The most common process is 2 steps:
- Run the flue gasses through a catalyst with excess oxygen to convert the SO2 to SO3.
- Bubble that through a tank of crushed limestone and water slurry to produce gypsum CaSO4.
Another process is also 2 steps:
- Run the flue gasses through a catalyst with excess oxygen to convert the SO2 to SO3.
- Bubble that through a tank of water to produce sulfuric acid H2SO4.
In either process, the gypsum or sulfuric acid can be sold.

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 did the formation of seas and oceans change the amount of carbon dioxide?
The formation of seas and oceans helped to regulate the amount of carbon dioxide in the atmosphere by absorbing and storing it in the water. This process helped to reduce the levels of carbon dioxide in the atmosphere, which contributed to creating a more stable climate on Earth.
Fact about carbon dioxide produced by planes?
Planes produce carbon dioxide as a byproduct of burning jet fuel, contributing to greenhouse gas emissions and climate change. The aviation industry is working on improving fuel efficiency and exploring alternative fuels to reduce its carbon footprint.
At which temperature would plants most likely use the greatest amount of carbon dioxide?
Plants are likely to use the greatest amount of carbon dioxide at temperatures around 25-30 degrees Celsius, as this is when their metabolic processes are most active. Cooler temperatures can slow down plant metabolism and reduce carbon dioxide uptake, while excessive heat can stress the plants and reduce their ability to photosynthesize efficiently.
Cement work might reduce carbon dioxide why?
The cement work cannot reduce carbon dioxide. In fact, the cement work increases carbon dioxide because carbon dioxide is emitted during the production of cement.
How can you reduce the amount of sulfur dioxide released?
Some types of coal contain sulphur, and when burned, release sulphur dioxide; this is the major source of sulphur dioxide emissions. There are ways to scrub pollutants out of the smoke emitted by coal-burning power plants, however, I personally think that it makes more sense to stop burning coal and switch to other methods of power generation.
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 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.
Why do you analyze sulfur in coal?
The amount of sulphur in coal is directly related to the amount of sulphur dioxide it would produce on burning and hence it becomes necessary to check sulphur content since there are emission limits on amount of sulphur dioxides that can come out since it is an air pollutant. To remove sulphur one might consider adding carbonates as it would help convert sulphur dioxide to sulphates which can be removed along with the ash.
How does calcium carbonate reduce harmful emissions from coal-fired power stations?
Coal contains sulphur and when this is burnt(heated) sulphur dioxide is produced, this is a greenhouse gas. To remove this greenhouse gas, this gas is passed a mechanism like a shower that is able to dissolve it and make it an acid. Then this acid sulphur is neutralized with calcium carbonate to form calcium sulphate, water and carbon dioxided
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.
Does an economical car reduce the amount of carbon dioxide in the air?
No car can actually reduce the amount of carbon dioxide in the air, but an economical car will add less additional carbon dioxide to the air than a less economical one.
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.
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.
Is Sulphur dioxide pollutant?
Yes, sulfur dioxide (SO₂) is considered a pollutant. It is a colorless gas with a pungent odor, primarily produced from burning fossil fuels, volcanic eruptions, and industrial processes. When released into the atmosphere, it can contribute to acid rain, respiratory problems, and environmental degradation. Efforts to reduce sulfur dioxide emissions are important for improving air quality and public health.
What would reduce acid rain?
Acid rain is caused by factories burning sulphur, which produces sulphur dioxide. Cars also burn fuel which contributes to acid rain, so if people walked more and factories reduced or in fact stopped the amount of sulphur they burnt, then we wouldn't have so much acid rain. Consider 6 billion weekly loads of laundry and all those cooked meals.
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
