Two different concepts to encourage poor countries to cut their emissions. The first would entail them being awarded if they hit their targets, but not punished if they miss them and the second would entail poor countries accepting limitations on emissions from certain industries, such as iron and steel, but not from their economies on a whole

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
