Tianjin suburbs subsidence monitoring with L- and X-band multi-temporal InSAR data.

January 2013 (has links)
天津是中國遭受地面沉降最嚴重的城市之一。由於經濟與城市化的快速發展,新的沉降中心陸續出現在天津的郊區城鎮。本文結合L-和X-波段合成孔徑雷達(Synthetic Aperture Radar, SAR)資料,利用雷達干涉測量(SAR Interferometry, InSAR)時間序列分析,旨在加強天津郊區的沉降監測能力。先進的基於SAR資料的遙感技術,永久散射體干涉測量(Permanent Scatterers, PS)技術被證明是一種有效的,大範圍的,低成本的沉降監測手段。 / 工作在X波段(波長為3.1cm)的TerraSAR (TSX)衛星可以提供新一代具有高解析度(1米)和短重放週期(11天)的SAR資料,從而能夠更快的獲取適用於干涉的時間序列的資料,並且適用於單個建築物的沉降觀測。然而,利用X-波段在森林或植被覆蓋區域並不能得到有效資訊。ALOS衛星的SAR感測器工作在L波段,由於波長更長(波長為23cm),穿透力更強,所以在植被覆蓋區域也具有良好的相干性。但是ALOS衛星的SAR資料解析度更低(7米),重放週期更長(46天)。從這兩個波段的資料特徵來看,他們可以被認為是互補的。所以,結合這兩個波段的資料可以增強沉降監測的能力和提供更為可靠的結果。儘管ALOS衛星於2011年4月22日停止了工作,我們的研究結果仍然可以為結合不同波段的SAR資料進行沉降監測提供普遍適用的結論,並為以後的研究工作提供參考。 / 在研究中,我們提出了結合L和X波段的InSAR時間序列分析策略。此策略不僅可以作為X波段資料最優化獲取方案,而且可以成為快速,高精度,低成本,多級,大範圍監測策略。 / 其次,我們基於多時序SAR資料,利用PS和准PS(Quasi-PS, QPS)技術進行了L波段與X波段的沉降監測能力探尋。L波段和X波段的時間序列分析所得到的沉降模式有很好的吻合性,都監測出三個主要的沉降中心,其中包括一個新近發現的沉降中心位於南河鎮。 / X波段的PS分析結果顯示出高密度的PS點,證實了它可以用於同時監測星狀分佈的多個城鎮。結果也表明了高解析度TSX資料可以監測到線狀地物如鐵路,高速公路以及電力線的細節資訊和沉降資訊,這些可以成為高解析度PS技術在中國的重要應用。 / 除此之外,我們利用水準資料驗證了L和X波段的處理結果,並且對地面沉降的過程進行了研究。由於水準資料和PS監測結果在時間和空間維上的採樣差別很大,所以我們對這兩者比較所具有的不確定性進行了詳細分析。結果表明了這兩種監測資料具有很好的一致性。 / 最後,我們發現在天津抽取地下水是引起地面沉降的一個主要原因。根據PS結果和地質資料,我們發現地質因素可能是另一個用於解釋沉降中心位置和形狀的原因。 / The aim of this dissertation is to enhance the capability of monitoring subsidence in Tianjin suburbs by combining L- and X-band Synthetic Aperture Radar (SAR) data with Interferometry (InSAR) time series analysis. Tianjin is located in one of the major subsidence regions in China and several new subsiding centers have been found in the suburbs of Tianjin. Advanced remote sensing technique, Permanent Scatterers (PS) based on SAR data has been found to be a feasible way to detect and monitor wide area ground subsidence at a low cost. / TerraSAR X-band (TSX) of short wavelength (3.1 cm) provides new generation SAR data with high spatial resolution of 1 m and short revisit period of 11 days. It maintains the capability to fast build up interferometric stack, and to measure the subsidence of individual features, while almost no information can be detected with X-band in the forested and vegetated areas. ALOS L-band signal of longer wavelength (23cm) penetrates deeper into the vegetation cover and depicts higher coherence over non-urban areas, while the spatial resolution is relatively lower (7m) and revisit time is longer (46 days). The characteristics of these two bands can be regarded as complementary. Combining L- and X-band can enhance abilities of subsidence monitoring and provide more reliable results. Although ALOS died on April 22, 2011, this research work will provide general answers for combining different bands of SAR data to monitor subsidence, and give suggestions for future research work. / In this research work, we have developed the strategy of combining L- and X-band with InSAR time series analysis. This strategy can not only be an optimized X-band acquisition plan, but also be a multi-level wide area monitoring strategy of subsidence with fast extraction, high precision and low cost. / Moreover, with multi-temporal SAR data, we also investigate monitoring abilities of L- and X-band by exploring PS and Quasi-PS (QPS) techniques. The subsidence patterns derived from L- and X-band InSAR time series analysis are observed to have a good agreement. Three severe land subsidence zones were detected, containing one newly discovered subsiding center located in Nanhe Town. / The X-band PS analysis shows high density of PS points and confirms its strong ability for simultaneously monitoring subsidence over star-like-distributed multiple towns. The results also demonstrate that linear constructions such as railways, highways and power lines can be detected in detail with high resolution TSX SAR data and indicates