[Edit] Tabieihalmassadr depletion of natural resources: is a set of materials and energy in the environment. Include sources of natural geological sources, ie sources of origin Gioluigi can be extracted from the earth, including:
A forest in California (USA) forests Tabieihmassadr of the most important sources of energy such as oil, coal and oil shale … And others.
XXXXls such as iron, copper, aluminum, lead, zinc, gold, silver and others.
Industrial rocks and include sand, gravel, limestone, granite, gypsum … And others. In addition to groundwater as an important source of life.
Most of the geological sources are the sources of non-renewable (Nonrenewable resources); as the rate of consumption exceeds the rate of formation, with the exception of groundwater for the possibility of recurrence of rain water, and XXXXls are being recycled (Recycling) which can be re-manufactured (industrially renewed). In addition to geothermal energy as a renewable source of energy. And the intervention of these sources in all types of industry that you know, from the tiles and ending with medicine, Registry, lead you use, consists of the sources of geological, electrical appliances, computers and military industries and space vehicles …., all of which come from sources of geological, but we do not understand the relationship between the sources of geological product, which are natural sources of biological resources (Biological Resources) include the wealth of plant and animal, are these sources Renewable (Renewable) the possibility of availability in the environment as a result of regenerating naturally. It also includes natural sources of renewable energy sources (Renewable Energy Resources), such as solar and wind power and energy of water.

Are non-renewable resources depletion in the world, and therefore resorted to the countries of the world to find solutions, such as the development of specific technologies able to use available resources efficiently, and reliance on renewable energy sources.

Are also subjected to the depletion of renewable resources, especially plant and animal, soil and XXXXls, it is caused by consumption of these sources at a rate higher than the rate of natural or artificial regeneration. One of the manifestations of attrition as follows:

Depletion of biodiversity and includes; depletion of vegetation cover, and the depletion of wild animals. Fastnzaf vegetation produced by over-cutting, overgrazing, and pollution, natural disasters, fires, volcanoes, drought, and the depletion of wild animals Vintage by overfishing, pollution and the elimination of wildlife habitat, and others.
To protect the biodiversity of attrition, I turned a lot of countries in the world to the establishment of protected areas for wildlife protection and animal and plant habitats, such as nature reserves, in Jordan there are six reserves administered by the Royal Society for the Protection of Nature RSCN, including reserves: Shaumari and Dana and Mujib, blue and others.

The waste delivered by the human, and as a result of increasing population and rising standard of living and industrial development, agricultural and others, led to increased quantities, in addition to the production qualities dangerous to the environment, making the process of collection, transportation and disposal in all countries of the world are important for the health and the environment. The Law on Environmental Protection to Jordan in 1995 on the definition of solid waste materials as a removable and the owner wishes to get rid of them, so that it is collected, transported and processed in the interest of the community.

Water
Besdo water contaminated with iron. Include the following pollutants:
Waste of oxygen-consuming organisms, including pathogens and organic matter from food and plant waste and crop residues and waste water (domestic, industrial and agricultural). These materials are biodegradable, it can be oxidized in the water, so-called oxygen-consuming materials. Result in consumption of dissolved oxygen in water drained, and thus the death of aquatic strangled, such as fish and microorganisms, the air at the same time increase of micro-organisms anaerobic in the water which analyzes the organic materials anaerobically and produces toxic gases and odors resulting from NH3, H2S.
Organic and toxic substances, including oil, and juice in landfill sites. Water pollution affects the oil-water seas and oceans due to leakage of vessels laden with oil from oil wells or the sea. The juice Vtsab groundwater due to leakage from the landfill and dumps her candidacy through the rocks and then they reach groundwater.
Toxic substances, some of these non-organic material source rocks, as the liberated Baltjoah carry running water to lakes or rivers, or permeate the pores of the soil and rock contaminating groundwater. However, the human accelerated mining and processing operations in the liberation of toxic substances from the rocks at a rate thousands of times compared to natural processes. In addition to adding factories, hospitals, farms, and other toxic substances to the ecosystem.

