NO x gases are usually produced from the reaction between nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines. [1] [2] [3] In areas of high motor vehicle traffic, such as in large cities, the nitrogen oxides emitted can be a significant source of air pollution.
Nitroethane is an organic compound having the chemical formula C 2 H 5 NO 2. Similar in many regards to nitromethane , nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor.
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
The reaction produces fragments from the parent alkane, creating a diverse mixture of products; for instance, nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane are produced by treating propane with nitric acid in the gas phase (e.g. 350–450 °C and 8–12 atm).
Nitromethane, sometimes shortened to simply "nitro", is an organic compound with the chemical formula CH 3 NO 2.It is the simplest organic nitro compound.It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent.
Lean air is a gas mixture with an oxygen content lower than 20.95% (the oxygen content of the normal breathing air).Lean air is made from a gas mixture of air with nitrogen or of pure oxygen with nitrogen and is used in several production processes where a product covering with pure nitrogen can be dangerous, undesirable or more expensive.
In chemical looping combustion, the oxygen required to burn the coal is produced internally by oxidation and reduction reactions, as opposed to using more expensive methods of generating oxygen by separating it from air. [5] At present in the absence of any need to reduce CO 2 emissions, oxy-fuel is not competitive.
Too much air would result in an oxygen content exceeding 5%, and too much fuel oil would result in the carryover of dangerous hydrocarbon gas. The flue gas is cleaned and cooled by the scrubber tower. Various safety devices prevent overpressure, the return of hydrocarbon gas to the engine room, or having a supply of IG with too high oxygen content.