the deformation monitoring capability for large-scale man-made linear features which is a key application in China. / Furthermore, L- and X-band results were independently validated with leveling data and ground motion processes were studied. The uncertainties were comprehensively analyzed between PS results and ground leveling data, whose densities are very different in both spatial and temporal domains. The overall results show a good agreement with each other. / Finally, we find that underground water extraction is one of the major reasons for ground subsidence in Tianjin. In addition, with the integrated analysis of the PS results and the geological data, we found that lithological characteristics may be another important reason to explain location and shape of the subsiding centers. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Luo, Qingli. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 103-112). / Abstract also in Chinese. / Abstract --- p.I / TABLE OF CONTENT --- p.VI / List of Figures --- p.VIII / List of Tables --- p.XI / List of abbreviations --- p.XII / ACKNOWLEDGEMENT --- p.XIV / Chapter 1 --- INTRODUCTION --- p.1 / Chapter 1.1 --- Thesis contributions --- p.6 / Chapter 1.2 --- Thesis structure --- p.7 / Chapter 2 --- BACKGROUND --- p.9 / Chapter 2.1 --- Synthetic Aperture Radar (SAR) --- p.9 / Chapter 2.1.1 --- SAR imaging geometry --- p.9 / Chapter 2.1.2 --- SAR satellites --- p.10 / Chapter 2.2 --- Synthetic Aperture Radar Interferometry (InSAR) --- p.13 / Chapter 2.2.1 --- Introduction --- p.13 / Chapter 2.2.2 --- Principles of InSAR --- p.13 / Chapter 2.3 --- Differential Synthetic Aperture Radar Interferometry (D-InSAR) --- p.18 / Chapter 2.3.1 --- D-InSAR principle --- p.18 / Chapter 2.3.2 --- The advantages and Limits of interferometric measurements --- p.21 / Chapter 2.4.3 --- The development of PS technique --- p.22 / Chapter 2.4 --- Persistent Scatterers Interferometry (PSI) --- p.24 / Chapter 2.4.1 --- Permanent Scatterers (PS) Technique and Advantages --- p.24 / Chapter 2.4.2 --- Principle of PS technique --- p.26 / Chapter 2.5 --- QPS (Quasi-PS) Interferometry --- p.28 / Chapter 3 --- MULTI IMAGES INSAR ANALYSIS OF TIANJIN --- p.31 / Chapter 3.1 --- Introduction --- p.32 / Chapter 3.2 --- Study area and SAR data --- p.34 / Chapter 3.3 --- X-band optimized acquisition planning combing with L-band --- p.38 / Chapter 3.3.1 --- The strategy --- p.38 / Chapter 3.3.2 --- Experimental results and analyzes --- p.40 / Chapter 3.4 --- Estimating deformation maps with L- and X-band --- p.45 / Chapter 3.4.1 --- Monitoring subsidence over multiple towns and large man-made linear features with X-band --- p.45 / Chapter 3.4.2 --- The L-band QPS Results --- p.56 / Chapter 3.5 --- Conclusions --- p.58 / Chapter 4 --- VALIDATION AND INTERPRETAION --- p.61 / Chapter 4.1 --- Introduction --- p.61 / Chapter 4.2 --- Validation --- p.61 / Chapter 4.2.1 --- Leveling data --- p.61 / Chapter 4.2.2 --- Uncertainties analysis --- p.64 / Chapter 4.2.3 --- Average velocity comparison --- p.66 / Chapter 4.2.4 --- Annual displacement comparison --- p.68 / Chapter 4.2.5 --- Deformation time series: InSAR results and leveling --- p.70 / Chapter 4.2.6 --- Average velocity map comparison between InSAR results and leveling --- p.71 / Chapter 4.2.7 --- Displacement comparison between InSAR results and GNSS data --- p.73 / Chapter 4.2.8 --- Average velocity comparison between ALOS results and leveling --- p.73 / Chapter 4.3 --- Geological Interpretation --- p.74 / Chapter 4.4 --- Field survey --- p.77 / Chapter 4.5 --- QPS points analysis with aerophotograph --- p.81 / Chapter 4.6 --- Conclusions --- p.84 / Chapter 5 --- VALIDATION ALONG RAILWAY --- p.87 / Chapter 5.1 --- Introduction --- p.87 / Chapter 5.2 --- Study area --- p.87 / Chapter 5.3 --- The validation plan --- p.87 / Chapter 5.4 --- Validation with leveling data --- p.89 / Chapter 5.4.1 --- Leveling data --- p.89 / Chapter 5.4.2 --- The average subsidence rate comparison --- p.91 / Chapter 5.4.3 --- The displacement comparison --- p.95 / Chapter 5.5 --- Conclusions --- p.97 / Chapter 6 --- SUMMARY --- p.98 / The Publications --- p.102 / REFERENCES --- p.103

