Ammonia - Wikipedia

Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct characteristic of a pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to

Particulates - Wikipedia

Sources of atmospheric particulate matter. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation and sea spray.Human activities, such as the burning of fossil fuels in vehicles, stubble burning, power plants, road dust, wet cooling towers in cooling systems and various industrial processes, also generate significant amounts of

Flue-gas desulfurization - Wikipedia

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

May 06, 2021 · The relatively low concentration of PM 10 at the receptor was probably influenced by the existence of a natural forest barrier (approx. 0.8 km in a straight line), the lack of local industries or enterprises that influence air quality (closest industrial activity approx. 13 km from the receptor), and the high average wind speed (7.1 m/s), which
