2</sub> at minimum energy penalty in typical H<sub>2</sub> plants. <br> <br>The approach is to look at the best operating conditions when considering the H<sub>2</sub> and steam production, CO<sub>2</sub> production and external fuel requirements. The simulation in this study incorporates the kinetics of the steam methane reforming (SMR) and the water gas shift (WGS) reactions. It also includes the integration of CO<sub>2</sub> capture technologies to typical H<sub>2</sub> plants using pressure swing adsorption (PSA) to purify the H<sub>2</sub> product. These typical H<sub>2</sub> plants are the world standard of producing H<sub>2</sub> and are then considered as the base case for this study. The base case is modified to account for the implementation of CO<sub>2</sub> capture technologies. Two capture schemes are tested in this study. The first process scheme is the integration of a monoethanolamine (MEA) CO<sub>2</sub> scrubbing process. The other scheme is the introduction of a cardo polyimide hollow fibre membrane capture process. Both schemes are designed to capture 80% of the CO<sub>2</sub> from the H<sub>2</sub> process at a purity of 98%. <br> <br>The simulation results show that the H<sub>2</sub> plant with the integration of CO<sub>2</sub> capture has to be operated at the lowest steam to carbon (S/C) ratio, highest inlet temperature of the SMR and lowest inlet temperatures for the WGS converters to attain lowest energy penalty. H<sub>2</sub> plant with membrane separation technology requires higher electricity requirement. However, it produces better quality of steam than the H<sub>2</sub> plant with MEA-CO<sub>2</sub> capture process which is used to supply the electricity requirement of the process. Fuel (highvale coal) is burned to supply the additional electricity requirement. The membrane based H<sub>2</sub> plant requires higher additional electricity requirement for most of the operating conditions tested. However, it requires comparable energy penalty than the H<sub>2</sub> plant with MEA-CO<sub>2</sub> capture process when operated at the lowest energy operating conditions at 80% CO<sub>2</sub> recovery. <br> <br>This thesis also investigates the sensitivity of the energy penalty as function of the percent CO<sub>2</sub> recovery. The break-even point is determined at a certain amount of CO<sub>2</sub> recovery where the amount of energy produced is equal to the amount of energy required. This point, where no additional energy is required, is approximately 73% CO<sub>2</sub> recovery for the MEA based capture plant and 57% CO<sub>2</sub> recovery for the membrane based capture plant. <br> <br>The amount of CO<sub>2</sub> emissions at various CO<sub>2</sub> recoveries using the best operating conditions is also presented. The results show that MEA plant has comparable CO<sub>2</sub> emissions to that of the membrane plant at 80% CO<sub>2</sub> recovery. MEA plant is more attractive than membrane plant at lower CO<sub>2</sub> recoveries.

Abstract:
Serious games and its related fields have lately received a lot of interest due to their potential for training and education. Serious games can be defined as (digital) games that are used for reasons other than entertainment. Gamification can be related to serious games and can be defined as the process of game-thinking and game mechanics to engage users and solve problems.The initiator of this project was ABB. ABB delivers a process control system used to control the processes of an oil production facility. One of these processes is separating oil and gas from water. A simulator of this separation process was developed and then implemented into HawkEye, a prototype of the existing process control system. We have worked with ABB to gamify the implemented separation process using different game mechanics to discover whether gamification can be used to improve a process operator&apos;s skills, understanding, and motivation. In a process control system, the process at hand has the highest priority due to its severity, which means that the gamified elements have to be subtle.The implemented separation process was tested on two groups consisting of ten people each, most of them students. The two groups carried out the separation process twice, one time without the gamified elements and one time with the gamified elements. The difference between the two groups was in which order they did the separation process.After the experiment, data was gathered from the implemented system, and also from a survey, a quiz and interviews that we conducted. These data were analysed to determine if the gamified separation process yielded better results than the non-gamified separation process. Results from the experiments showed that there was no improvement in the participants&apos; skill or understanding because of gamification, but that the gamified elements had a positive effect on both groups&apos; motivation.