De l'ancienne concession italienne de Tianjin à l'I-Style Town : enjeux et processus de la patrimonialisation et du développement touristique / From the former Italian concession of Tianjin to the I-Style Town : stakes and processes of heritagization and tourism development

Lu, Yue 22 November 2017 (has links)
Le paysage des quartiers de style occidental en Chine a été bouleversé durant les deux dernières décennies par deux dynamiques majeures, la patrimonialisation et la touristification, particulièrement dans la ville de Tianjin, où celles‑ci se traduisent par un processus de thématisation spatiale. A partir de ce constat, cette thèse se penche sur le rôle du patrimoine de style occidental dans le tourisme urbain en postulant que les dynamiques du patrimoine et du tourisme se croisent pour produire un espace original thématique dans une ville contemporaine chinoise. En s’appuyant sur le cas de l’ancienne concession italienne à Tianjin, ce travail propose une triple lecture de cet espace. Le premier axe cherche à contextualiser ces questionnements de patrimoine de style occidental en Chine en construisant un cadre théorique et méthodologique. La deuxième lecture analyse les conditions de production de l’espace à thème italien, en montrant que, tant sur le plan matériel que sur le plan symbolique, la mise en tourisme et la thématisation du quartier italien est fondée sur la présence du cadre patrimonial. Enfin, la troisième lecture s’attache à comprendre les modalités de consommation développées dans cet espace en mettant l’accent sur les ressorts des pratiques et le plan expérientiel des visiteurs. Ainsi, cette thèse appuie l’analyse sur la réinterprétation des territoires (semi‑) colonisés par/pour des pratiques touristiques, et les fondements socioculturels de celles‑ci, afin de mieux comprendre la validité des théories occidentales dans le contexte chinois et l’idéologie contemporaine de la société chinoise envers cette tendance. / The landscape of western‑style neighbourhoods in China has been shaken over the last two decades by two major dynamics, heritagization and touristification, especially in the city of Tianjin, where they are translated into a process of spatial theming. Based on this observation, this thesis examines the role of Western‑style heritage in the urban tourism implementation, considering that the dynamics of heritage and tourism intersect to produce an original themed space in a contemporary Chinese city. Taking the former Italian concession in Tianjin as case study, this work offers a triple reading of this space. The first is to contextualise these questions of Western‑style heritage in China and to construct a theoretical and methodological framework. The second reading level analyses the production conditions of the Italian themed space, showing that both on a material and a symbolic level, the touristification and the theming of the Italian area is based on the presence of its heritage backdrop. The third reading focuses on understanding the consumer patterns developed in this area, focusing on the practices and experiences of visitors. Thus, this thesis focuses on the reinterpretation of (semi‑)colonised territories by/for tourism activities and their sociocultural foundations with the aim to better understand the validity of Western theories in a Chinese context, and contemporary ideology of Chinese society regarding to this trend.

