Liquefied natural gas
Liquefied natural gas is natural gas that has been converted to liquid form for ease of storage or transport. It takes up about 1/600th the volume of gas in the gaseous state. It is odorless, colorless and non-corrosive, hazards include flammability after vaporization into a gaseous state and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C. LNG achieves a reduction in volume than compressed natural gas so that the energy density of LNG is 2.4 times greater than that of CNG or 60 percent that of diesel fuel. This makes LNG cost efficient to transport long distances where pipelines do not exist. Specially designed cryogenic sea vessels or cryogenic road tankers are used for its transport, LNG is principally used for transporting natural gas to markets, where it is regasified and distributed as pipeline natural gas.
It can be used in natural gas vehicles, although it is common to design vehicles to use compressed natural gas. Its relatively high cost of production and the need to store it in expensive cryogenic tanks have hindered widespread commercial use, despite these drawbacks, on energy basis LNG production is expected to hit 10% of the global crude production by 2020. The heating value depends on the source of gas that is used, the range of heating value can span +/-10 to 15 percent. A typical value of the heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. A typical value of the heating value of LNG is 45 MJ/kg or 19,350 BTU/lb. For the purpose of comparison of different fuels the heating value may be expressed in terms of energy per volume which is known as the energy density expressed in MJ/liter. The density of LNG is roughly 0.41 kg/liter to 0.5 kg/liter, depending on temperature, using the median value of 0.45 kg/liter, the typical energy density values are 22.5 MJ/liter or 20.3 MJ/liter.
The energy density of LNG is approximately 2.4 times greater than that of CNG which makes it economical to transport natural gas by ship in the form of LNG. The energy density of LNG is comparable to propane and ethanol but is only 60 percent that of diesel and 70 percent that of gasoline, experiments on the properties of gases started early in the seventeenth century. By the middle of the seventeenth century Robert Boyle had derived the relationship between the pressure and the volume of gases
Bahrain, officially the Kingdom of Bahrain, is a small Arab monarchy in the Persian Gulf. Bahrains population is 1,234,567, including 666,172 non-nationals and it is 780 km2 in size, making it the third smallest nation in Asia after the Maldives and Singapore. Bahrain is the site of the ancient Dilmun civilisation and it has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to convert to Islam, following a period of Arab rule, Bahrain was occupied by the Portuguese in 1521, who in turn were expelled in 1602 by Shah Abbas I of the Safavid dynasty under the Persian Empire. In 1783, the Bani Utbah clan captured Bahrain from Nasr Al-Madhkur and it has since been ruled by the Al Khalifa royal family, in the late 1800s, following successive treaties with the British, Bahrain became a protectorate of the United Kingdom. Formerly a state, Bahrain was declared a Kingdom in 2002, in 2011, the country experienced protests inspired by the regional Arab Spring.
Bahrain had the first post-oil economy in the Persian Gulf, since the late 20th century, Bahrain has invested in the banking and tourism sectors. Many large financial institutions have a presence in Manama, the countrys capital, Bahrain has a high Human Development Index and was recognised by the World Bank as a high income economy. In Arabic, Bahrayn is the form of bahr, so al-Bahrayn means the two seas, although which two seas were originally intended remains in dispute. The term appears five times in the Quran, but does not refer to the modern island—originally known to the Arabs as Awal— but rather to all of Eastern Arabia. Today, Bahrains two seas are generally taken to be the bay east and west of the island. In addition to wells, there are areas of the sea north of Bahrain where fresh water bubbles up in the middle of the water as noted by visitors since antiquity. An alternate theory with regard to Bahrains toponymy is offered by the al-Ahsa region, another supposition by al-Jawahari suggests that the more formal name Bahri would have been misunderstood and so was opted against.