This explains the survival of the cliffs and isolated islands far from the lighting. Number Alpfon decreasing in Europe. Light pollution is a growing phenomenon of changes functional in ecosystems due to artificial lighting in the environment night and especially the negative impact is clear on the types of animal and plant and fungal task (such as insects, night (butterflies and Ghamdiat wings …) and bats and Albermiat …) even the integrity of the environmental scene in general.
Bio-geographical level, this is a very recent phenomenon. For this reason and due to delayed awareness of this problem and the lack of budgets invested in this area, stay away from this risk control. The effects have not been studied carefully, as it did not include the research but some species especially birds.
[Edit] soil pollution
Different types of Alterbhalterbh (Soil) is a loose surface layer of the earth’s crust which blend with the living organisms and products of decaying matter that exist at a depth of 50 to 100 cm. The soil consists of layers called Handles.
Increasing pollution of water bodies steadily, raising questions about the vulnerability of fish by the pollution and dangerous eating human food of different fish, as well as to raise doubts about the true benefits of this important food source
The city of St. Louis is the annual conference of the American scientific research to support AAAS. In the context of the activities of this conference, a damage of environmental pollution on fish, an important topic for discussion. It is known that the meat of fish may contain Tlut by the seas and oceans on the toxic chemicals such as mercury, for example. If you feed the baby in the womb of the mother to a large amount of this XXXXl, it harms the nervous system and affects the fetus in the worst conditions Balichoh congenital disease and physical disability after birth. But it is also known that fish retain a very small amount of mercury in their bodies, but the monitor foodstuffs U.S. FDA years ago wanted to be cautious and advised pregnant women not to eat fish more than twice per week, in the interest of the health of the fetus.
[Edit] global warming
Points capture the temperature of the Alerdhalaanbas warming is the phenomenon of rising temperature in the environment as a result of a change in the flow of thermal energy and the environment. These are often called this name to the phenomenon of global warming than normal. And the causes of this phenomenon on the ground level of any reason for the phenomenon of global warming is divided scientists to say that this phenomenon is a natural phenomenon and that the Earth’s climate is witnessing a natural periods of hot and chilled cold citing this by the ice or cold somewhat between the 17 century and 18 of Europe. The solar radiation is the main source of energy on the surface of the earth, as it stems from the sun towards the earth is implemented through the gas atmosphere in the form of rays of visible short-wave, and X-ray thermal long-wave (infrared) and certain UV rays that can not be absorbed by ozone, Vimits surface Earth radiation hyphen to Faschen then, and the temperature is broadcast around the atmosphere in the form of near-surface temperature Faihtbs, not allowed to access or Alaavlat to the top, and re-broadcast to the ground, leading to increase the degree of the earth. Is beginning to feel the phenomenon of global warming since 1880, if the earth’s atmosphere warmed by half a degree Celsius over the past century, and will increase one degree Celsius by the year 2040 AD is expected to rise some 3.2 ° C up to the year 2100. Cause of carbon dioxide by about 72% of the global warming almost every year adds the world’s population is about 6 billion of this gas to the atmosphere. Came the term greenhouse of the similarity between what happens in Earth’s atmosphere and what is going on in the greenhouse (plastic) used in agriculture, as the sun beats long waves the walls of these houses Vchea heat in the atmosphere of procedure, where the plant, Fathbs Gerdanha ray thermal short waves and prevent them from dropping out, because they do not Tzmha air to escape from the temperature rises than others.
(Carbon dioxide))
[Edit] Tsahraltsahr is subjected land degradation in arid and semi-arid and dry sub-humid, leading to the loss of plant life and biodiversity, and lead to the loss of topsoil and loss of the ability of land for agricultural production and support of animal life and human resources. Desertification affects the catastrophic impact on the economic situation of the country, as it leads to a loss of up to $ 40 billion annually in agricultural crops and increase their prices.
Each year the world loses about 691 square kilometers of agricultural land as a result of the process of desertification, while about one third of the globe vulnerable to desertification in general. The impact of desertification on the African continent in particular, where the desert stretches along the north of Africa, almost. It also became extending south as it approached the equator by 60 km than it was 50 years, and in more than 100 country in the world is affected by almost one billion of the total population of the world’s 6 billion people in the process of desertification of their lands; which force them to leave their farms and migrate to cities to earn a living.
Desertification is the phenomenon of geographical animated, acquired the environment in which the properties of desert real, as a result of the ecological balance of natural, with no deterioration, and a wide range in all environments, wetlands, and sub-humid, dry, semi dry, and under the double impact of the changed circumstances shifts natural plant, through the encroachment of the desert steppe region, the encroachment of the territory of steppes towards the territory of the savannah, the encroachment of the savannah region in the territory of the forest.
Is caused for the deterioration of ecological system, linked to piece the ability of resources, capacity, and if exceeded the exploitation of human resources capacity of, and have been exploited excessive and unregulated, the environment is exposed to deterioration, and becomes Mtssahrh Vtaatnaqs productivity of land, and unable production to meet the needs of human and animal food.