Les Hautes Études Industrielles et Commerciales de Tianjin (Tianjin Gongshang xueyuan 天津⼯工商学院), 1923-1951 : un exemple de l'action éducative des Jésuites en Chine / The Tianjin «Hautes Etudes Industrielles et Commerciales» Institute 天津工商学院[Tianjin Gongshang xueyuan], 1923-1951 : an example of the Jesuit educational action in China

Dehoux-Dutilleux, Corinne 15 June 2018 (has links)
L’Institut des Hautes Études Industrielles et Commerciales de Chine fut fondé par les Jésuites à Tianjin en 1921. Cette école technique supérieure, alors qu’on assiste à une prolifération étonnante d’établissements d’enseignement secondaire ou supérieur, aussi bien nationales qu’anglaises ou américaines (protestantes), répond aux besoins du développement industriel de la région (Chine du Nord). Ainsi en jugèrent à la fois les autorités françaises et l’Église catholique. Ce sont les Jésuites de la Mission de Champagne qui sont chargés de ce nouvel établissement, et qui s’en occupent jusqu’à sa fermeture. Ils fondent en Chine deux établissements d’enseignement supérieur : la célèbre université «L’Aurore », mise sur pied en 1903 par le Père Joseph Ma Xiangbo (1840-1939) à Zikawei, près de Shanghai (震旦学院 Zhendan Xueyuan, Aurora University) ; l’université Furen (辅仁大学 Furen ), créée à Pékin en 1925 ; et donc l’Institut des Hautes Études Industrielles et Commerciales à Tianjin, qui nous occupe ici. L’Institut des Hautes Études Industrielles et Commerciales à Tianjin est fondé sous le nom d’Institut du Sacré-Cœur, dans la province du Zhili (直隶), actuel Hebei. Il changera de nom par la suite, devenant Jingu daxue (津沽大学) (Université Tsinkou) puis Gong Shang College. Après un examen d’admission, le 15 septembre 1923, les 35 premiers élèves font leur rentrée à l’Institut. En 1949, quelques jours seulement après la « libération » de Tianjin par les communistes, le Père Bonningue (1908-1997), figure emblématique des derniers temps de la maison, prend la direction de l’Institut des Hautes Études de Tianjin. C’est sous son rectorat, qui ne dure que deux ans, que l’École est progressivement « soviétisée », jusqu’à sa totale prise en main par l’administration communiste, qui la convertira en un établissement public. Les Jésuites, dont certains sont incarcérés et soumis à la torture, seront chassés de Chine à partir de 1952. Quel a été l’apport des jésuites de Tianjin dans la formation des élites chinoises ? Quelle a été leur influence morale et religieuse sur les jeunes gens formés par eux ? Quelle est la particularité jésuite dans la création et le maintien, dans des circonstances inédites, de cette école ? / The Tianjin «Hautes Etudes Industrielles et Commerciales» Institute was founded in Tianjin, China by the Jesuits in 1921. While a surprising proliferation of secondary schools and colleges, either national, English or American (being protestant indeed) were expected, French authorities and the catholic Church thought that this superior technical school was in fact an answer to the needs of the industrial development of the region (North China). The Jesuits from the Mission of Champagne were the ones that became in charge of this new school and remained at its head until it closed. The French Jesuits understood that the Chinese elite, more sensitive to Western knowledge than to the Christian dogma, was the key to access to the people. They founded two institutions of higher education in China : the Aurora University (震旦学院 Zhendan Xueyuan) in 1903 by Father Joseph Ma Xiangbo (1840-1939) in Zikawei, near Shanghai and the « Institut des Hautes Études Industrielles et Commerciales » in Tianjin, our present study. The « Institut des Hautes Études Industrielles et Commerciales » of Tianjin was fonded in 1921, on the name of « Institut du Sacré-Cœur », in the Zhili (直隶) province, present Hebei. First called Gong Shang College, it will change name to Jingu daxue (津沽大学), Tsinkou University. On September 15th 1923, after being admitted at an entrance exam, the first 35 pupils started school at the Institute which functioned in its original form until the late1940’s. In 1949, only a few days after Tianjin was freed, which happened to be the greatest liberation campaign led by the Communists, Father Bonningue (1908 - 1997), who was the emblematic figure of the last hours in the House, took the Tianjin «Hautes Études» Institute into control. It was under his 2-year rectorship that the school turned soviet little by little, until it became totally ruled by the communist administration and changed into a state school in the end. The Jesuits, among whom some were jailed and tortured, were expelled from China from 1952 onwards. What have the Jesuits from Tianjin brought to the actual Chinese upperclass society? What has their moral and religious influence been on the young pupils who had been taught? What is the Jesuit distinguishing feature in the creation and support of the school which have gone through difficult times in China.

