Combustion process, whether used for electricity generation or in Essay

Combustion process, whether used for electricity generation or in engines for transport, produce mobile emissions of environmental concern - Essay ExampleAcid rain is due to the presence in the glory of SO2 and NOx which, after a series of replys, are deposited as nitric and sulphuric acid in the form of rain. Particulate matter is known to cause serious respiratory diseases.Carbon requisition form is a method that allows the reduction of CO2 by capturing it at its source (e.g. a power plant) and storing it in non-atmospheric reservoirs much(prenominal) as geologic or oceanic reservoirs (Herzog). The Sleipner project is a working example of carbon sequestration technology. Off the coast of Norway in the North Sea, it is in fact the worlds first commercial CO2 set out and storage project collecting about one million metric tons of CO2 separately year since it was opened in 1996 (Sleipner CO2 project).The term scrubber is used to refer to a conclave of air pollution control dev ices that aid the removal of fine particles and/or gases (especially acid gases) from industrial pall streams. Scrubbers work by either physically removing substances from the exhaust gas stream or by chemically neutralising them so that they providenot do any harm once released into the environment.Wet chaparral is used to clean gases from pollutants and particulates by putting in contact the exhaust gas stream with the scrubbing solution. The scrubbing solution heap simply be water for the removal of dust or a chemical solution which contains reagents that place specifically target certain compounds. Removal efficiency of pollutants is improved by increasing residence sequence in the scrubber or by the increase of surface area of the scrubber solution. 2.2. Dry scrubbingDry scrubbing is generally used to subscribe acid gases, such as SO2, primarily from conflagration sources. All dry scrubbing systems consist of two main devices 1) a device to introduce a solid sorbent mat erial into the gas stream and 2) a particulate control device to remove reaction products, excess sorbent material, any particulate matter already in the flue gas.2.3. saltwater scrubbingThe natural buffering capacity of seawater can be taken advantage of by exploitation it as a sorbent in a scrubbing system. When SO2 comes into contact with seawater a reaction takes place between the SO2 and the CaCO3 present in the seawater, producing CaSO4 and CO2. This reaction is complete in a very shortstop time, so the equipment required for seawater scrubbing can be compact. 3. NOx3.1. Primary measuresPrimary measures can be applied pre-combustion. In Bowin low NOx technology, air and