Abstract:
The increase in greenhouse gas (GHG) concentrations in the atmosphere, as well as the high rate of depletion of hydrocarbon-based resources have become a global concern. A major source of emissions of hydrocarbon vapours occur during loading and offloading operations in crude oil shuttle tanker transportation. The emitted gases have a typical composition of 60 % N2, 10 % CO2, 5% O2, 5 % C3H8, 10% CH4, 5% C2H6 and 5 % higher hydrocarbons. As a result, various methods aimed to add value to GHG to produce valuable fuels and chemical feedstock are being developed. This work incorporates the use of silica, polyurethane/zeolite and y-type zeolite membrane on an alumina support to selectively permeate methane and carbon dioxide from inert gases and higher hydrocarbons. The recovered gas is upgraded by dry reforming reactions employing rhodium/alumina membrane incorporated into a shell and tube reactor. Mixed gas permeation tests have been carried out with the permeate and feed gases sent to the online gas chromatograph (GC) equipped with a mass spectrometry (MS) detector and an automated 6-port gas sampling valve with a 30 mm HP- Plot Q column. The question is what mesoporous membrane can be highly selective for the separation of methane and carbon dioxide from inert gases and higher hydrocarbons, and what is the effect of temperature and feed gas pressure on the conversion of separated gases? Characterisation of the modified membranes was carried out using nitrogen physisorption measurements and showed the hysteresis isotherms corresponding to type IV and V, which is indicative of a mesoporous membrane. The surface area and the pore size were determined using the Barrett, Joyner, Halenda (BJH) desorption method, which showed the silica membrane had a larger surface area (10.69 m2 g-1) compared to zeolite (0.11 m2 g-1) and polyurethane/zeolite membrane (0.31 m2 g-1). Fourier Transform Infrared spectroscopy, Scanning Electron Microscope and Energy Dispersive X-ray Analysis confirmed the asymmetric deposition of silica, polyurethane, rhodium and zeolite crystals in the matrix of the alumina support. Single gas permeation tests showed that the synthesised y-type zeolite membrane at 293 K had a CH4/C3H8 selectivity of 3.11, which is higher than the theoretical value of 1.65. The permeating CH4 and C3H8 flux at 373 K and a pressure of 1 x 105 Pa was 0.31 and 0.11 mol s-1 m-2 respectively proving that zeolite has molecular sieving mechanism for separation of methane and propane. The silica membrane exhibited higher effectiveness for the separation of CO2 than the other membranes. For methane dry reforming using a supported rhodium membrane, an increase of the reaction temperature from 973 K to 1173 K showed an increase in conversion rate of CO2 and CH4 from less than 20% to over 90% while increasing the gas hourly space velocity (GHSV) did not have a noticeable effect. The study revealed the high potential of the zeolite and rhodium membrane for gas separation and dry reforming reactions concept in creating value-added carbon-based products from CO2 and CH4.

O trabalho avaliou o efeito dos dispositivos internos do vaso separador sobre a dinâmica do escoamento no processo de separação gás/óleo. Foi definido uma modelagem matemática com base na dinâmica de fluidos computacional (CFD) do separador horizontal bifásico. Adotou-se a abordagem Euleriana-Euleriana, considerando o modelo de mistura, disponibilizado no software Ansys CFX 15.0. O domínio consiste em um separador horizontal cilíndrico constituído de uma placa porosa que o divide em duas regiões: a região de separação primária, contendo três dispositivos internos (um defletor e duas chicanas) e a região de decantação. Foi gerada uma malha numérica empregando elementos tetraédricos, para a discretização das equações de conservação de massa, momento linear e de turbulência k padrão usando o método dos volumes finitos. Assumiu-se o escoamento em regimes permanente e transiente, isotérmico, com propriedades dos fluidos constantes e das forças interfaciais foram consideradas apenas as forças de arraste. Os resultados dos campos vetoriais de velocidade, assim como a fração volumétrica das fases indicam que a dinâmica do escoamento é fortemente dependente dos dispositivos internos. Na região de separação primária observou-se um alto nível de mistura causada pela turbulência gerada pelo impacto dos fluidos sobre a placa defletora posicionada imediatamente após a seção de entrada. A placa porosa possibilitou uma redução da turbulência dos fluidos, causada pela resistência do meio poroso ao escoamento.<br>The separators are equipments used in the primary processing of the petroleum industry to separate the multiphase mixture from the producing wells. The work evaluated the effect of the internal devices of the separator vessel on the flow dynamics in the gas/oil separation process. A mathematical model was defined based on computational fluid dynamics (CFD) of the horizontal two-phase separator. The Eulerian-Eulerian approach was adopted, considering the mixture model, available in Ansys CFX 15.0 software. The domain consists of a horizontal cylindrical separator consisting of a porous plate that divides it in to two regions: the primary separation, containing three internal devices (one deflector plate and two baffles) and the settling region. A numerical grid was generated employing tetrahedral elements, for the discretization of the mass conservation, linear momentum and k standard turbulence equations using the finite volume method. Isothermal flow with constant fluid properties in both steady state and transient regimes were assumed, and, from the interfacial forces, only the drag forces were considered. The velocity vector field results as well as the volumetric fraction of the phases indicate that the flow dynamics are strongly dependent on the internal devices. In the primary separation region, a high-level of mixing was observed due to the turbulence generated by the impact of the fluids on a deflector plate positioned immediately after the inlet section. The porous plate allowed a reduction of the turbulence of the fluids, caused by the resistance of the porous medium to the flow.