Treatment Technology for VOC Emissions from Oil Refineries : Case study of measures taken to minimize VOC emissions at Swedish petrochemical companies to be appiled at Chineses Refineries

Odén, Hanna January 2010 (has links)
The aim of this thesis is to give suggestions on what measures to take to improve the VOC emission situation in refineries in Tianjin, China, through existing technologies in refineries in Sweden. This has been done by identifying the main places of leakage in oil refineries in Sweden, identifying what VOC compounds are emitted from the plants and the amounts emitted, mapping out different measures taken by oil refineries in Sweden to minimize VOC emissions, evaluating the different measures and suggesting how to move forward with VOC control in Tianjin. Six case studies have been done in Sweden; at Preemraff Lysekil, Shell refinery in Gothenburg, Berg depot Statoil Sweden situated in Nacka, Nynas refinery situated in Nynäshamn, Scandinavian Tank Storage situated in Torshamnen and Oxelösund harbor. Two case studies at Chinese refineries were made, PetroChina Dagang Petrohemical Company and China Petroleum and Chemical Corporation, Sinopec, Tianjin Branch, both situated in Tianjin Binhai New Area. Since the data retrieved from the Chinese refineries is insufficient to make a qualitative evaluation of the state of their VOC treatment it is not possible to propose measures for these two refineries. Instead this evaluation is focused on general problems and solutions at refineries and gives an idea of what can be done to improve the VOC emission situation at refineries. The report contains an evaluation of internal measures and technical solutions at Swedish refineries and other petrochemical companies. The evaluation is focused as much as possible on the Chinese situation. The technologies have been evaluated from an environmental, technical and economical point of view. This has resulted in recommendations for refineries that wish to enhance their VOC control. / Detta examensarbete har gjorts som en avslutande del i utbildningen Civilingenjör i Kemiteknik vid Kungliga Tekniska högskolan, Stockholm. Idén för arbetet introducerades av Östen Ekengren, IVL Svenska Miljöinstitutet, och har utförts vid IVL:s kontor i Stockholm. Den har handletts från Institutionen för Industriell Ekologi, KTH. Oljeraffinaderier släpper ut stora mängder VOC. På grund av den stora produktionsskalan och fabriksområdets omfattning är det svårt att veta hur mycket och vad som släpps ut. Lättflyktiga organiska ämnen (Volatile organic compounds, VOC) är organiska föreningar som har ett tillräckligt högt ångtrycker för att förångas under normala förhållanden. Stora mängder VOC läcker från oljeraffinaderier varje år. Tianjin är en industristad med stora investeringar. På grund av den stora industriella aktiviteten i området är VOC-problemen stora. En av de stora utsläppsbovarna är den petrokemiska industrin. Tianjin Academy of Environmental Science (TAES) har frågat efter Svensk teknik att minimera VOC-utsläpp från petrokemisk industri. Målet med detta examensarbete är att ge förslag på vilka åtgärder som kan tas för att förbättra VOC-utsläppssituationen i raffinaderier i Kina genom befintlig teknik på Svenska raffinaderier. Detta har gjorts genom följande steg: Identifiera de största utsläppsområdena på oljeraffinaderier i Sverige Identifiera vilka VOC-föreningar som emitteras från raffinaderierna samt i vilken mängd. Kartlägga olika åtgärder vid oljeraffinaderier i Sverige och i Tianjin, Kina för VOC-utsläpp. Utvärdera de olika åtgärderna och föreslå hur man kan gå vidare med VOC-kontroll i Kina. Sex fallstudier har genomförts i Sverige; Preemraff Lysekil, Shell raffinaderi i Göteborg, Bergs depot Statoil Sweden i Nacka, Nynas refinery i Nynäshamn, Scandinavian Tank Storage i Torshmnen och Oxelösunds