Sulphur scrubbers on coal fired power plants use a multistage system:
- The stack gasses containing sulphur dioxide gas are passed over a catalytic bed with the addition of extra oxygen to convert the sulphur dioxide gas to sulphur trioxide gas.
- The stack gasses now containing sulphur trioxide gas are passed through a chamber containing water spray and the sulphur trioxide gas dissolves in the water producing highly concentrated sulphuric acid, which precipitates out of the stack gasses as a liquid.
- The concentrated sulphuric acid is concentrated more producing "Oleum" a very oily industrial grade of sulphuric acid. "Oleum" can often be sold to chemical companies with no further processing.
- If the market for "Oleum" does not offer enough demand, then it can be processed through additional steps to extract the dry sulphur as yellow crystals called "flowers of sulphur".

What effects does sulphur dioxide have to the atmosphere?
Sulphur dioxide in the atmosphere can contribute to the formation of acid rain, which can harm aquatic ecosystems and vegetation. It also reacts with other pollutants to form particulate matter, which can affect air quality and human health. Additionally, sulphur dioxide can contribute to the formation of haze and reduce visibility.
What are the preventive measures of sulphur dioxide?
Preventive measures for sulphur dioxide pollution include using cleaner fuel sources, implementing regulations on industrial emissions, using technologies like scrubbers to reduce emissions, and promoting energy efficiency to decrease overall emissions. Regular monitoring and enforcement of air quality standards are also important in preventing sulphur dioxide pollution.
What can be done do about sulfur dioxide pollution?
Finding/using fuels with a lower sulphur content would be a large step. Technology to capture sulphur dioxide from combustion byproducts would be a second large step. Finding an economical use for for the captured byproducts would make the second step much more attractive to those who produce sulphur dioxide.
Since 1977 scrubbers have been required for the exhault fumes of all new fossil fuel burning power plants and smelters These devices are used to reduce emissions of?
sulfur dioxide and other pollutants by trapping them before they are released into the air. Scrubbers work by using a wet process to scrub the emissions and remove harmful particles and gases, helping to improve air quality and reduce environmental impact.
How is sulfur dioxide removed from coal in power station emissions?
Sulfur dioxide is typically removed from coal emissions using a process called flue gas desulfurization (FGD), which utilizes either wet scrubbers or dry scrubbers. Wet scrubbers use a liquid solution to absorb sulfur dioxide from the flue gas, while dry scrubbers typically use a powdered sorbent. These methods help to reduce sulfur dioxide emissions and comply with environmental regulations.
What is used to reduce SO2 emissions from coal burning power plants?
Flue gas desulfurization systems, such as wet scrubbers or dry scrubbers, are commonly used to reduce sulfur dioxide (SO2) emissions from coal burning power plants. These systems remove SO2 from the exhaust gases before they are released into the atmosphere, helping to mitigate air pollution and its associated environmental and health impacts.
How can sulphur impurities be dealt with in fossil fuels?
Sulphur impurities in fossil fuels can be dealt with through a process called desulphurization. This involves treating the fuels with a desulphurizing agent to remove the sulphur compounds present. Alternatively, low-sulphur fossil fuels can be used, or technologies like fuel scrubbers can be employed to reduce sulphur emissions during combustion.
What are scrubbers in smokestacks?
Scrubbers use a wet limestone slurry to absorb sulfur as it passes though. Filters are large cloth bags that catch particles as they go through the cloth. Scrubbers are more common, and can reduce sulfur emissions by up to 90 percent, when working properly. Still, smaller particulates are less likely to be absorbed by the limestone, and can pass out the smokestack into the air. yehhh the answerr
What is sulphur precipitator?
A sulphur precipitator is a device used to remove sulphur dioxide from industrial exhaust gases. By passing the gases through the precipitator, sulphur dioxide is converted into a solid particulate form that can be easily collected and disposed of. This helps reduce air pollution and its negative effects on the environment and human health.
How can we reduce your carbon footprint?
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.
How can reducing sulfur content in fuel reduce acidic gas emission?
reducing the sulphur content in fuels will effectivily reduce the amount of sulphur realised into the atmosphere. In the gas phase sulphur dioxide is oxidised by reaction with the hydroxyl radical via an intermolecular reaction: SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water, sulphur trioxide (SO3) is converted rapidly to sulphuric acid: SO3(g) + H2O(l) → H2SO4(l) the lower the sulphur released into the atmosphere the lower the amount of sulphuric acid is formed
Why should the sulfur dioxide be removed from the waste gases?
Sulfur dioxide should be removed from waste gases because it is a major air pollutant that can contribute to acid rain, respiratory problems, and environmental damage. By removing sulfur dioxide, we can reduce these negative effects and improve air quality.