Until the late Middle Ages, Bahrain referred to the region of Eastern Arabia that included Southern Iraq, Kuwait, Al-Hasa, the region stretched from Basra in Iraq to the Strait of Hormuz in Oman. This was Iqlīm al-Bahrayns Bahrayn Province, the exact date at which the term Bahrain began to refer solely to the Awal archipelago is unknown. The entire coastal strip of Eastern Arabia was known as Bahrain for a millennium, the island and kingdom were commonly spelled Bahrein into the 1950s. Bahrain was home to the Dilmun civilization, an important Bronze Age trade centre linking Mesopotamia, Bahrain was ruled by the Assyrians and Babylonians. From the 6th to 3rd century BC, Bahrain was part of the Persian Empire ruled by the Achaemenian dynasty, by about 250 BC, Parthia brought the Persian Gulf under its control and extended its influence as far as Oman
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power.
The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations.
In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD.
Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭.
It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon
Houston is the most populous city in the state of Texas and the fourth-most populous city in the United States. With a census-estimated 2014 population of 2.239 million within an area of 667 square miles, it is the largest city in the southern United States and the seat of Harris County. Located in Southeast Texas near the Gulf of Mexico, it is the city of Houston–The Woodlands–Sugar Land. Houston was founded on August 28,1836, near the banks of Buffalo Bayou and incorporated as a city on June 5,1837. The city was named after former General Sam Houston, who was president of the Republic of Texas and had commanded, the burgeoning port and railroad industry, combined with oil discovery in 1901, has induced continual surges in the citys population. Houstons economy has an industrial base in energy, aeronautics. Leading in health care sectors and building equipment, Houston has more Fortune 500 headquarters within its city limits than any city except for New York City. The Port of Houston ranks first in the United States in international waterborne tonnage handled, the city has a population from various ethnic and religious backgrounds and a large and growing international community.
Houston is the most diverse city in Texas and has described as the most diverse in the United States. It is home to cultural institutions and exhibits, which attract more than 7 million visitors a year to the Museum District. Houston has a visual and performing arts scene in the Theater District. In August 1836, two real estate entrepreneurs from New York, Augustus Chapman Allen and John Kirby Allen, purchased 6,642 acres of land along Buffalo Bayou with the intent of founding a city. The Allen brothers decided to name the city after Sam Houston, the general at the Battle of San Jacinto. The great majority of slaves in Texas came with their owners from the slave states. Sizable numbers, came through the slave trade. New Orleans was the center of trade in the Deep South. Thousands of enslaved African Americans lived near the city before the Civil War, many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs. Houston was granted incorporation on June 5,1837, with James S.
Holman becoming its first mayor, in the same year, Houston became the county seat of Harrisburg County and the temporary capital of the Republic of Texas
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as coal, can be regarded as metamorphic rock because of exposure to elevated temperature and pressure. Coal is composed primarily of carbon, along with quantities of other elements, chiefly hydrogen, oxygen. A fossil fuel, coal forms when plant matter is converted into peat, which in turn is converted into lignite, sub-bituminous coal, after that bituminous coal. This involves biological and geological processes that take place over time, throughout history, coal has been used as an energy resource, primarily burned for the production of electricity and heat, and is used for industrial purposes, such as refining metals. Coal is the largest source of energy for the generation of electricity worldwide, the extraction of coal, its use in energy production and its byproducts are all associated with environmental and health effects including climate change.
Coal is extracted from the ground by coal mining, since 1983, the worlds top coal producer has been China. In 2015 China produced 3,747 million tonnes of coal –47. 7% of 7,861 million tonnes world coal production, in 2015 other large producers were United States, European Union and Australia. The word originally took the col in Old English, from Proto-Germanic *kula. In Old Turkic languages, kül is ash, cinders, öčür is quench, the compound charcoal in Turkic is öčür kül, literally quenched ashes, coals with elided anlaut ö- and inflection affixes -ülmüş. At various times in the geologic past, the Earth had dense forests in low-lying wetland areas, due to natural processes such as flooding, these forests were buried underneath soil. As more and more soil deposited over them, they were compressed, the temperature rose as they sank deeper and deeper. As the process continued the plant matter was protected from biodegradation and oxidation and this trapped the carbon in immense peat bogs that were eventually covered and deeply buried by sediments.