hamn, Oxelösund. Två fallstudier har genomförts vid Kinesiska raffinaderier; PetroChina Dagang Petrochemical Comapany och China Petroleum and Chemical Corporation, Sinopec, Tianjin Branch, båda placerade i Tianjin Binhai New Area. Eftersom otillräcklig data från de Kinesiska raffinaderierna har gjort det svårt att göra en kvalitativ utvärdering av hur långt de kommit i VOC-arbetet har det inte varit möjligt att föreslå åtgärder för dessa två raffinaderier specifikt. Istället har utvärderingen fokuserats på generella problem och lösningar vid raffinaderier och att ge en ide om vad som kan göras för att förbättra VOC-utsläppssituationen vid raffinaderier. VOC från oljeraffinaderier med traditionell aktivitet består i huvudsak av alkaner, alkener och aromater där alkaner utgör den största delen. Alla dessa tre grupper förekommer naturligt i råolja. Vilka föreningar som förekommer i VOC-plymen från en fabriksanläggning beror på vilken råolja som används, hur processen ser ut och vilka produkter som produceras. Sammansättningen av VOC-plymen varierar därför från raffinaderi till raffinaderi. De största emissionskällorna vid raffinaderier som producerar i första hand bensin och diesel är tankparkerna, speciellt under fyllning. Tankparker som innehåller råolja utgör den största emissionspunkten vid dessa raffinaderier. Den näst största källan är processområdet. Detta medför att tankparker och processområde är de områden där störst fokus på minimering skall ligga för raffinaderier med samma typ av verksamhet. Produktionen vid Nynas Refinery kräver en annan råolja Här är det processen som utgör den största utsläppskällan tillsammans med vattenrening. Uppvärmda bitumencisterner utan rening utgör också en stor utsläppspunkt. Eftersom processområdet och tankparkerna har många potentiella läckpunkter är det primära sättet att minimera VOC-utsläpp tätning och underhåll på hela fabriksområdet. Införandet av rutiner för detta har visat sig mycket effektivt speciellt vid Shell raffinaderi. En annan idé skulle kunna vara att inkludera VOC-utsläppsmätning i on-line system för produktkvalitet. Detta skulle medföra ett inbyggt VOC-kontrollsysem. Detta har inte gjorts än men det kan vara värt att ta en närmare titt på. Kina har stort fokus på luktkontroll. Detta är bara en liten del av VOC-problemet. Metan utgör en stor del av utsläppen från råoljecisterner, vilka är vanliga luktbovar. För att eliminera lukt är adsorbtion med aktivt kol effektivt. Filtret fångar däremot inte kortare kolkedjor som metan och etan. För att eliminera dessa är förbränning den enda lösningen. Ingen luktsanerningsmetod som presenteras i denna rapport genererar någon vinst för företagen. Gasåterföringsanläggningar (VRU) har visats vara en gynnsam metod för att behandla emissioner vid tankning. En snabb överslagsräkning baserat på den återförda mängden bensin och diesel vid Preemraff Lysekil 2008 ger en vinst på 0,9 – 1,3 miljoner Euro/år. En stor andel VOC förbränns i fackla på raffinaderier. Denna gas skulle kunna användas som bränngas eller för energiåtervinning. Penningvärdet på energin i gasen som facklas är stor. Genom att installera en kompressor kan gas som skulle facklas användas som bränngas i raffinaderierna istället. Båda de studerade raffinaderierna i Kina angav fackling som den primära VOC-åtgärden. Man kan därmed anta att stora mängder gas facklas där. Detta visar att det finns mycket att tjäna på att hitta alternativa sätt att använda gasen. Flyktiga utsläpp är en stor del av VOC-källorna vid oljeraffinaderier. Utsläppunkterna beror på typ av råolja, process och produkter. Varje raffinaderi ar unikt och måste därför mäta sin a utsläpp. Vid mätning av ett helt fabriksområde med Solar Occulation Flux-metoden, som är en on-lineteknik som mäter VOC-utsläpp i from av alkaner, fås en bild av totala utsläppen från hela