A Nodding Donkey provides the up/down motion (stroke) that powers a submersible pump in a borehole. The submersible pumps oil in a similar way to which a bicycle pump pumps air into a tyre
Nitrogen oxides include various nitrogen compounds, primarily nitric oxide (NO) and nitrogen dioxide (NO2). They form when fossil fuels are burned at high temperatures and react with volatile organic compounds to form ozone, the main component of urban smog. They are also precursor pollutants that contribute to the formation of acid rain and to impairment of visibility.
It is not unusual to discover natural gas deposits containing substantial levels of nitrogen. More often than not, these discoveries are not developed because the nitrogen levels exceed the four percent inert requirement for pipeline gas. A Nitrogen Rejection System may provide an economically practical approach to the development of these resources. Nitrogen rejection can be accomplished in several ways. Three of the most commonly used methodologies include cryogenic systems, techniques that utilize a solvent for hydrocarbon recovery, and the pressure swing adsorption process. The technology chosen for removing nitrogen depends largely on a number of variables including the volume of gas to be processed, the quantity of natural gas liquids present in the methane mix, and the nitrogen level in the gas. > >
A class of polluting emissions produced by the consumption of fossil fuels, especially by automobiles and coal-fired generating stations. Nitrogen oxides are converted to acids, usually highly corrosive nitric acid, when exposed to water molecules in the atmosphere, and this eventually falls to earth as acid rain
The world’s largest physical commodity futures exchange, located in New York City which handles billions of dollars worth of energy products, metals and other commodities being bought and sold on the trading floor and the overnight electronic trading computer systems. The prices quoted for transactions on the exchange are the basis for prices that people pay for throughout the world
Nesher enjoys financial strength, which stems from its joint ownership by Clal Industries, one of Israel’s largest investment companies, which belongs to the IDB Group, and CRH, a leading consortium in the international construction market. Nesher is Israel’s sole producer of cement. In 31.8.2006 Nesher received a generation license for a 48 MW open cycle conventional IPP. In January 2007, EMG signed a contract to supply Nesher with $10 million of natural gas under a 15 year contract at a gas price of $3.70 – $4.50 mmbtu. In November 2009 the Nesher cement cogeneration plant started to generate electricity.
A system giving customers a right of access to transmission and distribution systems on the basis of negotiated tariffs. It thus enables to provide spare capacity in pipelines to third parties upon payment of a negotiated tariff. Since tension often exists between the owners of fields and the owners of infrastructure, in many areas a code of practice has been put in place. This helps to streamline and facilitate the timely application of the processes of seeking, offering and negotiating third party access to offshore pipelines and processing facilities as well as onshore terminals. It helps to ensure that access is easy and fair, with terms offered on a negotiated but non discriminatory basis
