Burning low-sulfur-content coal to reduce so2 emissions can be done by power plants. Coal and wood are used in power plants to reduce SO2 emissions. Reducing sulfur dioxide and NOx in the air can be accomplished by pretreating and processing coal.
Coal-to-liquids (C2L) plants use coal as a feedstock for the production of liquid fuels. These plants can produce a wide range of fuels, including gasoline, diesel, kerosene, propane, and natural gas. They also produce biofuels, which can be used to generate electricity or heat homes and businesses.

How do power plants cause air pollution?
They emit harmful pollutants, including mercury, non-mercury metallic toxics, acid gases, and organic air toxics such as dioxin. The United States has power plants that emit mercury (50 percent), acid gases (75 percent) and many toxic metals (20-60 percent). Mercury is a neurotoxin that causes damage to the central nervous system.
It is also a carcinogen, which means that it can cause cancer in humans. Mercury has been linked to a wide range of health problems, from birth defects to learning disabilities. The EPA estimates that mercury emissions from power plants account for more than one-third of the total U.S. mercury pollution from sources other than landfills and incinerators.
How can we prevent pollutants from coal power plants?
Coal cleaning by ‘washing’ has been standard practice in developed countries for some time. When the coal is burned, it reduces emissions of ash and sulfur dioxide. In the UK since the 1970s, electrostatic precipitators and fabric filters have been used to remove 99% of the fly ash from the flue gases.
In a recent study published in Environmental Science & Technology, researchers at the University of California, Berkeley, found that coal-fired power plants emit more than twice as much particulate matter (PM2.5) as they are supposed to.
The study, which was funded by the US Environmental Protection Agency (EPA) and the National Institute for Occupational Safety and Health (NIOSH), was the first to quantify the amount of particulates emitted by a coal power plant in a real-world setting, and it was based on data from a single US coal plant, the San Onofre Nuclear Generating Station (SONGS) in San Diego, California.
The researchers used a computer model to simulate the effects of air pollution on the health of people living near the SONGS plant.
Which type of power plant causes air pollution?
Air pollution from coal-fired power plants is linked to asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other health problems. The EPA’s Clean Power Plan, the centerpiece of President Obama’s climate change agenda, aims to reduce carbon dioxide emissions from existing coal plants by 32 percent from 2005 levels by 2030.
What device can be used to remove toxic pollutants from power plant emissions?
Air pollution control devices used to mitigate nitrogen oxide emissions produced by the burning of fossil fuels are known as catalytic reactors. In the United States, the Environmental Protection Agency (EPA) and the U.S. Nuclear Regulatory Commission (NRC) are responsible for regulating the use of SCRs.
The EPA regulates the design, construction, operation, maintenance, and decommissioning of nuclear power plants, while the NRC oversees the safety and security of the nation’s nuclear facilities. Both agencies are charged with ensuring that nuclear plants are safe and secure. In addition, both agencies have the authority to issue permits for the construction and operation of new nuclear reactors.
How is pollution reduced in natural gas based power plant?
Natural gas can be burned with a flame in the conventional method. Researchers are trying to eliminate the flame and replace it with a catalyst that burns methane at a lower temperature. “This is the first time we’ve been able to show that it can work at room temperature.
It’s an important first step, and we’re going to continue to work on it to see if we can improve the performance.” The research was funded by the National Science Foundation, the U.S. Army Research Office and the Air Force Office of Scientific Research.
How conservation of energy can lead to pollution control?
Increased consumption is also resulting in pollution of the environment. Energy conservation results in a better and a greener environment, national security and higher individual savings. Clean energy resources include renewable energy. Fossil fuels have a bigger impact on the health of the planet. In addition, renewable energy has the potential to reduce the cost of energy.
In the United States, for example, the price of electricity has fallen by more than 50 percent in the last 20 years. This is due in part to the fact that wind and solar power are now cheaper than coal, natural gas, and nuclear power.