fabriken. Detta är till stor hjälp vid identifiering av problemområden och behandling av dessa. När VOC-behandling skall påbörjas vid ett raffinaderi rekommenderas följande: Mätning av VOC över hela raffinaderiområdetAnvända on-lineteknik, så som SOF Identifiera sammansättning av plymen genom kanisterprov etc. Läcksökning / Underhåll Om följande tekniska lösningar går att applicera vid raffinaderiet föreslås det att de prioriteras. Införa VRU-anläggning Energiåtervinning (minimerad fackling) Införa kommunicerande kärl För fortsatt arbete rekommenderas följande. Undersöka om det finns intresse och möjlighet att införa on-line VOC-konrollsystem eller on-line konstrollsystem för produktkvalitet. Är det tekniskt möjligt och ekonomiskt hållbart? För att kunna utvärdera miljöpåverkan av NMVOC från oljeraffinaderier har en studie av effekterna från emissionerna från Preemraff Lysekil och Shell Göteborg gjorts genom att använda karakteriseringsdata från databaserna CLM2001 och EDIP97. Detta resulterade i ett värde som ger hur många gånger fler de två raffinaderierna per ton satsad råolja bidrar till ozonformationspotentialen och globala uppvärmningspotentialen i förhållande till årspersonsekvivalenten (vad en normalperson bidrar med per år). Det visade sig att de bidrar med mycket mindre än årspersonsekvialenten per ton råolja, 0,03 gåner för Preemraff och 0,02 gånger för Shell. Men med antalet ton råolja som processas per år i åtanke så blir oljeraffinaderierna en stor källa till miljöpåverkan. Toxicitetsvärdena visade att Shell hade mycket större andel toxiska utsläpp än Preemraff. I förbränning, som fackling, så förbränns VOC till CO2. Detta medför att VOC har en sekundär GWP. Om hänsyn tas till detta kan man se att den totala GWP av VOC främst utgörs av den sekundära effekten genom fackling. Denna utvärdering visar att miljöpåverkan är olika för olika raffinaderier, även de med samma typ av verksamhet.

Modern transformation of the Huizhou merchant : Wu Jim-pah (1850-1927) the Mandarin-capitalist in late Qing Tianjin

Hui, Ching, 許楨 January 2011 (has links)
Contrary to the significance that HSBC and its comprador office made on the modernisation in China at the turn of the 19th and the 20th Century, studies about the Bank’s expansion in the Beijing-Tianjin area were exceptionally limited. In this research, the importance of HSBC’s expansion to North China in the 1880s will be primarily examined by the Bank and its comprador office’s roles in the railways development in North China. During this process, Wu Jim-pah, as the first comprador of HSBC in Tianjin, offered significant aids in establishing HSBC’s collaboration with the Qing Court and the influential Bei-yang Ministry under Li Hong-zhang’s administration. This research is going to examine Wu Jim-pah’s career and personal development in late Qing Huizhou, Suzhou, Shanghai, Tianjin and Beijing, so as to answer a series of questions related to China’s social-economic reforms and its earliest capitalists’ formation at the turn of the centuries. Moreover, acts as the first academic study focusing on Wu Jim-pah’s participation in the early modernisation projects of late Qing China, this research put the collection and classification of historical materials in the central place. The findings of primary resources from the archives in China and overseas, namely, the Institute of History and Philology of Academia Sinica in Taipei, the National Library of China, the Shanghai Library, the Southwest Jiao-tong University, the Tianjin Academy of Social Sciences (TASS), the HSBC Group Archives, London School of Oriental and African Studies (SOAS), as well as the Public Record Office at Kew, London, could be regarded as the most valuable part of this research. / published_or_final_version / Humanities and Social Sciences / Doctoral / Doctor of Philosophy