Abstract:
A system able to simultaneously separate and pump a gas-liquid mixture was developed.<p>It works efficiently and can be used in many applications (nuclear power plants,<p>pulp and paper processing, petroleum extraction, etc.). However, this pump and separator<p>system (PASS) was especially designed to handle air-oil mixture generated in<p>aero-engine lubrication systems. The PASS combines three important functions of the<p>scavenge part of the lubrication system: the deaeration and deoiling of the air-oil mixture<p>generated in the bearing and gearbox sumps and the pumping of the oil towards<p>the tank. These are critical functions for the engine. Indeed, a poor deoiling efficiency<p>leads to a high oil consumption. This reduces the flight endurance, increases the size<p>and weight of the oil tank and has a negative impact on the environment. Poor deaeration<p>and pumping characteristics lead to problems in the cooling and the lubrication of<p>the engine bearings.<p><p>Integrating a PASS into the lubrication system allows considerable improvements<p>(and simplification) to the lubrication system architecture. An important number of<p>components are suppressed: the vent lines, the deoiler, the cyclone deaerator and the<p>scavenge pumps. This reduces the size and the weight of the lubrication system and<p>increases its reliability. Furthermore, an important part of this PhD thesis focuses on<p>reducing the oil consumption in the PASS. This improves the flight endurance, reduces<p>engine maintenance and working costs and is profitable to the environment.<p><p>In addition to the development of an advanced PASS design system, the objective of<p>this thesis was to obtain a good understanding of the separation processes occurring in<p>the PASS and to develop theoretical models able to predict the separation performance<p>for every working condition encountered in a typical aircraft flight. To achieve this<p>goal, three main tasks were performed: the development of different two-phase measurement<p>systems, the experimental tests of four different PASS architectures and the<p>theoretical development (after an extensive literature review) of correlations predicting<p>the performance of the PASS in function of the working conditions. Five specific aspects<p>of the PASS were studied: the inlet flow, the deoiling efficiency, the deaeration efficiency,<p>the pumping efficiency and the pressure drop. Finally, the models that have been developed<p>with the help of the measurement systems and of the experiments have been<p>integrated in a complete model of the lubrication system (under the EcosimPro modelling<p>environment). This helps to predict real in flight PASS working conditions and<p>performance. Indeed, the PASS is very sensitive to the engine working conditions and<p>an optimisation of the prototype size and performance is only feasible with an accurate<p>knowledge of these working conditions and a complete lubrication system model.<p>Finally, with the results of this PhD thesis, a new PASS design, optimised for different<p>aero-engine lubrication systems, is presented.<br>Doctorat en Sciences de l'ingénieur<br>info:eu-repo/semantics/nonPublished

Abstract:
Turkey occupies a strategic position in today's world: culturally, historically, and geographically, it is the link between Islam and Western democracy, between Europe and the Middle East. The only predominantly Muslim nation to be a member of NATO and an ally of Israel, Turkey straddles both Europe and Asia. And it boasts an economy larger than any of the states that have joined the EU in recent years--Istanbul alone has a bigger economy than that of Hungary or the Czech Republic--with pipelines that carry much of the world's oil and gas. Andrew Finkel has spent twenty years in Turkey writing about the country for a number of leading news media such as The Economist and Time magazine. In this concise book, Finkel unravels Turkey's complexities, setting them against the historical background of the Ottoman Empire, the secular nationalist revolution led by Kemal Atatürk, and repeated political interventions by the military, which sees itself as the guardian of Atatürk's legacy. Finkel reveals a nation full of surprises. Turkey's labyrinthine politics often lead to such unexpected outcomes as leaders of the untra-nationalist party starting on the road to EU membership by voting to scrap the death penalty--which also meant giving a reprieve to the convicted leader of the Kurdish separatist movement. And where else but in Turkey, Finkel writes, would secularist liberals have supported a prime minister who was once jailed for promoting religious extremism? From the Kurdish question to economic policy, from Turkey's role in Iraq to its quest for EU membership, Finkel illuminates the past and present of this unique, and uniquely consequential, country.
