Air Pollution Control Concepts

The video discusses methods to reduce air pollution, focusing on reducing emissions at the source, laws and regulations like the Clean Air Act and CAFE standards, and technologies such as catalytic converters and scrubbers. It also covers specific technologies for vehicles and coal power plants, and concludes with a practice exercise.

Which of the following is a common-sense step to reduce air pollution?

• Increasing meat consumption

• Using more plastic products

• Riding bikes instead of cars

• Driving more frequently

What is the primary purpose of the Clean Air Act?

• To promote the use of plastic

• To set acceptable levels of air pollutants

• To ban all forms of transportation

• To increase fossil fuel consumption

How do CAFE standards help in reducing air pollution?

• By increasing the number of vehicles on the road

• By banning electric vehicles

• By promoting the use of coal

• By setting higher fuel economy standards

What is the role of pollution credits in reducing emissions?

• They allow companies to pollute more

• They incentivize companies to reduce emissions

• They are used to increase emissions

• They are unrelated to pollution control

What is the function of a vapor recovery nozzle?

• To capture volatile organic compounds

• To enhance the smell of gasoline

• To release more hydrocarbons

• To increase gasoline fumes

How does a catalytic converter help reduce vehicle emissions?

• By increasing carbon monoxide emissions

• By converting harmful gases into less harmful substances

• By releasing more nitrogen oxides

• By enhancing fuel consumption

What is the purpose of using crushed limestone in coal-fired power plants?

• To release more nitrogen oxides

• To enhance coal combustion

• To trap sulfur dioxide as a solid

• To increase sulfur dioxide emissions

How does fluidized bed combustion reduce emissions?

• By releasing more sulfur dioxide

• By increasing combustion temperatures

• By reducing the efficiency of coal burning

• By lowering combustion temperatures and improving efficiency

What is the function of a wet scrubber in emission control?

• To enhance the smell of emissions

• To trap and convert air pollutants

• To increase particulate matter

• To release more nitrogen oxides

How does an electrostatic precipitator work?

• By increasing particulate emissions

• By releasing more carbon monoxide

• By charging particles to stick to plates

• By enhancing the combustion process