تقرير: عن النفط للصف السابع

تفضلوا هذه مقالة عن النفط … وتحياتي لكم

النفط

النفط أو البترول (كلمة مشتقة من الأصل اللاتيني بيترا والذي يعني صخر، "أوليوم" والتي تعني زيت)، ويطلق عليه أيضا الزيت الخام، كما أن له اسم دارج "الذهب الأسود"، وهو عبارة عن سائل كثيف، قابل للاشتعال، بني غامق أو بني مخضر، يوجد في الطبقة العليا من القشرةالأرضية. وهو يتكون من خليط معقد من الهيدروكربونات، وخاصة من سلسلة الألكانات، ولكنه يختلف في مظهره وتركيبه ونقاوته بشدة من مكان لأخر. وهو مصدر من مصادر الطاقة الأولية الهام للغاية (إحصائيات الطاقة في العالم). البترول هو المادة الخام لعديد من المنتجات الكيماوية، بما فيها الأسمدة، مبيدات الحشرات، اللدائن.::منشأ البترول::المنشأ الحيويينظر معظم الجيولوجيين إلى الزيت الخام، مثل الفحم والغاز الطبيعي، أنه ناتج من تأثير الضغط والحرارة على النباتات القديمة على مر العصور الجيولوجية. وطبقا لهذه النظرية، فقد تكون البترول من تحلل بقايا الحيوانات البحرية ونباتات ما قبل التاريخ. وبمرور قرون عديدة فإن هذه المادة العضوية، إختلطت بالطين، ودفنت تحت طبقات رسوبية من المواد. وأدت الحرارة والضغط الشديدين ألى تحول هذه الحيوانات والنباتات إلى مادة شمعية تسمى كيروجين، وإلى هيدروكربونات سائلة وغازية في عملية تعرف بالتطور التدهوري. وانتقلت هذه المادة خلال طبقات الصخور المجاورة حتى تم إحتجازها تحت الأرض في صخور مسامية تسمي المستودعات، مكونة حقل زيت، والتي يمكن استخلاص السائل منها بالحفر ثم الضخ.المنشأ غير الحيويتوماس جولد كان أكثر العلماء الغربيين تأييدا للنظرية الروسية-الأوكرانية المنشأ الغير حيوي للبترول. وهذه النظرية تفترض ان كميات ضخمة من الكربون الموجود طبيعيا على الأرض، بعضه في شكل هيدروكربونات. ونظرا لأن الهيدروكربونات أقل كثافة من الموائع المسامية، فإنه يتجه للأعلى. وتحوله أشكال الكائنات الدقيقة إلى ترسبات هيدروكربونية عديدة. وأثبتت حسابات الديناميكا الحرارية والدراسات العملية أن "إن-ألكانات" (المكون الرئيسي للبترول) لا تنتج تلقائيا من الميثان في الضغوط الموجودة في الأحواض الرسوبية، وعلى هذا فإن نظرية المنشأ الغير حيوي للهيدروكربونات تفترض التكون العميق.::تركيب البترول::أثناء عمليات التصفية، يتم فصل الكيماويات المكونة للبترول عن طريق التقطير التجزيئي، وهو عملية فصل تعتمد على نقط الغليان النسبية (أو قابلية التطاير النسبية). المنتجات المختلفة (بالترتيب طبقا لنقطة غليانها) بما فيها الغازت الخفيفة (مثل: الميثان، الإيثان، البروبان) كالتالي: البنزين، وقود المحركات النفاثة، الكيروسين، الديزل، الجازولين، شموع البرافين، الأسفلت، وهكذا. والتقنيات الحديثة مثل فصل الألوان الغازي، Hplc، فصل ألوان غازي-مطياف كتلة، يمكن أن تفصل بعض الأجزاء من البترول إلى مركبات فردية، وهذه طريقة من طرقالكيمياء التحليلية، تستخدم غالبا في أقسام التحكم في الجودة في مصافي البترول.ولمزيد من الدقة، فإن البترول يتكون منالهيدروكربونات، وهذه بدورها تتكون منالهيدروجين، والكربون، وبعض الأجزاء غير الكربونية والتي يمكن أن تحتوي على النيتروجين، الكبريت، الأين، وبعض الكميات الضئيلة من الفلزات مثل الفاناديوم أو النيكل، ومثل هذه العناصر لا تتعدى 1% من تركيب البترول.