Under high pressure and high temperature, dead vegetation was slowly converted to coal, as coal contains mainly carbon, the conversion of dead vegetation into coal is called carbonization. The wide, shallow seas of the Carboniferous Period provided ideal conditions for coal formation, the exception is the coal gap in the Permian–Triassic extinction event, where coal is rare. Coal is known from Precambrian strata, which predate land plants — this coal is presumed to have originated from residues of algae, in its dehydrated form, peat is a highly effective absorbent for fuel and oil spills on land and water. It is used as a conditioner for soil to make it able to retain. Lignite, or brown coal, is the lowest rank of coal, jet, a compact form of lignite, is sometimes polished and has been used as an ornamental stone since the Upper Palaeolithic
Petroleum is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earths surface, which is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation and it consists of hydrocarbons of various molecular weights and other organic compounds. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock, Petroleum has mostly been recovered by oil drilling. Drilling is carried out studies of structural geology, sedimentary basin analysis. Petroleum is used in manufacturing a variety of materials. Concern over the depletion of the earths finite reserves of oil, the burning of fossil fuels plays the major role in the current episode of global warming. The word petroleum comes from Greek, πέτρα for rocks and Greek, the term was found in 10th-century Old English sources.
It was used in the treatise De Natura Fossilium, published in 1546 by the German mineralogist Georg Bauer, Petroleum, in one form or another, has been used since ancient times, and is now important across society, including in economy and technology. Great quantities of it were found on the banks of the river Issus, ancient Persian tablets indicate the medicinal and lighting uses of petroleum in the upper levels of their society. By 347 AD, oil was produced from bamboo-drilled wells in China, early British explorers to Myanmar documented a flourishing oil extraction industry based in Yenangyaung that, in 1795, had hundreds of hand-dug wells under production. The mythological origins of the oil fields at Yenangyaung, and its hereditary monopoly control by 24 families, Pechelbronn is said to be the first European site where petroleum has been explored and used. The still active Erdpechquelle, a spring where petroleum appears mixed with water has been used since 1498, Oil sands have been mined since the 18th century.
In Wietze in lower Saxony, natural asphalt/bitumen has been explored since the 18th century, both in Pechelbronn as in Wietze, the coal industry dominated the petroleum technologies. In 1848 Young set up a small business refining the crude oil, Young eventually succeeded, by distilling cannel coal at a low heat, in creating a fluid resembling petroleum, which when treated in the same way as the seep oil gave similar products. The production of oils and solid paraffin wax from coal formed the subject of his patent dated 17 October 1850. In 1850 Young & Meldrum and Edward William Binney entered into partnership under the title of E. W. Binney & Co. at Bathgate in West Lothian, the worlds first oil refinery was built in 1856 by Ignacy Łukasiewicz. The demand for petroleum as a fuel for lighting in North America, edwin Drakes 1859 well near Titusville, Pennsylvania, is popularly considered the first modern well
The Middle East is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is Middle-Eastern and the noun is Middle-Easterner. The term has come into usage as a replacement of the term Near East beginning in the early 20th century. Arabs, Persians and Azeris constitute the largest ethnic groups in the region by population. Indigenous minorities of the Middle East include Jews and other Arameans, Berbers, Druze, Mandaeans, Shabaks, Tats, in the Middle East, there is a Romani community. European ethnic groups form a diaspora in the region include Albanians, Circassians, Crimean Tatars, Franco-Levantines. Among other migrant populations are Bengalis as well as other Indians, Filipinos, Pakistanis, the history of the Middle East dates back to ancient times, with the importance of the region being recognized for millennia. Most of the countries border the Persian Gulf have vast reserves of crude oil. The term Middle East may have originated in the 1850s in the British India Office, however, it became more widely known when American naval strategist Alfred Thayer Mahan used the term in 1902 to designate the area between Arabia and India.
