Download or read book Processing of Heavy Crude Oils written by Ramasamy Marappa Gounder and published by Intechopen. This book was released on 2019 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unconventional heavy crude oils are replacing the conventional light crude oils slowly but steadily as a major energy source. Heavy crude oils are cheaper and present an opportunity to the refiners to process them with higher profit margins. However, the unfavourable characteristics of heavy crude oils such as high viscosity, low API gravity, low H/C ratio, chemical complexity with high asphaltenes content, high acidity, high sulfur and increased level of metal and heteroatom impurities impede extraction, pumping, transportation and processing. Very poor mobility of the heavy oils, due to very high viscosities, significantly affects production and transportation. Techniques for viscosity reduction, drag reduction and in-situ upgrading of the crude oil to improve the flow characteristics in pipelines are presented in this book. The heavier and complex molecules of asphaltenes with low H/C ratios present many technological challenges during the refining of the crude oil, such as heavy coking on catalysts. Hydrogen addition and carbon removal are the two approaches used to improve the recovery of value-added products such as gasoline and diesel. In addition, the heavy crude oil needs pre-treatment to remove the high levels of impurities before the crude oil can be refined. This book introduces the major challenges and some of the methods to overcome them.
Download or read book Foreign Direct Investment in Latin America and the Caribbean 2010 written by United Nations and published by UN. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2010, the Latin American and Caribbean region showed great resilience to the international financial crisis and became the world region with the fastest-growing flows of both inward and outward foreign direct investment (FDI). The upswing in FDI in the region has occurred in a context in which developing countries in general have taken on a greater share in both inward and outward FDI flows. This briefing paper is divided into five sections. The first offers a regional overview of FDI in 2010. The second examines FDI trends in Central America, Panama and the Dominican Republic. The third describes the presence China is beginning to build up as an investor in the region. Lastly, the fourth and fifth sections analyze the main foreign investments and business strategies in the telecommunications and software sectors, respectively.

Download or read book Lanzarote and Chinijo Islands Geopark From Earth to Space written by Elena Mateo and published by Springer. This book was released on 2019-04-25 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises a selection of papers describing the main features of the Lanzarote and Chinijo Islands Geopark (Canary Archipelago, Spain). Of all the Global Geoparks worldwide, it is the only one that has officially evaluated and characterized specific areas as analogues for the geological and astrobiological exploration of Mars. The identification and characterization of terrestrial sites that can be used as planetary analogues are currently considered vital study areas of planetary geology and astrobiology. Written by experts in the various fields, this multidisciplinary book is a unique resource for graduate students and professionals alike.

Download or read book Gold metallogeny and exploration written by R. P. Foster and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses ofall major aspects ofgold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.
Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Available in PDF, EPUB and Kindle. Book excerpt: Containing an in-depth study of the emerging theory and core of ecological law, this book insightfully proposes a 'lens of ecological law' through which the disparity between current laws and ecological law can be assessed. The lens consists of three principles: ecocentrism, ecological primacy and ecological justice. These principles are used within the book to explore and analyse the challenges and opportunities related to the transition to ecological law and to examine three key mining case studies.