وأخف أربعة ألكانات هم: ميثان Ch4، إيثان C2h6، بروبان C3h8، بيوتان C4h10. وهم جميعا غازات. ونقطة غليانهم -161.6 C° و -88 C° و -42 C° و -0.5 C°، بالترتيب (-258.9، -127.5، -43.6، -31.1 F°)مدى السلاسل C5-7 كلها خفيفة، وتتطاير بسهولة، نافثا نقية. ويتم استخدامهم كمذيبات، سوائل التنظيف الجاف، ومنتجات التجفيف السريع الأخرى. أما السلاسل من C6h14 إلى C12h26 تكون مختلطة ببعض وتستخدم في الجازولين. ويتم صنع الكيروسين من السلاسل C10 إلى C15، ثم وقود الديزل/زيت التسخين في المدى من C10 إلى C20، و يتم استخدم زيوت الوقود الأثقل من ذلك في محركات السفن. وجميع هذه المركبات البترولية سائلة في درجة حرارة الغرفة.زيوت التشحيم والشحم شبه الصلب (بما فيه الفزلين) تتراوح من C16 إلى C20.السلاسل الأعلى من C20 تكون صلبة، بداية من شمع البرافين، ثم بعد ذلك القطران، القار، الأسفلت.مدى درجات الغليان لمكونات البترول تحت تأثير الضغط الجوي في التقطير التجزيئي بالدرجة المئوية:إثير بترول: 40 – 70 C° يستخدم كمذيب بنزين خفيف: 60 – 100 C° يستخدم كوقود للسيارات بنزين ثقيل: 100- 150 C° يستخدم كوقود للسيارات كيروسين خفيف: 120 – 150 C° يستخدم كمذيب ووقود للمنازل كيروسين: 150 – 300 C° يستخدم كوقود للمحركات النفاثة زيت الغاز: 250 – 350 C° يستخدم كوقود للديزل / للتسخين زيت تشحيم: > 300 C° يستخدم زيت محركات الأجزاء التبقية: قار، أسفلت، وقود متبقي.::استخلاص البترول::بصفة عامة فإن المرحلة الأولى في استخلاص الزيت الخام هي حفر بئر ليصل لمستودعات البترول تحت الأرض. وغالبا ما يتم حفر عديد من الآبار لنفس المستودع، للحصول على معدل استخراج اقتصادي. وفي بعض الآبار يتم ضخ الماء، البخار، مخلوط الغازات المختلفة للمستودع لإبقاء معدلات الاستخراج الاقتصادية مستمرة.وفي حالة أن الضغط تحت الأرض في مستودع الغاز كافي، عندها سيجبر الزيت على الخروج للسطح تحت تأثير هذا الضغط. الوقود الغازي أو الغاز الطبيعي غالبا ما يكون متواجد، مما يزيد من الضغط الموجود تحت الأرض. وفي هذه الحالة فإن الضغط يكون كافي لوضع كمية كافة من الصمامات على رأس البئر لتوصيل البئر بشبكة الأنابيب للتخزين، وعمليات التشغيل. ويسمى هذا استخلاص الزيت المبدئى. وتقريبا 20% فقط من الزيت في المستودع يمكن استخراجه بهذه الطريقة.وخلال فترة حياة البئر يقل الضغط، وعند حدود معينة لا يكون كافيا لدفع الزيت للسطح. وعندها، لو أن المتبقى قى البئر كافي اقتصاديا، وغالبا ما يكون كذلك، يتم استخراج الزيت المتبقي في البئر بطريقة استخراج الزيت الإضافية. شاهد إتزان الطاقة، وصافي الطاقة. ويتم استخدام تقنيات مختلفة في طريقة استخراج الزيت الإضافية، لاستخراج الزيت من المستودعات التي نفذ ضغطها أو قل. يستخدم أحيانا الضخ بالطلمبات مثل الطلمبات المستمرة، وطلمبة الأعماق الكهربية (electrical submersible pumps ESPs) لرفع الزيت إلى السطح. وتستخدم تقنية مساعدة لزيادة ضغط المستودع عن طريق حقن الماء، إعادة حقن الغاز الطبيعي، رفع الغاز وهذا يقوم بحقن الهواء، ثاني أكسيد الكربون أو غازات أخرى للمستودع. وتعمل الطريقتان معا المبدئية والإضافية على استخراج ما يقرب من 25 إلى 35% من المستودع.