During this time the British and Russian Empires were vying for influence in Central Asia, Mahan realized not only the strategic importance of the region, but of its center, the Persian Gulf. Mahan first used the term in his article The Persian Gulf and International Relations, published in September 1902 in the National Review, a British journal. The Middle East, if I may adopt a term which I have not seen, will some day need its Malta, as well as its Gibraltar, it does not follow that either will be in the Persian Gulf. The British Navy should have the facility to concentrate in force if occasion arise, about Aden, mahans article was reprinted in The Times and followed in October by a 20-article series entitled The Middle Eastern Question, written by Sir Ignatius Valentine Chirol. During this series, Sir Ignatius expanded the definition of Middle East to include regions of Asia which extend to the borders of India or command the approaches to India. After the series ended in 1903, The Times removed quotation marks from subsequent uses of the term, in the late 1930s, the British established the Middle East Command, which was based in Cairo, for its military forces in the region.
After that time, the term Middle East gained broader usage in Europe, the description Middle has led to some confusion over changing definitions. Before the First World War, Near East was used in English to refer to the Balkans and the Ottoman Empire, while Middle East referred to Iran, the Caucasus, Central Asia, and Turkestan. The first official use of the term Middle East by the United States government was in the 1957 Eisenhower Doctrine, the Associated Press Stylebook says that Near East formerly referred to the farther west countries while Middle East referred to the eastern ones, but that now they are synonymous
The Financial Times is an English-language international daily newspaper with a special emphasis on business and economic news. The paper and owned by Nikkei Inc. in Tokyo, was founded in 1888 by James Sheridan and Horatio Bottomley, and merged in 1945 with its closest rival, the Financial Times has an average daily readership of 2.2 million people worldwide. FT. com has 4.5 million registered users and over 285,000 digital subscribers, FT Chinese has more than 1.7 million registered users. The world editions of the Financial Times newspaper had an average daily circulation of 234,193 copies in January 2014. In February 2014 the combined sale of the editions of the Financial Times was 224,000 copies. In October 2013 the combined print and digital circulation of the Financial Times reached nearly 629,000 copies. In December 2016 print sales for the paper stood at 193,211, on 23 July 2015 Nikkei Inc. agreed to buy the Financial Times from Pearson for £844m. On 30 November 2015 Nikkei completed the acquisition, the FT was launched as the London Financial Guide on 10 January 1888, renaming itself the Financial Times on 13 February the same year.
Describing itself as the friend of The Honest Financier, the Bona Fide Investor, the Respectable Broker, the Genuine Director, the readership was the financial community of the City of London, its only rival being the slightly older and more daring Financial News. After 57 years of rivalry the Financial Times and the Financial News were merged in 1945 by Brendan Bracken to form a single six-page newspaper, the Financial Times brought a higher circulation while the Financial News provided much of the editorial talent. The Lex column was introduced from Financial News. Pearson bought the paper in 1957, over the years the paper grew in size and breadth of coverage. It established correspondents in cities around the world, reflecting early moves in the economy towards globalisation. On 1 January 1979 the first FT was printed outside the UK, since then, with increased international coverage, the FT has become a global newspaper, printed in 22 locations with five international editions to serve the UK, continental Europe, the U. S.
The European edition is distributed in continental Europe and Africa and it is printed Monday to Saturday at five centres across Europe reporting on matters concerning the European Union, the Euro and European corporate affairs. In 1994 FT launched a lifestyle magazine, How To Spend It. In 2009 it launched a website for the magazine. On 13 May 1995 the Financial Times group made its first foray into the world with the launch of FT. com
In economics, a commodity is a marketable item produced to satisfy wants or needs. Economic commodities comprise goods and services, the word commodity came into use in English in the 15th century, from the French commodité, convenience. Going further back, the French word derives from the Latin commoditas, meaning suitability, the Latin word commodus meant variously appropriate, proper measure, time, or condition, and advantage, benefit. The term commodity is specifically used for a good or service when the demand for it has no qualitative differentiation across a market. In other words, a commodity good or service has full or partial but substantial fungibility, that is, the market treats its instances as equivalent or nearly so with no regard to who produced them. As the saying goes, From the taste of wheat, it is not possible to tell who produced it, a Russian serf and copper are other examples of such commodities, their supply and demand being a part of one universal market. Items such as systems, on the other hand, have many aspects of product differentiation, such as the brand, the user interface.
