Sulfur dioxide in coal-fired power stations is typically removed using a process called flue gas desulfurization (FGD). This can be done through methods such as scrubbing with a limestone slurry or using specialized equipment like dry sorbent injection systems. These processes help to capture and neutralize sulfur dioxide before it is released into the atmosphere.
What else can I help you with?
How do you reduce sulfur dioxide in coal fired power stations?
Using a method called flue gas desulphurisation which involves the addition of a calcium oxide. The calcium oxide basically absorbs the sulphur dioxide on its way out of the flues; economically, useful products are produced such as gypsum which can be used as plaster.
Why are waste gasses from coal-fired power stations passed through calcium carbonate?
Waste gases from coal-fired power stations are passed through calcium carbonate to remove sulfur dioxide from the gas stream through a process known as flue gas desulfurization. In this process, the calcium carbonate reacts with the sulfur dioxide to form calcium sulfate, a solid compound that can be easily removed, reducing air pollution and environmental impacts.
What gases are released from coal fired power station?
Coal fired power stations release carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM) into the atmosphere. These emissions contribute to air pollution and global climate change.
How is calcium carbonate used in coal fired power stations?
Calcium carbonate is commonly used as a sorbent to remove sulfur dioxide (SO2) emissions from flue gas in coal-fired power stations. When calcium carbonate reacts with SO2, it forms calcium sulfate, which can be captured and disposed of. This process helps to reduce air pollution and comply with environmental regulations.
Which country produced the most sulfur dioxide?
China is the largest producer of sulfur dioxide emissions in the world, with a significant portion coming from industrial activities such as coal-fired power plants and manufacturing.

What are the two chemical pollutants that are produced by coal fired power stations?
Most coal burned in power stations contains small amounts of the metal mercury. This metal is released and vaporized as the coal burns. Some coal, particularly lower-quality bituminous coal, contains nitrogen compounds. The nitrogen in this coal (and sometimes nitrogen from the air) combine with oxygen to produce various nitrogen oxides, some of which catalyze the formation of ozone in the lower atmosphere. Most modern coal-fired power stations have very efficient combustion, so they produce very little carbon monoxide, but some older plants produce significant (but still small) quantities. Carbon dioxide isn't universally considered a pollutant, but it is the main combustion product of coal. Some coal contains sulfur or sulfur compounds. These can be released by burning to produce sulfur dioxide, which reacts with water in the atmosphere to produce sulfurous and sulfuric acids, which are significant components of acid rain.
Why sulfur emissions from coal-fired power plants are considered an environmental problems?
Sulfur emissions from coal-fired power plants contribute to air pollution by forming sulfur dioxide (SO2), which can react with other compounds in the atmosphere to form acid rain. This can harm ecosystems, damage buildings and infrastructure, and pose health risks to humans. Additionally, sulfur dioxide can contribute to the formation of fine particulate matter, which can negatively impact air quality and human health.
Are green house gases more or less than carbon dioxide?
Carbon Dioxide IS a 'greenhouse gas' ! There are still too many coal-fired power stations that are releasing tons of CO2 into the atmosphere !
What is bad about gas fired power stations?
Gas fired power stations contribute to global warming by releasing greenhouse gases such as carbon dioxide. They also require extraction and transportation of fossil fuels, which can have negative environmental impacts. Additionally, there are concerns about the potential for gas leaks and accidents at these facilities.
What is two thirds of the sulfur dioxide that pollutes the air produced by?
Sulfur dioxide in the air is mainly produced by burning fossil fuels like coal and oil. Two thirds of this pollution comes from coal-fired power plants, industrial processes, and automobiles.
How could acid rain be reduced in coal fired power stations?
== == Acid gas emissions cold be reduced by: * Reducing demand on the station (less fuel burned less emissions) * Make the staitons more efficient * Use a lower sulfur coal * Improve NOx forming conditions in the boilers * Remove Acid Gases by treatmnt before discahrge * Close inefficient stations * Have a shedding strategy for the network that uses lower politon emitting stations first
Does coal burning power plants release radioactive waster?
While coal fired plants release particulates, carbon dioxide and sulfur dioxide as major pollutants they also release radioactive materials which were contained in the coal as aerosols.