المرحلة الثالثة في استخراج الزيت تعتمد على تقليل كثافة الزيت لتعمل على زيادة الإنتاج. وتبدأ هذه المرحلة عندما لا تستطيع كل من الطريقة المبدئة، والطريقة الإضافية على استخراج الزيت، ولكن بعد التأكد من جدوى استخدام هذه الطريقة اقتصاديا، وما إذا كان الزيت الناتج سيغطي تكاليف الإنتاج والأرباح المتوقعة من البئر. كما يعتمد أيضا على أسعار البترول وقتها، حيث يتم إعادة تشغيل الآبار التي قد تكون توقفت عن العمل في حالة ارتفاع أسعار الزيت. طرق استخراج الزيت المحسن حراريا (Thermally-enhanced oil recovery methods TEOR) هي الطريقة الثالثة في ترتيب استخراج الزيت، والتي تعتمد على تسخين الزيت وجعله أسهل للاستخراج. حقن البخار هي أكثر التقنيات استخداما في هذه الطريقة، وغالبا مع تتم (TEOR) عن طريق التوليد المزدوج. وفكرة عمل التوليد المزدوج هي استخدم تربينة (توربينة) غاز لإنتاج الكهرباء واستخدام الحرارة المفقودة الناتجة عنها لإنتاج البخار، الذي يتم حقنه للمستودع.وكما قال الدكتور عثمان العبدلي بأن هناك تقنية أخرى تستخدم في طريقة (TEOR)، وهي الحرق في-الموضع، وفيها يتم إحراق الزيت لتسخين الزيت المحيط به. وأحيانا يتم استخدام المنظفات لتقليل كثافة الزيت. ويتم استخراج ما يقرب من 5 إلى 15% من الزيت في هذه المرحلة ،,؛؛طرق أخرى لإنتاج الزيت؛؛,,نظرا للزيادة المستمرة في أسعار البترول، أصبحت الطرق الأخرى لإنتاج الزيت محل إهتمام. وأصلح هذه الأفكار هو تحويل الفحم إلى زيت والتي تهدف إلى تحويل الفحم إلى زيت خام.وكانت تعرف "إيرساتز" ("الاستبدال" ). وقد تم توقف هذه الطريقة بعد ذلك نظرا لأن تكاليف إنتاج البترول الطبيعي أقل منها. ولكن بالنظر إلى ارتفاع أسعار البترول المستمر، فإن تحويل الفحم إلى بترول قد يكون محل تفكير.وتتضمن الطريقة تحويل رماد الفحم إلى زيت في عملية متعددة المراحل. ونظريا فإن طن من الفحم ينتج نقريبا 200 لتر من الخام، بمنتجات تتراوح من القار إلى الكيماويات النادرة تم حفر أول بئر للبترول في الصين في القرن الرابع الميلادي أوقبل ذلك. وكان يتم إحراق الزيت لتبخير الماء المالح لإنتاج الملح. وبحلول القرن العاشر، تم استخدام أنابيبالخيرزان لتوصيل الأنابيب لمنابع المياه المالحة.في القرن الثامن الميلادي، كان يتم رصف الطرق الجديدة فيبغداد باستخدامالقار، الذي كان يتم إحضاره من من ترشحات البترول في هذه المنطقة. في القرن التاسع الميلادي، بدأت حقول البترول في باكو، أذربيجان بإنتاج البترول بطريقة اقتصادية لأول مرة. وكان يتم حفر هذه الحقول للحصول على النفط، وتم وصف ذلك بمعرفة الجغرافي ماسودي في القرن العاشر الميلادي، وأيضا ماركو بولو في القرن الثالث عشر الميلادي، الذي وصف البترول الخارج من هذه الآبار بقوله أنها مثل حمولة مئات السفن. شاهد أيضا الحضارة الإسلامية.ويبدأ التاريخ الحديث للبترول في عام 1853، باكتشاف عملية تقطير البترول. فقد تم تقطير البترول والحصول منه على الكيروسين بمعرفة إجناسى لوكاسفيز، وهو عالم بولندي. وكان أول منجم زيت صخري يتم إنشائه في بوربكا، بالقرب منكروسنو في جنوب بولندا، وفي العام التالي لذلك تم بناء أول معمل تكرير (في الحقيقة تقطير) في يولازوفايز، وكان أيضا عن طريق لوكاسفيز. وإنتشرت هذه الاكتشافات سريعا في العالم، وقام ميرزوف ببناء أول معمل تقطير في روسيا في حقل الزيت الطبيعي في باكو في عام 1861