The demand for one type of stereo may be larger than demand for another. In contrast, one of the characteristics of a commodity good is that its price is determined as a function of its market as a whole, well-established physical commodities have actively traded spot and derivative markets. Generally, these are basic resources and agricultural products such as ore, sugar. Soft commodities are goods that are grown, while hard commodities are ones that are extracted through mining, there is another important class of energy commodities which includes electricity, gas and oil. Electricity has the characteristic that it is usually uneconomical to store, hence. Commoditization occurs as a goods or services market loses differentiation across its supply base, as such, goods that formerly carried premium margins for market participants have become commodities, such as generic pharmaceuticals and DRAM chips. Following this trend, nanomaterials are emerging from carrying premium profit margins for market participants to a status of commodification, there is a spectrum of commoditization, rather than a binary distinction of commodity versus differentiable product.
Many products degree of commoditization depends on the mentality and means. For example, milk and notebook paper are not differentiated by many customers, for them, other customers take into consideration other factors besides price, such as environmental sustainability and animal welfare. This is a list of companies trading globally in commodities, descending by size as of October 28,2011, on a commodity exchange, it is the underlying standard stated in the contract that defines the commodity, not any quality inherent in a specific producers product. Commodities exchanges include, Bourse Africa Bursa Malaysia Derivatives Chicago Board of Trade Chicago Mercantile Exchange Dalian Commodity Exchange Euronext and these markets will quickly respond to changes in supply and demand to find an equilibrium price and quantity
Singapore, officially the Republic of Singapore, sometimes referred to as the Lion City or the Little Red Dot, is a sovereign city-state in Southeast Asia. It lies one degree north of the equator, at the tip of peninsular Malaysia. Singapores territory consists of one island along with 62 other islets. Since independence, extensive land reclamation has increased its size by 23%. During the Second World War, Singapore was occupied by Japan, after early years of turbulence, and despite lacking natural resources and a hinterland, the nation developed rapidly as an Asian Tiger economy, based on external trade and its workforce. Singapore is a global commerce and transport hub, the country has been identified as a tax haven. Singapore ranks 5th internationally and first in Asia on the UN Human Development Index and it is ranked highly in education, life expectancy, quality of life, personal safety, and housing, but does not fare well on the Democracy index. Although income inequality is high, 90% of homes are owner-occupied, 38% of Singapores 5.6 million residents are permanent residents and other foreign nationals.
There are four languages on the island, Mandarin, Tamil. English is its language, most Singaporeans are bilingual. Singapore is a multiparty parliamentary republic, with a Westminster system of unicameral parliamentary government. The Peoples Action Party has won every election since self-government in 1959, however, it is unlikely that lions ever lived on the island, Sang Nila Utama, the Srivijayan prince said to have founded and named the island Singapura, perhaps saw a Malayan tiger. There are however other suggestions for the origin of the name, the central island has been called Pulau Ujong as far back as the third century CE, literally island at the end in Malay. In 1299, according to the Malay Annals, the Kingdom of Singapura was founded on the island by Sang Nila Utama and these Indianized Kingdoms, a term coined by George Cœdès were characterized by surprising resilience, political integrity and administrative stability. In 1613, Portuguese raiders burned down the settlement, which by was part of the Johor Sultanate.
The wider maritime region and much trade was under Dutch control for the following period, in 1824 the entire island, as well as the Temenggong, became a British possession after a further treaty with the Sultan. In 1826, Singapore became part of the Straits Settlements, under the jurisdiction of British India, prior to Raffles arrival, there were only about a thousand people living on the island, mostly indigenous Malays along with a handful of Chinese. By 1860 the population had swelled to over 80,000, many of these early immigrants came to work on the pepper and gambier plantations
