Technologies to Control Air pollution

Introduction:

Some people may wonder why pollution needs to end when the ecosystem is not as badly damaged as some claim. The environment is actually far more impacted than any of us realize. In addition to providing us with clean air, a better lifestyle, clear visibility, a healthy environment for all Earth's inhabitants, and other benefits, controlling pollution will lower health risks, liability risks, and economic losses.

The governments of different nations and organizations throughout the world have made numerous efforts to lessen the negative impacts of pollution on our environment. The United Nations Environment Programme is one of the initiatives the UN has taken, with the goal of inspiring people all over the globe to collaborate, protect the environment, and take action to raise standards of living for not just current generations but also future generations. In order to bring representatives of all member countries together to discuss environmental challenges, raise awareness, and spur action, the United Nations has also proclaimed June 5 of each year as World Environment Day.

Oneofthe most promising areas for enhancing air quality is the development ofnew technology. We've created techniques to stop air pollution both inside and outside, from catalytic converters to low-emitting consumer goods. We will talk about six innovations that are actively preventing air pollution from hurting our environment and our health in recognition of these technological advances. Regulatory and market-based approaches to reducing air pollution had already been considered; each had advantages and disadvantages of its own. We will address each invention separately rather than discussing technology as a whole because new innovations typically do not have the same kind of cost-benefit ratio as these other ways.

Here are some of the technologies that are clearing our skies:

Multi – pollutant Monitoring Devices: Although this piece of equipment does not directly reduce emissions or clean the air, it is still an essential component of the system that controls air pollution. Factories, power plants, and other sources of pollution all produce more than one pollutant; on the other hand, some pollution control methods do so as well. Multi-pollutant monitoring lowers the expense and time burden of ambient pollution monitoring while enabling regulatoryauthorities to ensurecompliance with emission limitations for a varietyofpollutants.

Catalytic Convertors: One of the most important sources of air pollution worldwide is vehicle exhaust. Gasoline and diesel-powered cars were fitted with catalytic converters, a device that catalyzes a redox reaction that converts harmful air pollutants into less harmful pollutants, in response to increasingly rigorous environmental restrictions starting in the 1970s. There are some drawbacks to catalytic converters. For starters, these devices may limit exhaust flow, lowering vehicle performance and fuel efficiency. Moreover, catalytic converters have a warmup time during which the car can release as much pollution as it wants. These converters have drawbacks as well; many of them call either platinum or palladium, which are scarce metals that pollute during the refining process.

Scrubbers: Scrubbers are a sort of pollution-control tool that eliminates air pollutants from industrial emissions, including Sulphur dioxide, chlorine, hydrogen sulphide, and hydrogen chloride. Wet scrubbers and dry scrubbers are the two primary categories of scrubbers that will be covered. Wet scrubbers, which range in energy level, employ a liquid (often water) to collect particles or gases from an air stream. A spray tower is a typical low-energy wet scrubber that disperses liquid by sending exhaust through an open vessel equipped with sprayers. The liquid either absorbs the target gas or takes up floating particles as the exhaust passes through the apparatus. Dryscrubberswork similarly, except instead ofspraying a liquid, thesedevicesspray dry chemicals into the flue stream, neutralizing gases before they can enter the atmosphere. Scrubbers are a very useful technology for pollution management because they keep populations near industrial hubs like power plants and water treatment facilities from being harmed by harmful air pollutants. Furthermore, because these devices don't interfere with production, commercial and industrial activitycan continuewithout an increase in air pollution.

CFC and HCFC Substitutes: After the signing of the Montreal Protocol in 1987, the manufacturing and use of hydrofluorocarbons (HCFCs) and chlorofluorocarbons (CFCs), both of which reduce the ozone layer, were gradually phased out. We needed to develop substitutes for CFCs and HCFCs because they were often employed as solvents, propellants, and refrigerants yet had a high potential to deplete the ozone layer (ODP). Hydrofluorocarbons

(HFCs) are one of the primary CFC and HCFC replacements used today. Long story short, HFCs lack chlorine, which is the chemical that is primarily to blame for destroying the ozone layer

Conclusion:

Environmentalpollution is burning issue in the current situation. There should be some measures to control the pollution if not it will affect entire world and all the living and nonliving things exist on the earth. Due to increase in pollution the global warming started and the effect of that every year average temperature is increasing by 5 degrees. The iceberg present in the Atlantic Ocean is melting by increasing the sea water level. This will lead to the increase in the volume of salt water. Very soon there will be shortage of drinking water. Major reason for pollution is the Carbon emission due to various sources like industries, vehicles, burning wastages, plastics, charcoal, excessive use of electronic gadgets, deforestation and so on. This article is discussed about some of the tools which will reduce the carbon emitted by various sources up to certain extent.
