Acid Rain And How To Scientifically Prevent It

504 words - 3 pages

Acid rain has caused damage to the environment both in nature and in man-made communities for decades. Acid rain is precipitation that has reacted with harmful compounds of mostly Nitrogen, Sulfur and Carbon. These compound emissions are emitted from factories, motor vehicles and electricity generation. The discovery of acid rain was 1852 in Manchester England, but only in the 1960's did scientists start studying the effects of it. Many people think that since acid rain is precipitation we can not control it. They are right, we can not control the precipitation but we can control the destructive emissions that are the main cause of it. There are many ways ...view middle of the document...

A Wet scrubber is a tower that uses a fan to draw hot stack gasses into the tower and adds limestone to the mix to neutralize it and create a sulfate that is then removed from the tower and either sold as Gypsum or dumped in a landfill.Besides the Wet Scrubber there are other different yet effective FGD's. Some of these include, but are not limited to, Venturi-Rod Scrubbers, Packed Bed Scrubbers and Spray Towers. The Venturi-Rod Scrubber is the most expensive Wet Scrubber to operate and own, mainly because of the cost of the power necessary to run it. What the Venturi-Rod Scrubber does is accelerate the unsafe gas to a high velocity as it goes up the tower. At the point of maximum velocity there are sprayers that inject water into the tower. The turbulence caused by the gas hitting the water liquidizes the gas so it turns into miniscule droplets. By creating these droplets the necessary surface area is made to support mass transfer.Acid Rain will keep causing damage for centuries until it is stopped. One day in the future scientists may find a way to permanently abolish acid rain. For now all we can do is help reduce the emissions of harmful gasses from factories, power plants and everyday cars.Works Cited"Acid rain -." Wikipedia, the free encyclopedia.
