Natural gas Wikipedia. Natural gas is a naturally occurring hydrocarbongas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas. Natural gas is a fossil fuel used as a source of energy for heating, cooking, and electricity generation. It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals. Fossil fuel based natural gas is a non renewable resource. Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates. Petroleum is another resource and fossil fuel found in close proximity to and with natural gas. Most natural gas was created over time by two mechanisms biogenic and thermogenic. Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and.

Biogenic gas is created by methanogenic organisms in marshes, bogs, landfills, and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from buried organic material. In petroleum production gas is often burnt as flare gas. The World Bank estimates that over 1. Before natural gas can be used as a fuel, most, but not all, must be processed to remove impurities, including water, to meet the specifications of marketable natural gas. The by products of this processing include ethane, propane, butanes, pentanes, and higher molecular weight hydrocarbons, hydrogen sulfide which may be converted into pure sulfur, carbon dioxide, water vapor, and sometimes helium and nitrogen.

Innovate Biotech 2017 is the meeting place for Biotechnology, Biotech Engineers, Biotech Scientists, Recombinant DNA Technologists, Biotechnology Professors Biotech. It is wellestablished that microalgalderived biofuels have the potential to make a significant contribution to the US fuel market, due to several unique. Natural gas is often informally referred to simply as gas, especially when compared to other energy sources such as oil or coal. However, it is not to be confused with gasoline, especially in North America, where the term gasoline is often shortened in colloquial usage to gas. HistoryeditNatural gas was discovered accidentally in ancient China, as it resulted from the drilling for brines. The natural gas was used to boil brine to make salt. Natural gas was first used by the Chinese in about 5. BCE possibly even 1.

They discovered a way to transport gas seeping from the ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt,9 in the Ziliujing District of Sichuan. The worlds first industrial extraction of natural gas started at Fredonia, New York, United States, in 1.

For some time, GEA has set the standard for very high pressure VHP homogenizer units for pharmaceutical and biotechnology applications. By 2. 00. 9, 6. 6 0. Based on an estimated 2. An annual increase in usage of 23 could result in currently recoverable reserves lasting significantly less, perhaps as few as 8. Natural gas coming out of the ground in Taiwan. SourceseditNatural gasedit. Trends in the top five natural gas producing countries US EIA dataIn the 1. Unwanted natural gas was a disposal problem in the active oil fields. If there was not a market for natural gas near the wellhead it was prohibitively expensive to pipe to the end user. In the 1. 9th century and early 2. Today, unwanted gas or stranded gas without a market associated with oil extraction often is returned to the reservoir with injection wells while awaiting a possible future market or to repressurize the formation, which can enhance extraction rates from other wells. In regions with a high natural gas demand such as the US, pipelines are constructed when it is economically feasible to transport gas from a wellsite to an end consumer. In addition to transporting gas via pipelines for use in power generation, other end uses for natural gas include export as liquefied natural gas LNG or conversion of natural gas into other liquid products via gas to liquids GTL technologies. GTL technologies can convert natural gas into liquids products such as gasoline, diesel or jet fuel. A variety of GTL technologies have been developed, including FischerTropsch FT, methanol to gasoline MTG and STG. FT produces a synthetic crude that can be further refined into finished products, while MTG can produce synthetic gasoline from natural gas. STG can produce drop in gasoline, diesel, jet fuel and aromatic chemicals directly from natural gas via a single loop process. In 2. 01. 1, Royal Dutch Shells 1. FT plant went into operation in Qatar. Natural gas can be associated found in oil fields, or non associated isolated in natural gas fields, and is also found in coal beds as coalbed methane. It sometimes contains a significant amount of ethane, propane, butane, and pentaneheavier hydrocarbons removed for commercial use prior to the methane being sold as a consumer fuel or chemical plant feedstock. Non hydrocarbons such as carbon dioxide, nitrogen, helium rarely, and hydrogen sulfide must also be removed before the natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas whether or not truly produced up the annulus and through a casinghead outlet or associated gas. The natural gas industry is extracting an increasing quantity of gas from challenging resource types sour gas, tight gas, shale gas, and coalbed methane. There is some disagreement on which country has the largest proven gas reserves. Sources that consider that Russia has by far the largest proven reserves include the US CIA 4. US Energy Information Administration 4. OPEC 4. 8 7. 00 km. However, BP credits Russia with only 3. Iran 3. 3 1. 00 to 3. With Gazprom, Russia is frequently the worlds largest natural gas extractor. Major proven resources in cubic kilometers are world 1. Iran 3. 3 6. 00 2. Russia 3. 2 9. 00 2. Qatar 2. 5 1. 00 2. Turkmenistan 1. 7 5. United States 8. 50. It is estimated that there are about 9. In turn, many studies from MIT, Black Veatch and the DOE predict that natural gas will account for a larger portion of electricity generation and heat in the future. The worlds largest gas field is the offshore South Pars North Dome Gas Condensate field, shared between Iran and Qatar. It is estimated to have 5. Because natural gas is not a pure product, as the reservoir pressure drops when non associated gas is extracted from a field under supercritical pressuretemperature conditions, the higher molecular weight components may partially condense upon isothermic depressurizingan effect called retrograde condensation. The liquid thus formed may get trapped as the pores of the gas reservoir get depleted. One method to deal with this problem is to re inject dried gas free of condensate to maintain the underground pressure and to allow re evaporation and extraction of condensates. More frequently, the liquid condenses at the surface, and one of the tasks of the gas plant is to collect this condensate. The resulting liquid is called natural gas liquid NGL and has commercial value. Shale gasedit. The location of shale gas compared to other types of gas deposits. Shale gas is natural gas produced from shale. Because shale has matrix permeability too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow.
